This method is usually one in which UV light is irradiated while CO 2 is blown into an aqueous solution in which photocatalyst fine particles are suspended, and there are the following problems. It is difficult to separate the catalyst after the reaction, and TiO 2 cannot use sunlight due to its own band gap characteristic.

The immobilization method is mainly conversion to methanol. here,
To achieve a high CO 2 immobilization rate using sunlight,
Although it is essential to develop a photocatalyst that can be excited by the energy of sunlight and to have high selectivity for the product, the conventional method has the following drawbacks. (1) Since titanium oxide is used as a photocatalyst, sunlight cannot be used, and the photofixation reaction proceeds only by high-energy ultraviolet light. (2) In the photocatalytic reaction utilizing ultraviolet light, the decomposition reaction of the product proceeds, and the apparent reaction rate of the immobilization reaction is low.

炭化水素（メタノール、エタノール）が生成する。The visible light excitation type semiconductor used in the present invention includes SiC, CdS, GaP and the like which are excited by light having energy lower than the ultraviolet light region. Also,
Quartz glass is generally used as the light-transmissive base material, and the shape thereof may be any shape such as a plate shape, a bead shape, and a fiber shape. The thinner the visible light excited semiconductor supported on the light transmissive substrate, the higher the catalytic activity. (Quantum size effect) Therefore, the supported thickness should be a molecular thickness of a single molecule to a few molecules. In order to improve the activity of the photocatalyst (visible light excitation type semiconductor), it is necessary to make the particles finer or thinner as described above, but there is a limit to making the semiconductor finer or thinner and the handling becomes difficult. However, it is relatively easy to form a thin film of a semiconductor on the surface of the light transmissive base material, and the handling becomes good. (Scattering of fine particles and the like can be avoided) In addition, by supporting the semiconductor on the light transmissive base material in this way, the separation of the photocatalyst after fixation of carbon dioxide becomes easy. The base material for supporting the semiconductor is sufficient if it is light transmissive, but if it is more porous, the geometric area on which the photocatalyst is supported is increased, which is particularly preferable. When carbon dioxide and water are brought into contact with the above-described photocatalyst under sunlight irradiation, the semiconductor of the photocatalyst is excited by the sunlight to exert its catalytic ability, and oxygen-containing hydrocarbon (methanol, ethanol) is generated.
