Clinoptilolite is a natural microporous aluminosilicate whose structure underly unique physicochemical properties. These properties support its growing use in medical and pharmaceutical applications. Clinoptilolite has a high surface area and a high ion exchange capacity exploited in many medical applications. Recently, its selective adsorption properties have prompted researchers to study its potential for controlled or targeted drug delivery. In this particular field of application its unmodified, naturally occurring form showed limitations due to its hydrophilicity and small pore size. This is why the natural clinoptilolite mainly shows transient uptake of small or polar drug molecules and is not appropriate for delivery of larger or nonpolar pharmaceutical compounds. The presented review provides a summarized overview of the clinoptilolite physical-chemical properties relevant for its potential drug delivery properties and examines various strategies used to modify the clinoptilolite surface with different organic and inorganic agents. One large portion of studies have provided data on usage of surfactants, chitosan, amine-containing polymers, and green-synthesized nanoparticles for improvement of the clinoptilolite adsorption capacity. Therapeutic functionality of clinoptilolite has been achieved by these surface modifications, i.e. chitosan modified clinoptilolite enabled targeted delivery and wound healing applications. Nanoparticles usage for surface modification, i.e. CaO and MgO were also successfully tested for sustained 5-fluorouracil release in colon cancer therapy. Moreover, the clinoptilolite surface has been successfully functionalized with antioxidant and enzymatic agents. In summary, modifications of the clinoptilolite surface are a growing area of research for obtaining versatile platforms for controlled drug delivery and advanced therapeutic systems. Some of the fields that might benefit the most are oncology and wound care.

斜发沸石是一种天然的微孔铝硅酸盐，其结构具有独特的物理化学性质。这些特性支持其在医疗和制药应用中的日益增长的用途。斜发沸石具有高表面积和高离子交换能力，在许多医疗应用中得到了利用。最近，它的选择性吸附特性促使研究人员研究它在控制或靶向药物递送方面的潜力。在这个特殊的应用领域，由于其亲水性和小孔径，其未经修饰的自然存在形式显示出局限性。这就是为什么天然斜发沸石主要表现为对小分子或极性药物分子的瞬时摄取，而不适合递送较大或非极性药物化合物的原因。本文综述了斜发沸石的物理化学性质及其潜在的药物传递特性，并研究了使用不同的有机和无机试剂修饰斜发沸石表面的各种策略。很大一部分研究提供了使用表面活性剂、壳聚糖、含胺聚合物和绿色合成纳米颗粒来提高斜沸石吸附能力的数据。斜发沸石的治疗功能是通过这些表面修饰实现的，即壳聚糖修饰的斜发沸石能够靶向递送和伤口愈合应用。用于表面修饰的纳米颗粒，即CaO和MgO，也成功地测试了在结肠癌治疗中持续释放5-氟尿嘧啶的效果。此外，斜沸石表面已成功地用抗氧化剂和酶功能化剂。综上所述，对斜沸石表面的修饰是一个不断发展的研究领域，它可以获得用于控制药物输送和先进治疗系统的多功能平台。一些可能受益最大的领域是肿瘤学和伤口护理。

A novel soy protein isolate (SPI)/ZnAl layered double hydroxide (LDH) biocomposite was developed as an efficient and sustainable adsorbent for the removal of azo food dye tartrazine from aqueous systems and commercial food products. The biocomposite was synthesized via a simple co-precipitation method and characterized to confirm successful integration of SPI with LDH, resulting in a functional, porous hybrid material. The optimized SPI/ZnAl LDH composition exhibited rapid and highly efficient dye adsorption under acidic conditions, driven by electrostatic interactions, hydrogen bonding, and interlayer anion exchange. Adsorption behavior followed both Langmuir and Freundlich isotherm models, indicating favorable and spontaneous dye uptake dominated by physisorption. The biocomposite demonstrated effective dye removal from real food matrices and food dye wastewater, highlighting its practical applicability. In addition, the material showed notable antibacterial activity against both Gram-positive and Gram-negative bacteria and retained good adsorption performance over multiple regeneration cycles. These results establish SPI/ZnAl LDH biocomposites as promising eco-friendly materials for simultaneous dye removal and antimicrobial applications in food safety and wastewater treatment.

