CO₂ emissions are regarded as one of the main causes of global warming by the greenhouse effect. Numerous attempts have been carried out for CO₂ capture and storage, but the eventual resolution may be the direct use of CO₂ as a component of useful materials.
Therefore, the activation and reduction of CO₂ are the ultimate goals of CO₂ management. However, it is very difficult to overcome the activation energy barrier of C-O bond cleavage, and either high reaction temperature or large electrochemical potentials are often required. To this end, photocatalytic conversion seems to be a promising process under ambient conditions by harnessing solar energy, which makes it economical and environmentally benign.
