Abstract
Description
硝酸銀水溶液中にAgの量がYの原子数を基準にしてそれぞれ第1表に示す割合となるようにマンガン酸イットリウムYMnO3からなる担体粉末を投入し、30分間攪拌した。得られた各々のスラリーを直径25.4mm×長さ76.2mmのコージェライト製パティキュレートフィルター表面にコートさせた。これらを120℃で3時間乾燥した後、空気中500℃で1時間焼成した。得られた各々のパティキュレートフィルター形状の排ガス浄化用触媒構成体のYMnO3の担持量は40g/Lであり、Agの担持量は金属換算で第1表に示す通りであった。なお、実施例5で得た排気ガス浄化用触媒構成体の一部分の電子顕微鏡写真を図1に示す。図1の電子顕微鏡写真において1目盛の長さは6nmであり、10目盛りで60nmであることを示している。図1から明らかなように、YMnO3担体上に担持されているAg粒子の大きさは10〜20nm程度である。
実施例1〜5及び比較例1で得られた各々の排気ガス浄化用触媒構成体を大気中、700℃で30時間耐久処理した。耐久処理後の排気ガス浄化用触媒構成体の触媒活性を以下のようにして評価した。
実施例5で得られたAg/YMnO3担持排気ガス浄化用触媒構成体(Ag担持量2.3g/L)、比較例1で得られたYMnO3担持排気ガス浄化用触媒構成体(貴金属担持なし)、硝酸銀の代わりに硝酸パラジウムを用いた以外は実施例5と同様にして得られたPd/YMnO3担持排気ガス浄化用触媒構成体(Pd担持量0.4g/L)(比較例2)、及び硝酸銀の代わりにジニトロジアンミン白金を用い、YMnO3の代わりにAl2O3を用いた以外は実施例5と同様にして得られたPt/Al2O3担持排気ガス浄化用触媒構成体(Pt担持量0.5g/L)(比較例3)をそれぞれ大気中、700℃で30時間耐久処理した。耐久処理後の各々の排気ガス浄化用触媒構成体について下記の方法でスス燃焼速度を測定した。
