Application of Self-assembly of Nanomaterials in Electrochemical Reduction of Carbon Dioxide

The rapid development of nanomaterial self-assembly technology has greatly favored the field of electrochemical CO2 reduction reaction (CO2RR) and allowed for better control of catalyst structure and composition. Various self-assembly methods, such as DNA-directed assembly, matrix-assisted technology and solvent evaporation, have been used to improve catalytic efficiency and selectivity. Various newly created self-assembled catalysts have also contributed to the development of CO2RR, such as metal oxide catalysts, organic polymers and frameworks, organometallic frameworks and hybrid systems. This paper explored the application of the self-assembled nanocatalysts in CO2RR through a literature review and case studies, with an emphasis on how these methods can reduce CO2 to valuable products such as CO, methane and C2 compounds. The main results highlight the impact of self-assembled structures on improving reaction kinetics and product selectivity. The paper finds that self-assembly technologies and self-assembly nanocatalysts offer potential breakthroughs in improving CO reduction efficiency and contribute to the development of carbon capture and conversion technologies.
