英文摘要	The catalytic activity of ethanol reforming strongly depends on the interaction between Ir particles and ceria support, which is determined largely by the size of ceria particle. The catalyst with ceria size of 6-8 nm exhibited the strong metal-support interaction and resulted in the quite promising activity and stability. When ceria size was larger than 20 nm, large amounts of coke was formed on the catalysts due to the insufficient redox of CeO2. It seems that ceria particle in the range of 6-10 nm provides a sufficient Ir-CeO2 interfacial perimeter, which favors facile activation of water and/or oxygen and easy transfer of oxygen species to Ir particles, promoting carbon removal.
