Unreasonable tunnel structure and low intrinsic conductivity limit practical applications of niobium oxide in high-performance supercapacitors. The study reports the construction of NbVO electrode material via coordination of Nb(V) and V(V) with histidine and serine-functionalized and boron-doped graphene quantum dot (HSBGQD) and subsequent annealing. The introduction of HSBGQD and rambutan peel leads to formation of small NbVO nanocrystal and low valent Nb and V species. The combination of small size and more reasonable tunnel structure accelerates the ion diffusion. The Nb(IV) and V(IV) double doping optimizes the tunnel structure, narrows the bandgap and creates new pathways for high-speed electron transfer. The integration of defect engineering with graphene surface modification enhance the intrinsic conductivity. The NbVO electrode shows exceptionally high specific capacitance of 2925.3 F/g, which is more than 142 times that of NbO. The symmetrical supercapacitor with NbVO electrodes and PVA/LiSO gel electrolyte offers high specific capacitance (263 F/g at 1 A/g), high-rage capacity (138 F/g at 50 A/g), cycling stability (capacitance retention of 95.2 % after 10,000-cycle), energy density (146 W h Kg at 996 W Kg and 77 W h Kg at 50181 W kg) and broad application prospect in wearable electronic devices.

Various grades of manganese dioxide ores, as a natural recyclable sorbent, can be used in dry flue gas desulfurization (FGD) at moderate temperatures (350–450 °C). This research provided low- and high-grade manganese dioxide ores to examine SO removal in a packed bed reactor. To obtain characteristic parameters of mineral sorbents, XRD, XRF, BET, and mercury porosimetry were employed. Then, kinetic parameters of desulfurization reaction were determined using thermogravimeter analyzer (TGA) and random pore model (RPM) for a single pellet. In desulfurization experiments of simulated flue gas in a packed bed reactor and mass spectrometer (MS) apparatus, the breakthrough times were measured under various operating conditions. The onset of these breakthrough times or life-time of MnO reactor for the SO removal was predicted successfully by RPM for a packed bed reactor using related kinetic constants from TGA. In addition, reacted sorbets were recycled multiple times after washing with water. Not only does this simple method separate MnSO from unreacted sorbents as a valuable byproduct to reduce the FGD cost, but it also improves pore size distribution (PSD) of mineral MnO by creating large pores. Modified PSD of this recycled sorbent caused increased breakthrough time.

Solar-thermal materials enable the heating of reaction solutions in organic reactions without consuming fossil fuels or electricity. In this study, nanostructured polypyrole@Pd was utilized with solar-thermal, catalytic, and Pickering emulsifier functionalities to successfully demonstrate eco-friendly and scalable Suzuki coupling reactions. Pd-catalyzed multiphasic Suzuki coupling reactions were accelerated with high conversions through solar-thermal heating and the formation of Pickering emulsions in a phase-separated, highly concentrated reaction mixture using polypyrole@Pd. Increasing the interfacial area by forming a Pickering emulsion facilitates mass transfer between the two miscible liquid phases, which is crucial for multiphasic reactions. Gram-scale synthesis under solar illumination over an area of 3.14 cm was successfully achieved, and the multiple usability of polypyrrole@Pd was demonstrated over 20 cycles.

Mesophase pitch carbon fiber has shown remarkable prospects in specialty carbon material. The mechanical properties of mesophase pitch carbon fiber (CF) cannot be precisely controlled because of the difficulty of forming process regulation. The early forming of carbon fiber (precursor fiber (PF) and pre-oxidation fiber (OF)) is difficult to regulate, such as carbon microcrystal and carbon layer texture, while cause the irreversible growth of carbonization process. Herein, a synergy strategy of spinning drawing and preoxidation stretching is developed to optimize orientation structure, eliminate morphology defects and improve mechanical properties. A synergistic effect of superior spinning drawing and suitable preoxidation stretching is beneficial to adjust the more order rearrangement of carbon microcrystals. The tensile strength of carbon fibers with spinning drawing and preoxidation stretching is increased by 1.7 times, and their defects are reduced by 40%. The results show that the excellent mechanical property of carbon fiber is contributed by the extrusion stress caused by high oxidation crosslinked surface layer under tension, and the micro-flow and rearrangement of carbon microcrystals induced by extrusion stress. A mechanical strengthening mechanism of carbon fiber is proposed, which provides guidance for high-performance mesophase pitch carbon fiber.

