Self-evolved BO_x anchored on Mg₂B₂O₅ crystallites for high-performance oxidative dehydrogenation of propane.

ABSTRACT: Oxidative dehydrogenation of propane (ODHP) is a promising process for producing propene. Recently, some boron-based catalysts have exhibited excellent olefin selectivity in ODHP. However, their complex synthetic routes and poor stability under high-temperature reaction conditions have hindered their practical application. Herein, we report a self-evolution method rather than conventional assembly approaches to acquire structures with excellent stability under a high propane conversion, from a single precursor-MgB₂. The catalyst feasibly prepared and optimized exhibited a striking performance: 60% propane conversion with a 43.2% olefin yield at 535°C. The BO_x corona pinned by the strong interaction with the borate enabled zero loss of the high conversion (aroun