To date, significant progress has been made in the research field of nano-pesticides. Mesoporous silica nanoparticles (MSNs) are among the most widely used carrier materials in the formulation of nano-pesticides, owing to their abundant pore structure and favorable biocompatibility. This review extends beyond a conventional summary of preparation methods and innovatively elucidates the intrinsic relationships between reagent selection and pesticide loading performance, offering a novel paradigm for the rational design of efficient drug delivery systems. Meanwhile, this article focuses on two major cutting-edge research directions over the past five years: one involves stimuli-responsive nano-pesticides based on MSNs, such as those triggered by pH, enzymes, or light, which enable on-demand and precise delivery of pesticides; the other encompasses function-enhanced nano-pesticides that significantly improve pesticide targeting and utilization efficiency through the co-loading of adjuvants or the construction of multi-component composite materials. This article provides a forward-looking discussion on the environmental behavior and potential risks associated with these novel nano-pesticides and concludes with an outlook on the challenges and future innovation pathways for their practical application, aiming to contribute new momentum to the development of smarter, safer, and multifunctional agricultural nanotechnology products.

Novel hybrid nanocomposites were tentatively prepared by grinding, heating and purifying in Soxhlet preset amounts of lawsone and methyl orange dyes with the microporous palygorskite clay mineral, i.e., following the ancient recipe of the famed Maya Blue pigment. These composites were investigated in the various synthesis steps with a multi-analytical approach (XRPD, FE-SEM-EDS, BET-SSA, TGA-DSC, UV–Vis, ATR-FT-IR and Fluorescence spectroscopies), which allowed understanding their structural features and physicochemical properties, unveiling the nature and sites of the interactions existing between the host and the guest. Also, their stability was evaluated through harsh chemical attacks, monitoring colour changes and spectral features.

The obtained outcomes proved that lawsone forms a stable hybrid composite after heating with palygorskite, establishing H-bonds between the C=O groups on its quinonoid ring and the structural/zeolitic water in the grooves carving the clay fibrils surface. Such a stability, coupled to an observed colour shift after pH fluctuations (yellow in acids; orange in alkalis), suggests that this composite might be used as a solid-state, reversible acid-base indicator, a colorimetric-electrochemical sensor for anions or for bio-reduction of pollutants in remediation activities.

Methyl orange, on the other hand, undergoes systematic degradation when heated together with palygorskite, forming byproducts unable of efficiently binding to the host framework. Despite a presumed affinity of palygorskite for absorbing azo dyes, methyl orange is not firmly stabilized on the host structure due to an incipient mutual electrostatic repulsion that prevents bonding and shielding during grinding, paving the way for an inevitable decay of the molecule after heating.

采用古代著名的玛雅蓝颜料配方，以微孔粘土矿物为原料，采用索氏预设量的lawsone和甲基橙染料进行研磨、加热和纯化，初步制备了新型杂化纳米复合材料。通过多种分析方法（XRPD, FE-SEM-EDS, BET-SSA, TGA-DSC, UV-Vis， ATR-FT-IR和荧光光谱）研究了这些复合材料的不同合成步骤，从而了解了它们的结构特征和物理化学性质，揭示了宿主和客体之间存在相互作用的性质和部位。此外，通过严酷的化学攻击、监测颜色变化和光谱特征来评估它们的稳定性。所得结果证明，lawsone与坡筋石加热后形成稳定的杂化复合材料，其醌环上的C=O基团与粘土原纤维表面凹槽中的结构/沸石水之间建立了氢键。这种稳定性，加上在pH值波动后观察到的色移（酸性为黄色，碱性为橙色），表明该复合材料可能用作固态可逆酸碱指示剂、阴离子比色电化学传感器或用于修复活动中污染物的生物还原。另一方面，甲基橙与坡齿石一起加热时会发生系统降解，形成无法有效结合到宿主框架的副产物。尽管假定坡齿石具有吸收偶氮染料的亲和力，但甲基橙并没有牢固地稳定在宿主结构上，这是由于初始的相互静电斥力，在研磨过程中阻止了键合和屏蔽，为加热后分子不可避免的衰变铺平了道路。