Membrane fabrication via phase inversion depends on various influential parameters which may result in enhanced membrane performance. In this study, metal oxide nanoparticles i.e. FeO/ZnO were modified with glycine and diethylene glycol and then embedded onto polyethersulfone (PES) membranes to form PES/FeO/ZnO membranes. These membranes were used to remove manganese, copper, and lead ions from wastewater. Transmission electron microscope images confirmed that FeO/ZnO were composed of cubic and spherical morphologies. Fourier Transform Infrared spectra confirmed that FeO/ZnO nanoparticles were successfully modified using glycine and diethylene glycol. The surface and cross-sectional images showed that polyvinylpyrrolidone (PVP) and the coagulation bath temperature influenced the resulting membrane surface and confirmed the successful addition of nanocomposite concentrations (0.25, 0.50 and 0.75 wt%) onto PES membranes. The 0.50 wt% FeO/ZnO loaded membrane showed highest permeability with water flux of 682 L/m.h, and high flux recovery ratio (%) of 98.75 %, 88.88 % and 71.77 % for BSA, HA and wastewater samples, respectively, indicative of less prone to fouling. The chemical and mechanical enhancement through PVP concentration, coagulation bath temperature and nanoparticle loading significantly influenced the selectivity and fouling propensity of the PES membranes. Therefore, all parameters played a role in tuning the chemical and physical structure of the prepared membranes.

We developed a novel MXene/polymer hybrid material for enhanced photodegradation of multiple organic dyes. Specifically, uniform-sized PMMA microspheres and multilayer Ti3C2Tx MXene were integrated through a facile solution process to form PMMA/Ti3C2Tx composites. The hybridization of the two components significantly increased the specific surface area and pore volume. An optimized composite showed high photocatalytic activity, demonstrating 93 and 98 % degradation efficiencies for orange G (OG) and rhodamine B (RhB) in 60 min of light illumination. Furthermore, the composite revealed good recyclability without a significant performance drop even after four cycles. Moreover, the composite retained its high photocatalytic activity at various conditions, including elevated temperatures, a wide range of pH levels, and in tap water. These results manifest that the PMMA/Ti3C2Tx hetero-photocatalyst is well suited for use in wastewater treatment and environmental cleanup.

Water pollution due to organic pollutants poses a significant environmental threat, necessitating the development of effective materials for their complete removal. This study introduces a novel Z-scheme ZnFeO/MWCNT/BiOBr (ZMB) ternary composite to enhance the removal of brilliant green (BG) dye and tetracycline hydrochloride (TCH) antibiotic. The synthesized materials were comprehensively analyzed using a range of characterization techniques, including XRD, UV–Vis DRS, FTIR, SEM, TEM, EDX mapping, BET, and XPS. A series of ternary composite materials with varying percent mass ratios of ZnFeO was synthesized, of which the optimized 6ZMB composite (6 % mass ratio of ZnFeO) demonstrates the highest degradation rates for BG (99.9 %) and TCH (95.1 %) within 20 and 100 min, respectively. Trapping experiments confirmed that O• and •OH were the main reactive species responsible for the degradation of BG and TCH pollutants. The NBT transformation experiments and PL terephthalic acid probe method further confirmed the involvement of O• and •OH, respectively. Furthermore, the adsorption isotherm study showed that BG adsorption onto the 6ZMB ternary composite predominantly followed the Langmuir model, with a high regression coefficient (0.9963 and 0.9777 for linear and nonlinear fit, respectively), indicating effective and consistent adsorption through chemisorption.

