Photoelectrochemical (PEC) reduction of CO2 is a potential way to simultaneously address environmental problems and reduce the energy crisis. However, traditional conversion of CO2 in aqueous solution has serious drawbacks, such as low solubility, slow diffusion, and complicated existing form of CO2...
