Active three-way catalysis of rhodium particles with a low oxidation state maintained under an oxidative atmosphere on a La-containing ZrO2 support.

چکیده
Rhodium on a La-containing ZrO2 support effectively eliminated NOx from a synthetic auto exhaust gas under fluctuating oxygen conditions. Rhodium particles maintained a low oxidation state on the ZrO2-La2O3 mixed oxide even after treatment with 5% O2 at 773 K, highlighting the significant effect of the La addition.

متن کاملInfluence of electroplating parameters on microstructure and amount of ceramic particle deposition in Ni-Co-CeO2-ZrO2 composite coating
Austenitic stainless steels are high performance steels that have various applications in solid oxide fuel cells and boiler tubes under high temperature operating conditions. The Cr2O3 oxide layer formed on the steel surface becomes unstable at high temperatures and reduces the oxidation resistance of the steel. Therefore, protection of these steels at high temperatures is essential. Therefore,...