Hydrotreatment of lubrication oil waste can effectively remove sulfur and some other impurities, which can benefit resource regeneration and result in positive environmental and economic impact. A dual-template strategy employing PMMA microspheres and CTAB was adopted to synthesize porous Y-type zeolites with tunable macropore dimensions. The resulting Y-type zeolite framework exhibited an ordered system of mesopores and interconnected macropores, which was subsequently loaded with NiMo active metals for the hydrogen desulfurization (HDS) of benzothiophene during waste lubricating oil treatment. Effect of various macropore size on benzothiophene hydrogenation performance was investigated. The results showed that macropore size variation played a crucial role in the HDS process. The macroporous structure also helps reduce excessive growth of MoS₂ nanosheets, maintaining a high number of stacked layers and short sheet lengths. This promotes the formation of highly dispersed MoS₂ nanosheet structures, thereby facilitating the development of the active NiMoS phase. Furthermore, catalyst with the largest macropore size achieved a benzothiophene HDS conversion of up to 99.6 %, with an activation energy of 29.85 kJ/mol.

润滑油废弃物加氢处理可以有效去除硫和其他一些杂质，有利于资源再生，产生积极的环境和经济影响。采用PMMA微球和CTAB双模板策略合成了大孔尺寸可调的y型多孔分子筛。所制得的y型分子筛骨架具有有序的中孔和相互连接的大孔体系，随后负载NiMo活性金属用于废润滑油处理过程中苯并噻吩的氢脱硫。研究了不同大孔尺寸对苯并噻吩加氢性能的影响。结果表明，大孔大小的变化在HDS过程中起着至关重要的作用。大孔结构还有助于减少MoS2纳米片的过度生长，保持高堆叠层数和短片长。这促进了高度分散的MoS2纳米片结构的形成，从而促进了活性NiMoS相的发展。此外，最大大孔径催化剂的苯并噻吩HDS转化率高达99.6%，活化能为29.85 kJ/mol。

A novel approach for steam-assisted synthesis of zeolite MFI based on the crystallisation of silica grains impregnated with the aqueous solution containing structure directing template, alkali and a source of aluminum has been developed. Both powdered MFI samples and binder-free MFI catalysts have been prepared using this method. It provides significant advantages over conventional hydrothermal crystallisation allowing for 3-5-fold reduction in water and template consumption, while increasing the zeolite yield and autoclave productivity by a factor of 2–3. Furthermore, the synthesis procedure is virtually waste-free making it more environmentally friendly. The physicochemical properties of the materials obtained have been investigated utilising X-ray diffraction, X-ray fluorescence, scanning electron microscopy, low-temperature nitrogen adsorption, and temperature-programmed ammonia desorption, while their catalytic performance has been evaluated in toluene disproportionation. The data demonstrate that MFI zeolites produced by steam-assisted crystallisation of impregnated silica are comparable in physicochemical and catalytic properties to zeolites obtained by the traditional hydrothermal method, and that binder-free granulated MFI zeolite is a promising catalyst for toluene disproportionation.

