Abstract
Photocatalytic reduction of carbon dioxide (CO ) is a promising technology for carbon recycling that offers both
2
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 CO in recent years, a systematic and comparative overview
2
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 CO reduction performance. Moreover, this review
2
highlights the challenges and opportunities in this field based on the current development trends.
