Photocatalysis plays a key role in CO preferential oxidation (CO-PROX) in H-2-rich streams thanks to the great performance this reaction can achieve when it is light driven, at atmospheric pressure and room temperature, with negligible hydrogen loss. This short review is an attempt to summarize the most recent advances in photo-PROX focused mainly on the most popular strategies to improve TiO2 photocatalytic activity, as well as on the active phases used, paying special attention to the synthesis and deposition of noble metal nanoparticles because of their outstanding properties. In this work, we critically review these results with the aim of finding general indications about the main characteristics of the catalysts and the optimal operating conditions of photo-assisted CO-PROX reaction..
