Abstract

Photocatalytic conversion of CO₂ using ZnO semiconductor is an effective, simple, economical and attractive way of combating energy problems resulting from anthropogenic emissions of CO₂ i.e. greenhouse gases to the atmosphere. This article focuses on current advances in CO₂photoreduction by hydrothermal method. The fundamental photocatalytic CO₂ reduction system by photocatalysts especially ZnO has been explicated. The synthetic protocol of ZnO and its growth mechanism in alkaline solution is elaborated with specific illustration of defect chemistry and its influence on CO₂reduction activity and selectivity. Conclusively, brief challenges of its current state and future prospects were also discussed.
