RESEARCH PROGRESS ON BIFUNCTIONAL CATALYSTS FOR DIRECT HYDROGENATION OF CO2 TO AROMATICS

Abstract

Abstract: Research on bifunctional catalysts for direct hydrogenation of CO₂ to aromatics provides a new approach for exploring the synthesis of aromatics using CO₂ as a carbon source, which is conducive to promoting the low-carbon emission reduction and green transformation of the chemical industry. This work focuses on the design and performance optimization of bifunctional catalysts aimed at enhancing CO₂ conversion efficiency and aromatic selectivity through advanced catalytic material development. A systematic analysis is conducted on the synergistic mechanisms of the methanol-mediated and Fischer–Tropsch synthesis pathways, with particular emphasis on the influence of active site structure, pore architecture, and acid site distribution on reaction pathway regulation. Furthermore, the effects of key operational parameters, such as the metal-to-zeolite mass ratio and reaction temperatureon product distribution are elucidated. The study demonstrates that constructing bifunctional catalysts with spatial and acidic synergistic effects enables both efficient CO₂ conversion and selective aromatics formation. Future research directions will focus on the development of novel hierarchical pore-structured catalyst systems, dynamic mechanistic investigations, and integrated process optimization, providing technological support for CO₂ valorization.

Key words: hydrogenation of CO₂, aromatics, bifunctional catalyst
