Multicomponent Bismuth Molybdate Catalyst: A Highly Functionalized Catalyst System for the Selective Oxidation of Olefin

Abstract

Publisher Summary This chapter focuses on the multicomponent bismuth molybdate catalyst which is a highly functionalized catalyst system for the selective oxidation of olefin. Some progress is made in explaining the splendid catalytic performance of multicomponent bismuth molybdates that are used widely for the industrial oxidations and ammoxidations of lower olefin. The catalytic activity and selectivity are enhanced by the multifunctionalization of the catalyst systems. Many functions newly introduced are deeply associated with lattice vacancies formed by the introductions of third and fourth elements. The design of the excellent oxidation catalyst depends seriously on the method of selecting these additives by considering their valencies, electronegativities, and ionic radii. The rapid migration of oxide ion and electron transfer are also important in enhancing the catalyst stability. Thus, the appropriate introduction of additional elements into the catalyst system makes it more flexible and durable under the working conditions.
