Description
前記(CaBa)TiO3に含まれるCaとBaの合計モル量に対するBaのモル量の比Ba/(Ca+Ba)が0.2より大きく、かつ、0.8未満であることを特徴とする。
TiO2、CaCO3、および、BaCO3の原料粉を所望の組成比で調合し、ボールミルで5時間撹拌して乾燥させた後、1100℃で仮焼することによって、セラミック粉体を得た。得られたセラミック粉体を硝酸Ni水溶液に浸漬して撹拌した後、150℃に設定したホットプレートで加熱して乾燥物を得た。その後、乾燥物を、大気中500℃で熱処理することによって硝酸を揮発させた後、水素中800℃で還元することにより、助触媒であるNiを1重量%担持させた(CaBa)TiO3粉からなる光触媒を作製した。
