Abstract
Abstract In recent years, hexagonal boron nitride (hBN) has emerged as an unexpected catalyst for the oxidative dehydrogenation of alkanes. Here, the versatility of hBN was extended đồ sộ alkane oxidative cracking chemistry by investigating the production of ethylene and propylene from n ‐butane. Cracking selectivity was primarily controlled by the ratio of n ‐butane đồ sộ O 2 within the reactant feed. Under O 2 ‐lean conditions, increasing temperature led đồ sộ increased selectivity đồ sộ ethylene and propylene and decreased selectivity đồ sộ CO x . In addition đồ sộ surface‐mediated chemistry, homogeneous gas‐phase reactions likely contributed đồ sộ the observed product distribution, and a reaction mechanism was proposed based on these observations. The catalyst showed good stability under oxidative cracking conditions for 100 h time‐on‐stream while maintaining high selectivity đồ sộ ethylene and propylene.
