Research progress in the construction of integrated catalysts based on solid precursors and their application in CO2 hydrogenation
To overcome the problems of uncontrollable active sites and microstructures of catalysts,the utilization of solid precursor as a controlled-release source of metal ions has emerged as a promising approach for fabricating metal-based integrated catalysts with precise microstructures and well-defined spatial configuration of active sites,therefore realizing the rational design of catalysts.This review highlights four types of solid precursor materials,namely transition metal phyllosilicates,layered double hydroxides,metal-organic frameworks,and bismuth vanadate materials,for the preparation of catalysts for thermal catalytic hydrogenation of CO2.The review provides an overview of preparation mechanisms and application examples of these four integrated catalyst materials,along with an outlook on the research direction of developing multi-component integrated catalysts based on solid precursors.
