To integrate high chromaticity with visible-light-driven antibacterial functionality in yellow inorganic pigments, carbon-doped BiVO4 (C-BiVO4) pigments were synthesized via a one-step self-propagating combustion synthesis (SCS) using citric acid as a fuel and carbon source. The effects of citric acid dosage on phase composition, morphology, chromatic performance, and antibacterial activity were systematically investigated. The results indicate that carbon doping induces lattice expansion and oxygen vacancy formation, modulates the electronic band structure, and significantly suppresses photogenerated electron-hole recombination. At an optimal citric acid to BiVO4 molar ratio of 1.2, the pigment exhibits excellent yellow chromaticity (b* = 79.71). Under visible-light irradiation, C-BiVO4 achieves a methylene blue photodegradation rate of 96.63% and an E. coli inactivation efficiency of 99.99%, substantially outperforming undoped BiVO4. Moreover, the C-BiVO4 yellow pigment shows good dispersibility and thermal stability in PMMA and glass matrices and passes acute skin irritation and dermal toxicity tests, confirming its low toxicity and non-irritating nature. This work provides a new strategy for developing environmentally friendly inorganic pigments that combine high chromaticity with photocatalytic antibacterial functionality. Full article

Cs3Cu2I5 single crystals are regarded as promising next-generation scintillators due to their large Stokes shift and low self-absorption characteristics. However, the cost-effective solution growth method faces critical challenges: the instability of colloidal precursors in solutions and the severe oxidation of Cu+ during crystal growth. This study innovatively introduces yttrium chloride (YCl3) as a dual-functional additive to address both issues simultaneously. The hydrolysis of YCl3 creates a controlled acidic environment, effectively suppressing the oxidation of Cu+; meanwhile, it enhances the stability of colloidal precursors by significantly increasing their surface charge and narrowing the particle size distribution. These synergistic effects enable the rapid growth (approximately 100 h) of near-centimeter-sized Cs3Cu2I5 single crystals with high crystallinity, without the need for inert gas protection. The optimized crystals exhibit exceptional performance: a photoluminescence quantum yield (PLQY) of 93.22% ± 0.47%, a scintillation decay time of 210.04 ns, and a light yield of ~738.14 pe/MeV. This YCl3-mediated growth strategy establishes an efficient approach for the solution-based synthesis of high-quality Cs3Cu2I5 single crystals, holding great significance for advancing high-sensitivity, environment-stable radiation detection applications such as medical diagnostics and nuclear safety monitoring.

The poor stability of CsPbBr3 perovskite nanocrystals (PNCs) caused by weak and dynamic ligand coordination severely limits their commercial applications. Herein, a dual-ligand synergistic modification strategy based on bromocarboxylic acids (BCAs) and oleylamine (OAm) was developed to mediate the surface structures and luminescent dynamics of CsPbBr3 PNCs. The results reveal that carboxylate groups of BCA ligands modulate crystal growth, while its terminal Br atom forms a strong coordination with exposed Pb2+ on the PNCs surface, which can effectively passivate lead- and bromine-related defects. The synergistic protection of OAm ligands enhances the stability of PNCs via amino-halide electrostatic interactions and steric hindrance effects. Notably, based on the relatively dense surface coating of 4-bromobutyric acid (BBA) and OAm dual-ligands, the prepared CsPbBr3 PNCs exhibit a high photoluminescence quantum yield (PLQY) of 85.2 ± 2.4% and remarkable storage stability, retaining 90.2 ± 1.7% of their initial PL intensity after being stored for 63 days under ambient conditions. Furthermore, a prototype white light-emitting diode (WLED) fabricated with these PNCs displays a wide color gamut covering 122.1% of the NTSC standard and a luminous efficacy of 64.6 lm/W. This work provides a facile and feasible ligand engineering strategy to obtain highly stable and emissive PNCs. Full article

Fuel cells are regarded as highly promising energy devices due to their clean and efficient energy conversion characteristics. However, their core material, platinum-based catalysts face challenges such as high cost, resource scarcity, and the high energy consumption and pollution associated with traditional synthesis methods, which contradict the green development principles of fuel cell technology. The rise of green chemistry provides a new research direction for developing environmentally friendly and cost-effective catalyst preparation routes. This review systematically summarizes recent research progress in the green synthesis of platinum-based catalysts for fuel cells, focusing on four core strategies: green solvent systems, biological reduction systems, renewable resource templates, and green energy-saving methods. It provides a detailed analysis of the principles of each method and their regulatory mechanisms on the microstructure. More importantly, this review elucidates the effects of size, morphology, and surface state on catalytic performance and establishes a structure–activity relationship linking green synthesis methods, microstructure, and catalytic performance and further discusses the regulatory mechanisms of catalyst structure, operating temperature, and electrolyte environment on electrochemical kinetic behavior. Furthermore, this article critically evaluates the advantages, limitations, and industrialization challenges of various green technologies. This review provides an important reference for the preparation and industrial application of high-performance, low-platinum, and environmentally friendly fuel cell catalysts. Full article

Lithium-ion batteries (LIBs) face the safety hazard of thermal runaway (TR). Gas-sensing-based monitoring is one of the viable warning approaches for batteries during operation, and TR warning using semiconductor gas sensors has garnered widespread attention. This review presents a comprehensive analysis of the latest advances in this field. It details the gas release characteristics during the TR failure process and identifies H2, electrolyte vapor, CO, CO2, and CH4 as effective TR warning markers. The core of this review lies in an in-depth critical analysis of gas-sensing materials designed for these target gases, systematically summarizing the design, performance, and application research of semiconductor gas-sensing materials for each aforementioned gas in battery monitoring. We further summarize the current challenges of this technology and provide an outlook on future development directions of gas-sensing materials, including improved selectivity, integration, and intelligent advancement. This review aims to provide a roadmap that directs the rational design of next-generation sensing materials and fast-tracks the implementation of gas-sensing technology for enhanced battery safety.
