Abstract

In recent years, the rapid consumption of fossil fuels has brought about the energy crisis and excess CO 2 emission, causing a series of environmental problems. Photocatalytic CO 2 reduction technology can realize CO 2 emission reduction and fuel regeneration, which alleviates the energy crisis and environmental problems. As the most widely used LDH material in commercial application, MgAl-layered double hydroxide (MgAl-LDH) already dominates large-scale production lines and has the potential to be popularized in CO 2 photoreduction. The adjustable component, excellent CO 2 adsorption performance, and unique layer structure of MgAl-LDH bring specific advantages in CO 2 photoreduction. This review briefly introduces the theory and reaction process of CO 2 photocatalytic reduction, and summarizes the features and drawbacks of MgAl-LDH. The modification strategies to overcome the drawbacks and improve photocatalytic activity for MgAl-LDH are elaborated in detail and the development perspectives of MgAl-LDH in the field of CO 2 photoreduction are highlighted to provide a guidance for future exploration.