提出了一种蒸汽辅助合成MFI沸石的新方法，该方法是在含有定向结构模板、碱和铝源的水溶液中浸渍二氧化硅晶粒结晶。用这种方法制备了粉末状的MFI样品和无粘结剂的MFI催化剂。与传统的水热结晶相比，它具有显著的优势，可以将水和模板消耗减少3-5倍，同时将沸石产量和热压釜生产率提高2-3倍。此外，合成过程几乎没有废物，使其更加环保。利用x射线衍射、x射线荧光、扫描电镜、低温氮吸附、程序升温氨脱附等方法研究了所得材料的理化性质，并对其在甲苯歧化反应中的催化性能进行了评价。结果表明，水蒸气辅助结晶法制备的MFI沸石的理化性能和催化性能与传统水热法制备的沸石相当，无粘结剂颗粒状MFI沸石是一种很有前景的甲苯歧化催化剂。

Zeolites with uniform pore sizes, high specific surface areas, excellent thermal and hydrothermal stability play a pivotal role in the field of chemical industry. Their applications have yielded substantial economic and social benefits. Despite their widespread utilization, the current synthesis for preparing zeolites still face challenges in terms of environmental sustainability, which strongly limits their further applications. Recent researches have witnessed notable progresses in developing sustainable synthesis of zeolites, including organotemplate-free, solvent-free, and near-neutral synthesis. Notably, the integration of organotemplate-free and solvent-free routes, as well as the combination of solvent-free and near-neutral routes, enables a more sustainable pathway for zeolite production. Very importantly, many zeolite products such as pure silica Beta and Al-rich Beta zeolites using these novel routes have already been scaled up for industrial production. These sustainable syntheses are expected to markedly lower production costs and minimize waste generation, thereby contributing positively to the carbon neutrality in the future.

沸石以其均匀的孔径、高的比表面积、优异的热稳定性和水热稳定性在化工领域发挥着举足轻重的作用。它们的应用产生了可观的经济效益和社会效益。尽管沸石得到了广泛的应用，但目前制备沸石的方法仍面临着环境可持续性方面的挑战，这极大地限制了它们的进一步应用。近年来，沸石的可持续合成研究取得了显著进展，包括无有机模板合成、无溶剂合成和近中性合成。值得注意的是，无有机模板和无溶剂路线的整合，以及无溶剂和近中性路线的结合，为沸石生产提供了更可持续的途径。非常重要的是，使用这些新路线的许多沸石产品，如纯硅β和富铝β沸石，已经规模化用于工业生产。这些可持续的合成预计将显著降低生产成本并最大限度地减少废物产生，从而为未来的碳中和做出积极贡献。

This study synthesized magnetic 4A zeolite (MZA) via an innovative ultrafast Joule heating (UJH) combined with hydrothermal method using hard kaolin and industrial solid waste red mud as raw materials. The synthesized MZA was applied to treat heavy metal ion-contaminated water caused by the ternary lithium-ion battery industry, achieving the “waste-treating-waste' objective. Specifically, UJH first treated red mud at 1100 °C for 20 s (no reducing gas) to convert its iron into magnetite and Si-Al-Na components into soluble species, and simultaneously treated hard kaolin at 800 °C for 20 s to form metakaolin. Subsequently. Metakaolin, reduced red mud, and NaOH (mass ratio 1:0.2:1) were mixed and hydrothermally treated at 90 °C for 10 h to yield MZA. The maximum adsorption capacities of MZA for Ni²⁺, Co²⁺, Mn²⁺, and Cu²⁺ are 80.71 mg/g, 82.73 mg/g, 85.91 mg/g, and 207.20 mg/g, respectively. Adsorption follows the pseudo-second-order kinetic model and Langmuir isotherm model. In the quaternary mixed system, MZA shows high selectivity for Cu²⁺, and the adsorption priority of MZA for these heavy metal ions follows the order of Cu²⁺>Mn²⁺>Co²⁺>Ni²⁺. After five adsorption-desorption cycles, the removal rates of Cu²⁺ and Ni²⁺ by MZA only decreased by 2.48 % and 3.72 %, respectively. Moreover, MZA maintains efficient magnetic separation performance. In summary, the energy-saving, eco-friendly, and safe MZA synthesis strategy provides a promising friendly approach for heavy metal wastewater treatment.

