Photocatalytic CO2 conversion is the conversion of CO2 and water into oxygen and liquid fuel using solar light as an energy source, mimicking the natural photosynthesis reaction. Inorganic materials that convert energy from solar energy into chemical energy is called a photocatalyst, and the photocatalyst absorbs light energy to form excited electrons in the catalyst, and this electron reduces the CO2. In this study, we synthesized ordered mesoporous photocatalysts which have different classes with respect to the dimension of pore ordering using different synthesis conditions. As a result, we could found that these ordered photocatalysts could convert CO2 to high value-added products in the presence of water and solar light.
