Artificial Photosynthesis for Value-Added Chemicals Production

Solar energy utilization has been drawn attention due to the environmental issues. Photoelectrochemical and photocatalytic water splitting for hydrogen production, which is well-known solar-to-chemical process, have been studied so far, however it is now facing limitations of efficiency along with affordable cost. Recently, research trends in artificial photosynthesis are changing their redox reaction to produce value-added chemicals. Thanks to the previously studied solar water splitting technologies and materials, value-added chemicals production by solar energy is now evolving rapidly by taking advantages from the established works. Here, we introduce various kinds of redox reactions for producing value-added chemicals via photoelectrochemical and photocatalytic process. Throughout the article, solar-driven redox reactions such as CO 2 reduction, H 2 O 2 production are comprehensively discussed from the fundamentals to the applications. Consequently, future perspectives are suggested, which may help put forward future commercialization of photoelectrochemical or photocatalytic value-added chemical production technologies.
