- CO2 is one of the major chemicals to cause the global warming and stored in an
atmosphere because its natural circulation to the carbohydrates by the photosynthesis
cannot come up with its excess production by the rapid development of industry.
Photochemical reduction of CO2 seems to be one of the ideal methods to artificially
circulate CO2 to its reduced forms, such as carbohydrates, because it mimics the natural
photosynthesis only with solar energy. We studied the photochemical reduction of CO2
using various photocatalysts and attempted to elucidate the conversion of CO2 to its
reduced forms of C1 chemicals, such as methanol, formic acid, methane, carbon
monoxide, and form acetate. The catalytic activity was measured with GC using the
liquid and gas phase products of CO2 reduction, which has been further investigated
using catalyst characterization methods of XRD, TEM, XPS, and UV-Vis.
