Non-metallic heteroatom‐doped carbon materials are promising catalysts for the oxidative dehydrogenation of propane (ODHP), but their controllable synthesis remains challenging. Herein, a novel three-dimensional N, P co-doped carbon nanosheets (NPC-NS-T) catalyst is prepared, which shows an impressively catalytic performance in the ODHP reaction with high propane conversion (20.0%), propene (62.1%) and olefins (64.5%) selectivity at 500 °C, as well as the pretty good long-time stability. Comprehensive experimental characterizations reveal that the incorporation of appropriate P can not only helps to form more C=O species on the surface of NPC-NS-T, but also inhibits the consumption of C=O species under ODHP conditions, thereby remarkably improving the catalytic performance. This work paves the way for developing efficient biomass-derived carbon catalysts for the oxidative dehydrogenation reactions of propane.

生物分子衍生的三维 N、P 共掺杂碳纳米片用于丙烷的高效氧化脱氢


非金属杂原子掺杂碳材料是丙烷氧化脱氢 （ODHP） 的有前途的催化剂，但其可控合成仍然具有挑战性。在此，制备了一种新型三维 N，P 共掺杂碳纳米片 （NPC-NS-T） 催化剂，它在 ODHP 反应中表现出令人印象深刻的催化性能，在 500 °C 下具有高丙烷转化率 （20.0%）、丙烯 （62.1%） 和烯烃 （64.5%） 选择性，以及相当好的长期稳定性。综合实验表征表明，适当 P 的掺入不仅有助于在 NPC-NS-T 表面形成更多的 C=O 物种，而且在 ODHP 条件下抑制了 C=O 物种的消耗，从而显着提高了催化性能。这项工作为开发用于丙烷氧化脱氢反应的高效生物质衍生碳催化剂铺平了道路。
