摘要：
Provided is a method for preparing a photocatalyst, comprising the steps of: preparing a first porous metal oxide film formed from a first metal oxide by a sol-gel method crystallizing the first metal oxide by heat treating the first porous metal oxide film allowing ions of a second metal to penetrate into the inner pores of the first porous metal oxide film by dipping the first porous metal oxide film into a precursor solution of the second metal and irradiating light at the first porous metal oxide film and forming particles of the second metal in the inner pores of the first porous metal oxide film through the reduction of the ions of the second metal by dipping the first porous metal oxide film, which contains the ions of the second metal in the inner pores, into an alcohol solution and irradiating light at the first porous metal oxide film.本發明提供一種光催化劑的製備方法,其包括:根據溶膠-凝膠法,使由第一金屬氧化物形成的多孔性第一金屬氧化物膜成膜;對該多孔性第一金屬氧化物膜進行熱處理,來使該第一金屬氧化物結晶化;將該多孔性第一金屬氧化物膜浸漬於第二金屬的前驅體溶液之後進行光照射,使該第二金屬的離子滲透於該多孔性第一金屬氧化物膜的內部空隙;以及將在內部空隙包含該第二金屬的離子的該多孔性第一金屬氧化物膜浸漬於酒精溶液之後進行光照射,使該第二金屬的離子還原,而在該多孔性第一金屬氧化物膜的內部空隙形成該第二金屬的粒子。
