Perovskite materials are regarded as promising photocatalysts for light harvesting, yet they exhibit low photocatalytic activity due to serious charge recombination and lack of efficient catalytic sites toward CO2 reduction. Previous studies have employed perovskites reductive sides in a Z-scheme heterojunction suppress recombination, which however still encounter selectivity because the absence specific In this work, we report strategy that enables CsPbBr3 perovskite methanation. The central concept is construction using zinc phthalocyanine (ZnPc) side. enhanced separation CsPbBr3/ZnPc provides catalytically active ZnPc with sufficient energetic electrons As result, achieves up 89% 168 μmol g–1 h–1 CH4 production, well exceeding all reported perovskite-based photocatalysts. This work insights into rational design heterojunctions artificial photosynthesis.

The excessive consumption of fossil fuels increases CO2 emissions, and the consequent greenhouse effect resulting from higher levels this gas in atmosphere has a significant impact on environment climate. This necessitated development environmentally friendly efficient methods for conversion. carbon dioxide electroreduction reaction (CO2RR), which is driven by electricity generated renewable energy sources (e.g., wind solar) to convert into value-added or chemicals, regarded as promising prospective path toward cycling. Among various products, formate, with its relatively simple preparation process, broad application prospects, can be used fuel, hydrogen storage material, raw material downstream chemicals. Sn-based oxide electrocatalysts have advantages being inexpensive nontoxic. In addition, these catalysts offer high product selectivity are electrochemical reduction formate. review, we first clarify mechanisms factors that influence then provide some examples technologies could study evolution during reaction. particular, focus traditional oxides (SnO2) novel perovskite been developed use field CO2RR recent years considering their synthesis, catalytic performance, optimization strategies, intrinsic principles. Finally, current challenges opportunities discussed. perspectives latest trends presented review expected inspire researchers contribute more efforts comprehensively optimizing performance produce
