Research progress on reaction pathways and catalysts for CO2 hydrogentation to chemicals

This paper systematically reviews the research progress on the hydrogenation of CO2 to prepare methanol， formic acid， multi-carbon （C2+） alcohols， low-carbon olefins， aromatics and aviationkerosene， focusing on the core paradigms of reaction pathways （methanol-mediated pathway， Fischer-Tropsch synthesis pathway and direct conversion pathway） and the innovation of catalyst systems.

The catalyst system shows a multi-type coordinated development feature， covering single-function catalysts such as copper-based， indium-based， precious metal， solid solution， and bimetallic， as well as multi-function systems such as metal oxide-molecular sieve composites and tandem catalysis. Through the regulation of active components，the addition of additives，the functionalization of carriers，and structural optimization （such as single-atom and core-shellstructures）， achieve precise matching of the characteristics of active sites and structure-activity relationships， and promote continuous breakthroughs in catalytic performance.
