Ceria (CeO2)-based materials have been recognized as an important component of the three-way catalysts (TWCs) because of their excellent oxygen storage capacity (OSC). Since the 1990s, many studies have been devoted to CeO2-ZrO2 solid solutions, to reduce the emission of toxic pollutants (CO, NOx, hydrocarbons, etc.) from automobile exhaust due to their enhanced OSC in automotive TWCs, oxidation-reduction behavior and improved thermal stability at elevated temperatures. Herein, we describe the preparation and characterization of Ce0.5Zr0.5-xAlxOy solid solutions via a facile solvothermal route.
