| 摘 要： | 为进一步提高V2O5/TiO2催化剂对气相一步催化合成烟酸反应的活性和选择性.通过浸渍法制备一系列掺杂过渡金属铬的V2O5/TiO2催化剂,并对催化剂进行了BET、XRD、H2-TPR、NH3-TPD表征.结果表明,掺杂Cr后催化剂产生了新晶相CrVO4,减小了V2O5晶粒尺寸,并提高了催化剂的酸性,可较大地提高催化剂...

| Abstract: | In order to improve activity and selectivity of gas phase catalytic oxidation of 3-picoline to nicotinic acid on V2O5/TiO2,a series of V2O5/TiO2 catalysts doped with different Cr content were prepared by impregnation method,and characterized by XRD,BET,H2-TPR,NH3-TPD.The results showed that a new crystalline phase CrVO4 appeared on the Cr-doped catalysts,which reduced V2O5 and TiO2 grain size,and increased the acidity of catalysts.A small amount of Cr doping would promote the activity of the lattice oxygen ... |
