Enhanced activity of CO2 methanation over Ni/CeO2-ZrO2 catalysts: Influence of preparation methods
详细信息    查看全文
文摘
Ni/CZ-AE prepared via ammonia evaporation method gave the best catalytic activity. Better activity is due to enhanced metal-support interaction. Methane formation does not go through CO formation route. CO2 is hydrogenated into formates on the support. Formation of methane was observed from 150 to 350 °C on Ni/CZ-AE catalyst.
