中文摘要:

      制备了掺杂不同含量钒和铁的FSM(Folded-sheet mesoporous materials)-16分子筛,采用X粉末衍射仪(Powder X-ray Diffractometer,XRD)、红外光谱仪(Infrared Spectrometer,IR)研究了V-FSM-16和Fe-FSM-16分子筛的结构特征和表面性质,并考查了掺杂不同量金属的FSM-16分子筛对苯氧化成苯酚催化性能的影响,探求掺杂合适金属及合适量的催化剂。实验结果表明掺杂金属钒与载体物质的量比为0.077时,催化剂的催化活性最高。

英文摘要:

      V,Fe-modified FSM-16 molecular sieves with different metal-doped quantities were successfully synthesized.The features and surface properties of V,Fe-modified FSM-16 molecular sieves were detailedly characterized by X-ray diffractometer(XRD) and infrared spectroscope(IR).The modified FSM-16 molecular sieves with different vanadium and iron quantities had different effect on the catalytic performance for the conversion from benzene to phenol.After researching different metal and appropriate doped quantities,...
