Photoelectrochemical reduction of carbon dioxide to methanol on p-type CuFe2O4 under visible light irradiation

Artificial photosynthesis has the potential to produce solar fuels from CO2 and H2O using an efficient photocatalyst. Semiconductor with low band gap and high stability is always the right candidate to be used as photocatalyst. Photocatalytic (PC) reduction of CO2 suffers from slow reaction kinetics...
