研究了在添加SiO2后得到的具有大表面积的Zr 1 − xCexO 2固溶体上用臭氧催化氧化甲苯的性能。在不同的复合氧化物中，Zr0.77Ce0.23O2-SiO2的甲苯转化率和CO2选择性最好。此外，它还具有上级保持臭氧诱导的活性氧物种的能力。焙烧温度的升高降低了催化剂的性能。
Catalytic oxidation of toluene with ozone over Zr1 −xCexO2solid solutions having a large surface area resulting from SiO2addition was evaluated. Among the different mixed oxides, Zr0.77Ce0.23O2–SiO2provided the best results for toluene conversion and CO2selectivity. In addition, it had superior capability to retain the active oxygen species induced by ozone. The rise in calcination temperature degraded the performance of the catalyst.
