Carbon Capture Science & Technology, Journal Year: 2023, Volume and Issue: 10, P. 100173 - 100173

Published: Dec. 8, 2023

The interfacial structure of metal and oxide support plays a pivotal role in reverse water gas shift (RWGS). However, rare work investigated the factor metal-oxide interface during RWGS reaction. In this work, Cu/CeO2 catalysts was designed through thermal treatment copper nitrate salt on CeO2 with an H2 atmosphere under different temperatures, CO2 hydrogenation performance studied at 400°C to investigate effect Among these prepared catalysts, Cu/CeO2-400 achieved best conversion activity (CO production rate 1.23 mol/gcat.h). Cu interacted form Cu-O-Ce induced more oxygen vacancy formation. around Cu-CeO2 enhanced adsorption promoted conversion. reacted active hydrogen formate species (COOH), then COOH dissociated into CO OH adsorbed surface Cu-CeO2. These results gave insights design highly effective catalyst for hydrogenation.
