Demonstrates enhanced catalytic activity in ethylbenzene oxidative dehydrogenation, suggesting improved efficiency under low-oxygen conditions.
In the Pt–Fe–Zr/Al 2 O 3 catalyst, Zr species promote electron transfer from Fe species to Pt species, increasing the Fe 3+ content and decreasing the number of strong acid sites, thereby enhancing catalytic activity and reducing coke deposition.
