文摘
- •
Development of highly efficient multicomponent Au/Ce1-xCuxO2/Al2O3 catalysts for the WGS reaction.
- •
Understanding the role of Au, Cu, CeO2 and their interactions to achieve good catalytic activity.
- •
Ce-Cu synergy and Au-support interaction as key features controlling catalyst's reducibility, oxygen vacancies population and oxygen storage capacity.
- •
The multicomponent catalysts present enough long term stability and tolerance towards start-up/shut-downs situations.
