Tailoring ultra-small ZnO nanoparticles through cobalt doping to enhance photocatalytic CO₂ reduction.

ABSTRACT: Photocatalytic CO₂ reduction offers a promising pathway for achieving sustainable development. However, the effectiveness of this method faces challenges related to imbalanced charge transfer/utilization. To address these issues, this paper reports on cobalt-doped zinc oxide nanoparticles (Co-ZnO NPs). The cobalt doping not only increases light absorption but also improves charge transfer/separation kinetics and modulates the reduction reaction dynamics. Notably, photocatalytic tests show that cobalt-doped zinc oxide (Co-ZnO) achieves a CO yield of 143.90 μmol g^-1 h^-1, which is 15.73 times higher than that of undoped ZnO, and exhibits excellent stability. This study emphasizes the importance of polarization states induced by doping for achieving efficient c
