The effect of the nature of the support and the method of preparation of indium–aluminum(zirconium) oxide compositions on their acid–base characteristics, which determine the catalytic activity in oxidative dehydrogenation of propane with participation of CO2, was established. The highest selectivity for propylene (51%) is achieved over the In2O3–Al2O3 catalyst, which is due to the presence on its surface of stronger Lewis acid sites for activation of C3H8 and to a higher concentration of base sites for activation of CO2.

In2O3-Al2O3 (ZrO2) 组合物的酸碱特性对其在丙烷与 CO2 氧化脱氢反应中催化性能的影响

确定了载体的性质和制备氧化铟铝（锆）组合物的方法对其酸碱特性的影响，这些特性决定了在 CO2 参与下丙烷氧化脱氢的催化活性。丙烯的最高选择性 (51%) 在 In2O3-Al2O3 催化剂上实现，这是由于其表面存在用于活化 C3H8 的更强的路易斯酸位点和用于活化 CO2 的更高浓度的碱位点。
