Description
(A)平均粒子径0.8~2.0μmのコバルト酸化物粒子を、コバルトイオン生成可能な塩又は化合物、セリウムイオンを生成可能な塩又は化合物および水と混合して触媒浸漬液を調製する工程、
(B)得られた触媒浸漬液に炭化ケイ素(SiC)を主成分とする担体を浸漬処理する工程、及び
(C)浸漬処理後の担体を焼成する工程
を含む方法によって製造することができる。これにより、SiC担体に、触媒粒子(コバルト・セリウム系複合酸化物)が担持される。触媒粒子は、平均粒子径0.8~2.0μmのコバルト酸化物粒子のまわりがコバルトイオンを前駆体とするコバルト酸化物およびセリウムイオンを前駆体とするセリウム酸化物で覆われている。ここで平均粒子径は、レーザー回折法によって求めた粒度分布における積算値50%での粒径(d0.5)を意味する。また、「コバルト酸化物粒子のまわりがコバルト酸化物及びセリウム酸化物で覆われている」とは、コバルト酸化物粒子の表面にコバルト酸化物及びセリウム酸化物が形成されていることを意味する。したがって、触媒粒子は、平均粒子径0.8~2.0μmのコバルト酸化物粒子と、コバルトイオンを前駆体とするコバルト酸化物と、セリウムイオンを前駆体とするセリウム酸化物と、を有している。
触媒の製造方法は、本発明者らが創案した方法(特許文献2)を参考にした。具体的にはコバルト炭酸塩を空気中で300℃~500℃の範囲内の一定温度で5時間焼成した後、ジェットミル法にて粉砕を行った。粉砕後のコバルト酸化物に対して蒸留水、硝酸コバルト、硝酸セリウム等を加えてよく攪拌混合し、コバルト・セリウム系前駆体溶液を調製した。この前駆体溶液の貯留容器中にハニカム型のSiCセラミックス担体を1分間浸漬した後、エアブローし、空気中において500℃で1時間焼成することにより、コバルト・セリウム系複合酸化物を担持した担持触媒(以下、「Co,Ce酸化物/SiC触媒」と記載する)を得た。
実施例1で得た触媒の剥離性評価を行うため、試料を蒸留水に浸し、超音波洗浄機(アズワン株式会社製 USK-1R)を用いて、水中で10秒間超音波処理した後、試料を乾燥させた。乾燥後、触媒の付着状態を目視にて観察した。
実施例1で得たCo,Ce酸化物/SiC触媒とCo,Ce酸化物/コージェライト触媒について性能評価を行った。
実施例1で得たCo,Ce酸化物/SiC触媒について、各種塩素系VOCの分解実験(触媒活性試験)を行った。
酸性ガス存在下での触媒の耐久性を試験するため、従来の白金担持アルミナ触媒、Co,Ce酸化物/コージェライト触媒、Co,Ce酸化物/SiC触媒の塩酸暴露雰囲気下での劣化状況を比較した。方法としては、40mL 濃塩酸を入れた瓶をデシケーター中に置き、塩酸暴露雰囲気を調整した。さらに、上記3種類の触媒をデシケーター内に置いて室温で2週間静置させた。
