Defect‐Rich Ultrathin ZnAl‐Layered Double Hydroxide Nanosheets for Efficient Photoreduction of CO₂ to CO with Water

Abstract

Defect-rich ultrathin ZnAl-layered double hydroxide nanosheets are successfully prepared. Under UV-vis irradiation, these nanosheets are superior efficient catalysts for the photoreduction of CO2 to CO with water. The formed oxygen vacancies lead to the formation of coordinatively unsaturated Zn(+) centers within the nanosheets, responsible for the very high photocatalytic activities.
