摘要

Photo/electrocatalytic CO2 reduction reaction (CO2RR) to valuable products represents a promising strategy for addressing environmental challenges and the global energy crisis. Owing to their intrinsic structural isotropy, high structural flexibility, fast ion transport capability, tunable electronic structures, and optimized reaction pathways, amorphous nanomaterials have emerged as highly attractive catalysts for CO2RR. Unlike previous reviews that mainly focus on amorphous electrocatalysts or specific material classes, this article provides a comprehensive overview of amorphous nanomaterials for both photo/electrocatalytic CO2RR. We first summarize recent advances in amorphous nanomaterials for both photo/electrocatalytic CO2RR, covering design principles, catalytic performance, and reaction mechanisms. Then, we correlate the amorphous structural features with CO2RR performance by examining three key aspects of the reaction pathway, including CO2 adsorption, CO2 activation and C–C/N coupling. Finally, current challenges and future research opportunities are discussed to provide guidance for the rational design of next-generation amorphous CO2RR catalysts.
