Photocatalytic conversion of CO2 into value-added and renewable fuels

Artificial photosynthesis that uses solar light energy to convert CO2 to form value-added and renewable fuels is considered to be a promising avenue to solve the problems relating to CO2. However, the state-of-the-art photocatalytic efficiency of CO2 reduction is far from being optimal as a viable economical process. The present review is mainly focused on the progress made in exploring more efficient photocatalysts for CO2 photoreduction and the undergoing mechanisms, which is anticipated to contribute to further advancement in CO2 photoreduction with on-going efforts.