Here, a hybrid mesoporous sheets-like nano-catalyst was used to investigate the degradation of Congo Red (CR) dye. The photocatalytic efficiency of CR dye degradation was evaluated using a variety of mesoporous hybrid materials containing P,S,N-doped carbon (PC1), CoO@P,S,N-doped carbon (PC2), NiO@P,S,N-doped carbon (PC3), and NiCoO@P,S,N-doped carbon (PC4) sheet-like. The results indicated that the PC4 nano-catalyst exhibited exceptional efficacy in the photocatalytic degradation of CR dye, achieving a degradation efficiency exceeding 99 %. The results also showed that PC4 possessed a band gap of 1.7 eV. To formulate an effective photodegradation system, Analysis of Variance (ANOVA), a valuable statistical method, was employed to examine how varying pH, PC dose, and irradiation time can improve the photodegradation performance. Influential key parameters, including pH, PC dose, irradiation time, and CR concentration, were optimized through response surface methodology applying a four-factor, three-level Box-Behnken design (BBD). To achieve a 99 % decolorization of CR, the optimum conditions were determined to be pH 3.8, PC dose at 14 mg, irradiation time of 10.2 min, and CR concentration of 14.3 ppm. Kinetic models demonstrated that CR degradation followed pseudo-first-order kinetics. Moreover, band gap comparisons, scavenger analysis, and density functional theory (DFT) were used to discuss the CR degradation mechanism.

Supercapacitors are high-performance electrochemical energy storage devices with high power density, long cycle life, and rapid charge and discharge capabilities. However, in the conventional electrode fabrication process, the addition of binders without conductivity and electrochemical activity reduces the mass of active materials and increases resistance in the electrode, which compromises its electrochemical performance. Therefore, the binder-free electrode is an effective method to enhance the electrochemical performance and energy density of electrodes. The different fabrication technologies for binder-free electrodes have been explored in detail, especially focusing on surface growth on current collectors, self-assembly techniques, and the new technological methods. The design of electrochemically active materials, including carbon, metal compounds, and conductive polymers have been emphasized, along with the optimization of processes and the enhancement of performance, interface engineering and improvements in electrode functionality, the utilization of multifunctional performance materials, and the design and optimization strategies grounded in theoretical simulations. Depending on the actual situation, binder-free electrodes can increase energy density and specific capacitance 10% to 30% approximately. Finally, the advantages of binder-free electrode technology in supercapacitors and other energy storage fields are introduced, further exploring future research directions and the potential breakthroughs and challenges that binder-free electrode technology may bring.

However, in the conventional electrode fabrication process, the addition of binders without conductivity and electrochemical activity reduces the mass of active materials and increases resistance in the electrode, which compromises its electrochemical performance. Therefore, the binder-free electrode is an effective method to enhance the electrochemical performance and energy density of electrodes. The different fabrication technologies for binder-free electrodes have been explored in detail, especially focusing on surface growth on current collectors, self-assembly techniques, and the new technological methods. The design of electrochemically active materials, including carbon, metal compounds, and conductive polymers have been emphasized, along with the optimization of processes and the enhancement of performance, interface engineering and improvements in electrode functionality, the utilization of multifunctional performance materials, and the design and optimization strategies grounded in theoretical simulations.

A wireless-integrated tumor microenvironment-responsive sensor designed from diselenide-functionalized carbon dot (dsCD) and hyaluronic acid polymer dot (PD(HA)) loaded in a mineralized conductive hydrogel (dsCD-PD(HA) Hydrogel) for detecting cellular reactive oxygen species (ROS) and pH detection. The manufactured ROS/pH responsive conductive hydrogel efficiently differentiated between cancer cells and normal cells in response to cellular factors through changes in fluorescence, electrical and mechanical response. Tumor microenvironment acidity and high ROS concentrations caused fluorescence recovery boronate ester and diselenide bond cleavage alongside a change in electrical resistivity from 78.9 kΩ (pH 7.4) to 38.8 kΩ (0.1 mM HO/pH 6.8) due to disintegration of molecular interaction in the sensor. In vitro electrochemical analysis revealed different ΔR/R bending profiles between cancer (26.2 % and 25.9 % for HeLa and PC-3, respectively) and normal cells (17.9 %), alongside the optical performance demonstrating higher regain of fluorescence of cancer cells (HeLa and PC-3) compared to the normal cells (CHO-K1). Additionally, the dsCD-PD(HA) Hydrogel demonstrated favorable biocompatibility and ROS scavenging, with selective targeting of cancer cells. A wireless sensing platform was developed by connecting the dsCD-PD(HA) Hydrogel sensor to a smartphone, showing a precise signal during detection resistance or electro-mechanical signals.
