Abstract ：
The oxidative dehydrogenation of propane (ODHP) represents a highly promising route for the industrial-scale production of propene. Non-metallic boron nitride (BN)-based materials, known for their high propene selectivity, have emerged as next-generation ODH catalysts. However, the real active sites on surfaces remain unclear due to the absence of visual experimental evidence. In this work, we introduce a chemical titration approach to clarify the active centers of NaOH modified BN (BN-NaOH) catalysts for ODHP. The BN-NaOH catalyst demonstrates outstanding performance, achieving over 90 % olefin selectivity and a stable propane conversion of 23.2 %. Notably, the turnover frequency (TOF) for B-OH sites reaching 1.2 h- 1, which significantly surpassed that of unmodified BN catalysts (0.6 h- 1). In situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) analysis revealed that the formation of OH-nests on the BN-NaOH surface was primarily accountable for the enhanced reactivity. Moreover, the crucial role of these OH-nests during ODHP was further validated through selective chemical titration of B-OH groups using benzoic anhydride.

Abstract ：
为进一步增加农村学生进入重点高校的机会，2014年国家实施针对农村地区倾斜招生的“高校专项计划”。“高校专项计划”取得了显著的成果，有效践行了教育公平理论。然而，“高校专项计划”在选拔标准、名额分配、专业与就业、政策执行等方面仍存在挑战。为深化教育公平，在实施“高校专项计划”过程中高校需要通过增强宣传、优化名额配置、严格政策执行与监管、加强后续扶持等手段，完善选拔机制，以推动教育资源更均衡分配，确保政策有效执行，从而推动“高校专项计划”改革和健康发展。
