PURPOSE:To enhance the efficiency of light irradiation and reduce pressure loss by preparing a catalyst structure having three dimensional network through which reaction gas and light are passable and capable of carrying out a photocatalytical function by passing the reaction gas therethrough with the simultaneous light irradiation. CONSTITUTION:A photocatalytically active component is deposited on a carrier having three dimensional network structure through which reaction gas and light are passable to thereby prepare a catalyst structure. In the preferred embodiment, metal, ceramics and carbon may be used as the carrier and active carbon and photocatalytically active component may be deposited on such carrier. By way of example, the photocatalytically active component may be as follows; the oxides of Ti, Cu, Zn, La, Mo, V, Sr, Ba, Ce, Sn, Fe, and W and precious metals. Preferably, the porocity of the catalyst structure is not less than 75% and the photocatalytically active component may alternatively be of three dimensional network structure instead of using the carrier. |
