Impact of Hydrothermally Prepared Support on the Catalytic Properties of CuCe Oxide for Preferential CO Oxidation Reaction

CuCe mixed oxide is one of the most studied catalytic systems for preferential CO oxidation (CO-PrOx) purification hydrogen-rich gas stream. In this study, a series ceria supports were prepared via citrates-hydrothermal route by altering synthesis parameters (concentration and temperature). The resulting used preparation mixed-oxide catalysts wet impregnation. Various physicochemical techniques utilized characterization materials, whereas assessed in CO-PrOx reaction. Through proper modification hydrothermal parameters, CeO2 with tunable properties can be formed, thus targeting formation highly active selective catalysts. nature reduced copper species optimum content oxygen vacancies seems to key factors behind remarkable performance