以硬质高岭土和工业固废赤泥为原料，采用创新的超快焦耳加热（UJH）结合水热法制备磁性4A沸石（MZA）。将合成的MZA用于处理三元锂离子电池工业中重金属离子污染的水，达到了“废-治-废”的目的。具体而言，UJH首先在1100℃下处理赤泥20 s（无还原性气体），将赤泥中的铁转化为磁铁矿和Si-Al-Na组分转化为可溶性物质，同时在800℃下处理硬高岭土20 s形成偏高岭土。随后。将偏高岭土、还原赤泥和NaOH（质量比为1:0.2:1）混合，90℃水热处理10 h，制得MZA。MZA对Ni2+、Co2+、Mn2+和Cu2+的最大吸附量分别为80.71 mg/g、82.73 mg/g、85.91 mg/g和207.20 mg/g。吸附遵循拟二级动力学模型和Langmuir等温模型。在四元混合体系中，MZA对Cu2+表现出较高的选择性，MZA对这些重金属离子的吸附优先顺序为Cu2+>；Mn2+>Co2+>Ni2+。经过5次吸附-解吸循环后，MZA对Cu2+和Ni2+的去除率分别仅下降2.48%和3.72%。此外，MZA保持了高效的磁选性能。综上所述，节能、环保、安全的MZA合成策略为重金属废水处理提供了一条有前景的友好途径。

Hydrothermal synthesis is a well-established and scalable route for producing well-ordered zeolites that underpin industrial catalysis, separation, and adsorption. However, the concurrent chemical condensation and structural reorganization occurring at elevated temperatures make it difficult to elucidate how framework order and connectivity emerge from amorphous precursors, hindering the rational design of zeolites with tailored structural and catalytic properties. Here, we employ a time-resolved, multimodal approach to track the crystallization of Silicalite-1 (MFI) at 180 °C over shortened synthesis durations (1–5 h). The results reveal a sequential evolution from short-range ordering to partially organized pre-channels and pre-intersections that gradually link into a continuous microporous framework. Unexpectedly, transient mesopores act as temporary reservoirs for bound water, silanol groups, and template species, mediating condensation and defect healing that drive the assembly of pre-channels and their consolidation into stable intersections. This cooperative interplay between mesopores and framework growth clarifies how hierarchical order develops in the early stages of crystallization. Upon calcination, extended treatment removes residual species, opens pore network, and enhances accessibility, consolidating the matured MFI lattice. The resulting holistic, time-resolved mechanism offers mechanistic insight into framework evolution and provides a foundation for designing more time- and energy-efficient hydrothermal synthesis routes of zeolites.

水热合成是一种成熟的、可扩展的生产有序沸石的途径，是工业催化、分离和吸附的基础。然而，在高温下同时发生的化学缩聚和结构重组使得阐明非晶态前驱体如何形成框架秩序和连接变得困难，这阻碍了合理设计具有定制结构和催化性能的沸石。在这里，我们采用了一种时间分辨、多模式的方法来跟踪硅石-1 （MFI）在180°C下缩短合成时间（1-5小时）的结晶。结果揭示了从短程有序到部分组织的预通道和预交叉点的顺序演变，这些预通道和预交叉点逐渐连接成一个连续的微孔框架。出乎意料的是，瞬态介孔作为结合水、硅烷醇基团和模板物种的临时储存库，介导冷凝和缺陷愈合，从而驱动预通道的组装并将其固结成稳定的交叉点。中孔和骨架生长之间的这种合作相互作用阐明了在结晶的早期阶段等级秩序是如何发展的。煅烧后，延长处理去除残留物质，打开孔隙网络，提高可及性，巩固成熟的MFI晶格。由此得到的整体的、时间解析的机制为框架演化提供了机制上的洞察，并为设计更省时、更节能的沸石水热合成路线提供了基础。
