Ciprofloxacin Photodegradation

In article number 2400375, Alberto Vomiero, Elisa Moretti, and co-workers synthesize cerium containing-titania nano-octahedra from commercial titania which are tested as photocatalysts for the removal of ciprofloxacin, in aqueous solution under simulated solar light. The optimized Ce concentration leads to an 83% degradation of ciprofloxacin after 360 min under simulated solar light, demonstrating the effectiveness of the new photocatalyst.

PtCu Alloy Nanodendrites

In article number 2400272, Geoffrey I. N. Waterhouse, Jing Xu, and co-workers present an aqueous visible-light-driven system with fluorescein as the exited state photosensitizer, which upon light irradiation reduces Pt⁴⁺ and Cu²⁺ salts to generate PtCu alloy nanodendrites, resulting in in situ catalyzing hydrogen production. The PtCu alloy nanodendrites are collected in pure and used as the electrocatalyst, which exhibits impressive bifunctional electrocatalytic activity for nitrogen oxidation to nitrate and nitrite/nitrate reduction to ammonia.

Lignin Nanoparticles

In article number 2400102, using demethylated lignin nanoparticles as formaldehyde scavengers in urea-formaldehyde (UF) resins, Ali Dorieh, Elham H. Fini, and co-workers produce a green MDF with minimal formaldehyde emissions. Increasing concentrations of these nanoparticles in the UF adhesive significantly reduces formaldehyde emissions and thickness swelling of MDF composites. Importantly, this reduction does not compromise the physical-mechanical properties, which remain comparable to boards bonded with unmodified UF.

木质素纳米颗粒在文章编号 2400102 中，Ali Dorieh、Elham H. Fini 及其合作者使用脱甲基木质素纳米颗粒作为脲醛（UF）树脂中的甲醛清除剂，生产出了一种甲醛释放量极低的绿色中密度纤维板。提高这些纳米颗粒在 UF 粘合剂中的浓度可显著减少甲醛释放量和中密度纤维板复合材料的厚度膨胀。重要的是，这种降低并不会影响物理机械性能，其性能仍可与未改性 UF 粘合的板材相媲美。

V/S co-doped SnO₂ bimetal sulfur-oxides catalysts labeled as (Sn,V)_1-_x(S,O)_2-_y or (SnVSO) with heterovalent state and oxygen vacancy defect are prepared via a green and facile method. The presence of SnVSO in the heterovalent states of Sn⁴⁺/Sn²⁺ and V⁵⁺/V⁴⁺ facilitates the rapid transfer of the electrons. It improves the electronic charge lifetime, accelerating the efficiency of the catalytic reduction of pollutants. The V/S co-doped SnO₂ regulates the bandgap energy structure. The hydrazine adjusts the heterovalent metal states to reduce Sn⁴⁺ to Sn²⁺ and V⁵⁺ to V⁴⁺. Also, it introduces oxygen vacancies to SnVSO to maintain the charge equilibrium and increase the active surface reactive sites, which enhance the catalytic activity. The SnVSO-3 prepared with 0.4 mL hydrazine exhibits excellent catalytic activity, which wholly reduces 20 ppm of 100 mL methyl orange (MO), rhodamine B (RhB), methylene blue (MB), hexavalent chromium (Cr⁶⁺), and 4-nitrophenol (4-NP) within 6 min. In addition, the SnVSO-3 also has good stability after repeated 6 runs with a reduction efficiency of 96.8%. Therefore, the V/S co-doped SnO₂ sulfur oxide catalysts have a promising potential for reducing Cr⁶⁺ and organic pollutants.

通过一种绿色、简便的方法制备了具有异价态和氧空位缺陷的 V/S 共掺杂 SnO2 双金属硫氧化物催化剂，标记为 (Sn,V)1-x(S,O)2-y 或 (SnVSO)。SnVSO 在 Sn4+/Sn2+ 和 V5+/V4+ 的异价态中的存在促进了电子的快速转移。它提高了电子电荷的寿命，加快了催化还原污染物的效率。V/S 共掺杂 SnO2 调节了带隙能结构。肼调整异价金属态，将 Sn4+ 还原为 Sn2+，将 V5+ 还原为 V4+。同时，肼还为 SnVSO 引入了氧空位，以维持电荷平衡并增加活性表面活性位点，从而提高催化活性。用 0.4 mL 联氨制备的 SnVSO-3 表现出卓越的催化活性，可在 6 分钟内完全还原 20 ppm 的 100 mL 甲基橙 (MO)、罗丹明 B (RhB)、亚甲基蓝 (MB)、六价铬 (Cr6+) 和 4-硝基苯酚 (4-NP)。此外，SnVSO-3 在反复运行 6 次后也具有良好的稳定性，还原效率高达 96.8%。因此，V/S 共掺杂 SnO2 氧化硫催化剂在还原 Cr6+ 和有机污染物方面具有广阔的前景。

The potential of a biodegradable polylactic acid (PLA)-TiO₂ membrane for air purification is investigated, utilizing the environmentally friendly solvent Cyrene. Through the integration of TiO₂ nanoparticles within a PLA matrix, the membrane is used to degrade ethanol as a model volatile organic compound (VOC) under UV light. Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDX), and UV–vis spectrophotometry confirm the porous structure of the membrane, the even distribution of TiO_2, and its effective band gap of 3.06 eV, respectively. Ethanol adsorption is best described by the Langmuir isotherm model, suggesting monolayer coverage on a homogeneous surface. Photocatalytic tests demonstrate that the membrane decomposes ethanol (6800 ppm) within 14 min under UV light, generating acetaldehyde, acetic acid, formaldehyde, and formic acid as intermediates, and ultimately producing CO₂ and water. Reusability tests indicate a decrease in decomposition time over successive cycles due to increased TiO₂ exposure from the gradual degradation of PLA. However, this degradation poses challenges for continuous use, compromising the membrane's long-term durability.

