本项目针对分子氧选择氧化有机醇制醛反应中分子氧利用率低等问题，拟构建一类对分子氧吸附和活化有高性能的钙钛矿基催化剂并研究其作用机理。首先，将模型钙钛矿（如：LaCoO3）与其他物相（如：LaFeO3）进行耦合，利用其他物相的性能优势来弥补模型钙钛矿某些性能（如：氧化或还原能力、氧空位含量等）的不足，提升其活化分子氧的效率；其次，在耦合钙钛矿纳米颗粒堆积孔中填充多孔材料（炭材料、介孔硅等），利用多孔材料的高比表面积、大孔容及孔道结构，提升钙钛矿对分子氧的吸附效率；然后，在分子氧吸附与活化效率提高的基础上，调控多孔材料与耦合钙钛矿的结构和组成，匹配分子氧的吸附与活化效率，获得对反应有高性能的钙钛矿基催化剂；最后，研究各物相间的协同作用机制、分子氧和有机醇的反应路线、并借助理论模拟计算，提出合理的反应机理，为今后高性能钙钛矿基催化剂的研发提供理论和技术指导。

This project aims to develop highly efficient perovskite-based catalysts, to solve the problem of low-efficient utilization of molecular oxygen in the aerobic selective oxidation of alcohols to aldehydes reaction, together with the investigation of reaction mechanism. First, coupled perovskites will be prepared through coupling with other phases (e.g., LaFeO3), which have the abilities to compensate the deficiency of the model perovskite (e.g., LaCoO3), to improve the efficiency of perovskite to activate the molecular oxygen. Second, porous materials (e.g., carbon, silica) with high surface area, large pore volume and specialized pore structure are to be filled in the pores made between the particles of the coupled perovskites, to improve the adsorption efficiency between the molecular oxygen to the perovskites. Third, the structure and component of porous materials and coupled perovskites will be tuned, so that the efficiency of perovskites to absorb the molecular oxygen matches the efficiency to convert the molecular oxygen, therefore achieving high-performance compound perovskite catalysts for the reaction. Finally, the reaction mechanism will be proposed, through investigating the synergistic effects between the phases, the reaction route between the molecular oxygen and the alcohols and with the aid of theoretical modeling and calculation, in order to provide theoretical directions for the design of high-performance perovskite catalysts for aerobic oxidation of alcohols in future.
