摘要
综述了丙烷选择氧化制丙烯酸的复合金属氧化物催化剂(CMO)研究进展,特别是主要金属元素的作用以及催化剂制备过程中金属原子比、混合方法、干燥方式、焙烧气氛和pH值等因素对CMO催化性能的影响,并指出了今后的研究方向。
The development of complex metal oxide catalysts (CMO) for the selective oxidation of propane to acrylic acid (AA) is reviewed in this article. Especially, the role-played by each metal element in the CMO (Mo_aV_bTe_cNb_dO_n and Mo_aV_bSb_cNb_dO_n), and the effects of metal ratio, mixing, drying, calcination atmosphere, and gas flow and pH value on the performance of the catalysts are discussed. In addition, the review prospects the direction of development in future.