本研究利用环保型溶剂烯丙基（Cyrene）研究了可生物降解的聚乳酸（PLA）-二氧化钛膜在空气净化方面的潜力。通过在聚乳酸基质中整合 TiO2 纳米颗粒，该膜可在紫外光下降解乙醇这种典型的挥发性有机化合物（VOC）。扫描电子显微镜（SEM）、能量色散 X 射线分析（EDX）和紫外-可见分光光度法分别证实了膜的多孔结构、TiO2 的均匀分布及其 3.06 eV 的有效带隙。乙醇吸附用 Langmuir 等温线模型进行了最好的描述，表明在均匀的表面上存在单层覆盖。光催化测试表明，在紫外线照射下，该膜可在 14 分钟内分解乙醇（6800 ppm），生成乙醛、乙酸、甲醛和甲酸等中间产物，并最终生成二氧化碳和水。可重复使用性测试表明，由于聚乳酸的逐渐降解增加了二氧化钛的暴露量，在连续循环中分解时间缩短。然而，这种降解对连续使用提出了挑战，影响了膜的长期耐久性。

Lithium-oxygen (Li-O₂) battery is considered a high-energy alternative to Li-ion one due its characteristic electrochemical conversion process, with the additional advantage of lower cost and environmental impact. However, this emerging battery still requires an enhancement of stability and lifespan to allow its use as a practical energy storage system. In this work we investigate an electrode material benefitting of multiwalled carbon nanotubes (MWCNTs), few layer graphene (FLG), and gold nano-powder catalyst to improve the Li-O₂ battery performances in terms of energy efficiency, cycle life and stability. Morphological, structural, and electrochemical tests indicate that the composite electrode can actually boost the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), and enhance the Li-O₂ process reversibility, with a capacity of 1000 mAh g⁻¹ over 70 cycles. On the other hand, the tests reveal the role of the gold in decreasing the polarization and increasing the cell life. Therefore, the results suggest the combination of carbons with various morphologies as a suitable architecture for hosting the Li-O₂ reaction products and allowing their reversible reaction. On the other hand, the results highlight the necessity for a better tuning the noble metal characteristics to further enhance the cell performances.

锂-氧（Li-O2）电池因其特有的电化学转换过程而被认为是锂离子电池的高能替代品，同时还具有成本低、对环境影响小的优点。然而，这种新兴电池仍需要提高稳定性和寿命，才能作为实用的储能系统使用。在这项工作中，我们研究了一种由多壁碳纳米管（MWCNTs）、少层石墨烯（FLG）和纳米金粉催化剂组成的电极材料，以提高锂-O2 电池在能量效率、循环寿命和稳定性方面的性能。形态、结构和电化学测试表明，该复合电极实际上可以促进氧还原反应（ORR）和氧进化反应（OER），并提高锂-O2 过程的可逆性，在 70 次循环中可获得 1000 mAh g-1 的容量。另一方面，测试还揭示了金在降低极化和延长电池寿命方面的作用。因此，研究结果表明，将具有不同形态的碳结合在一起是一种合适的结构，可以容纳锂-O2 反应产物并使其发生可逆反应。另一方面，研究结果也强调了更好地调整贵金属特性以进一步提高电池性能的必要性。

Piezocatalysis has emerged as a promising field of research that uses mechanical energy to drive a chemical change. There is growing evidence that piezocatalysts can perform challenging chemical conversions from organic transformations to water splitting. A key challenge to piezocatlaysis is mitigating the inherent high relative permittivity of a ferroelectric material. This high permittivity restricts the transfer of carriers required for a chemical reaction to occur and reduces the reaction rate. Here the concept of producing a co-catalyst system is taken to enhance carrier mobility increasing the observed reaction rate. The study highlights the importance of determining the sonochemical and piezocatalytic contributions to catalysis. The combination of a Pt metal co-catalyst with BaTiO₃ through a simple solid-state method led to a four fold increase in the rate of H₂ production compared to BaTiO₃ and sonochemical reactions in the absence of a catalyst. BaTiO₃/Pt is found to exhibit stable piezocatalytic performance over 12 h. Where there is a deviation from steady-state water splitting, it is shown that this is due to mechanical removal of Pt rather than a phase change in the catalyst system. This work confirms the additive benefits of hybrid materials for improving piezocatalytic processes.

压电催化已成为一个前景广阔的研究领域，它利用机械能驱动化学变化。越来越多的证据表明，压电催化剂可以实现从有机物转化到水分离等具有挑战性的化学转化。压电催化剂面临的一个关键挑战是如何降低铁电材料固有的高相对介电常数。这种高介电常数限制了发生化学反应所需的载流子传输，降低了反应速率。这里采用了生产辅助催化剂系统的概念来提高载流子的流动性，从而提高观察到的反应速率。这项研究强调了确定声化学催化和压电催化对催化的贡献的重要性。通过一种简单的固态方法将铂金属助催化剂与 BaTiO3 结合在一起，与 BaTiO3 和没有催化剂的声化学反应相比，产生 H2 的速率提高了四倍。研究发现，BaTiO3/Pt 在 12 小时内表现出稳定的压电催化性能。在出现偏离稳态水分离的地方，研究表明这是由于铂的机械去除而不是催化剂系统中的相变造成的。这项研究证实了混合材料在改善压电催化过程方面的附加效益。
