Environmental pollution has attracted more and more attention and especially, the exhaust from vehicle has posed significant abatement problems. In response to the challenges associated with treatment of these exhaust, three-way catalysts (TWCs) have been widely used to reduce pollutant emissions from gasoline engine powered vehicles. CexZr1-xO2 solid solutions are the key components in TWCs. Through the transition between Ce3+ and Ce4+, the oxygen storage material buffers the lean-rich swings to achieve a ...
