Recent developments in metal nanocluster-based catalysts for improving photocatalytic CO2 reduction performance

Abstract

Photocatalytic reduction of carbon dioxide (CO2) is a promising technology for carbon recycling that offers both environmental and economic benefits. Among the potential photocatalysts, metal nanoclusters (MNCs) stand out as a class of materials with remarkable photophysical and photochemical properties. Despite the growing number of studies on MNCs-based photocatalytic reduction of CO2 in recent years, a systematic and comparative overview of these studies is still lacking. This review provides a concise and comprehensive summary of the latest research on MNCs-based catalysts for enhancing photocatalytic CO2 reduction performance. Moreover, this review highlights the challenges and opportunities in this field based on the current development trends.
