Phosphorus-doped activated carbon (P@AC), prepared by wet impregnation method, can serve as efficient metal-free catalyst for the dehydroaromatization of n-hexane to benzene under mild conditions. The effect of phosphorus amount and phosphorus sources including phenylphosphonic acid (PPOA), phosphorus acid (H₃PO₄), triphenylphosphine (TPP), and tributylphosphine (TBP) on catalytic performance of P@AC were investigated. Combining with characterization analysis, functional groups containing -P(O)(OH) on the carbon surface are believed to be the active sites for dehydroaromatization catalysis.

对于磷掺杂的活性炭催化剂Ñ己烷脱氢芳构化反应

磷掺杂的活性碳（P @ AC），通过湿浸渍法制备，可以作为有效的无金属催化剂的脱氢芳构化Ñ正己烷苯温和的条件下。研究了磷含量和磷源（包括苯膦酸（PPOA），磷酸（H ₃ PO ₄），三苯膦（TPP）和三丁基膦（TBP））对P @ AC催化性能的影响。结合表征分析，碳表面上包含-P（O）（OH）的官能团被认为是脱氢芳构化催化的活性位点。
