Description:

Carbon dioxide (CO2) emissions are a major contributor to the climate change equation. To alleviate concerns of global warming, strategies to mitigate increase of CO2 levels in the atmosphere have to be developed. The most desirable approach is to convert the carbon dioxide to useful products in engineered processes. Photocatalytic reduction of CO2 into hydrocarbon fuels is a promising approach to recycle CO2 as a fuel feedstock by taking advantage of the readily available solar energy. This article reviews the basics of CO2 photoreduction mechanisms, limiting steps, possible strategies for the photoreduction efficiency enhancement, and the state-of-the-art photocatalytic systems for CO2 reduction. In particular, a comparison between different catalytic systems, including biological (plants and algae), inorganics (semiconductors), organics (molecular complexes), and hybrid (enzyme/semiconductors) systems is provided.

Purpose/Objective:

A review particle to communicate to the science community on advanced carbon photoreduction sciences
