Morphology Optimization of Spinel Catalysts for High-Efficiency Photothermal Catalytic Upcycling of Polyethylene Terephthalate.

Thermocatalytic recycling of plastics is typically constrained by high energy input requirements, resulting in poor economic efficiency and necessitating the utilization of light power. Indeed, photothermal catalysis offers several advantages over traditional photocatalysis and enables more efficient use of light energy. In this study, unique octahedral spinel-structured cobalt manganese oxide (CoMnO) catalysts are prepared.

Lead-Free Halide Double Perovskite CsAgBiCl for HS Trace Detection at Room Temperature.

Hydrogen sulfide (HS) is an important respiratory biomarker of many diseases, and thus, developing HS gas sensors with low detection limits at low operating temperatures is essential for the early diagnosis of diseases in low-resource environments. Although lead halide perovskites have unique electronic and optical properties, the high toxicity of lead has prompted the development of alternative materials. In this study, CsAgBiCl was synthesized using a simple method.
