The photoinduced electron transfer process occurring on the semiconductor surface is being extensively investigated as a sustainable technology that can utilize solar energy for various energy and environmental applications. Metal oxides such as TiO2, WO3, and Fe2O3 and polymeric carbon nitride that consist of earth-abundant elements are the most practical base materials for photoelectrochemical (PEC) and photocatalytic (PC) conversion systems. The interfacial engineering of the semiconductor electrodes and nanoparticles can optimize the photoconversion reactions of diverse characteristics (e.g., degradation of pollutants, production of solar fuels and chemicals). In this talk, the developments of PEC and PC systems for sustainable purposes will be introduced and discussed, which include the PEC synthesis of H2O2 through dioxygen reduction, photocatalytic air purification, photocatalytic denitrification, and PEC water treatment. The limitations and challenges in PEC and PC systems for sustainable environment applications will be discussed.
