摘要:
制备一系列介孔石墨相氮化碳负载氧化钒催化剂(V/CND)。通过N2吸-脱附、小角X 射线散射、透射电镜、X射线衍射、拉曼光谱、傅里叶红外光谱、X射线光电子能谱等表征手段对V/CND材料的结构、形貌等理化性质进行表征。在苯甲醇选择氧化反应中,V/CND催化剂表现出较高的催化活性及良好的循环使用性。与传统载体材料(SBA-15、碳纳米管和活性炭)相比,V/CND催化剂具有更高的选择性(>84%)。测试结果表明催化剂活性中心是分散的氧化钒物种。CND材料作为一种碱性载体可以有效地抑制苯甲醛的深度氧化。
Abstract:
Mesoporous graphitic carbon nitride(CND)was prepared and used as a catalytic support to load vanadia. The obtained V/CND materials were characterized by several characterization techniques including N2 adsorption-desorption, SAXS, TEM, XPS, Raman, FT-IR, and XPS spectroscopy. In the selective oxidation reactions of benzyl alcohol, the V/CND showed high catalytic performances and good recyclability, especially superior selectivities(> 84%)to the values obtained over other vanadia catalysts supported on traditional materials(SBA-15, carbon nanotubes, and active carbon). As revealed by FT-IR and XPS results, the active sites were attributed to the dispersed vanadia species. More importantly, the basic chemical environment of the CND support was regarded to effectively restrain the deep oxidation of benzaldehyde.
