Synergistic modulation of electronic and acid–base properties of loaded Pt–Fe–Zr oxide catalyst for ethylbenzene oxidative dehydrogenation under low-oxygen conditions

Key Points

• The research aims to investigate the effects of Zr species on the electronic and acid-base properties of the Pt–Fe–Zr catalyst for ethylbenzene oxidative dehydrogenation.
• Analysis of Pt–Fe–Zr/Al2O3 catalyst composition and properties
• Measurement of electron transfer dynamics between Fe and Pt
• Assessment of catalytic performance under low-oxygen conditions
• Increased Fe3+ content observed with Zr species addition
• Reduction in the number of strong acid sites leading to lower coke deposition
• Enhanced overall catalytic activity noted under specified conditions
