Abstract:

Metal oxides catalysts have been widely used in a large variety of industrial processes, including ammonia synthesis, energy conversion and fine chemical synthesize. The morphology of metal oxides has an important effect on the catalytic performance. Compared to bulk materials, metal oxides catalysts with specific morphology exhibit unique structure properties in many aspects, which has become a research hotspot in the field of materials science. In this review, we highlight the preparation method, formation mechanism and structural property of metal oxides with various morphology, and their recent progresses in oxidation, steam reforming and hydrogenation are also reviewed. In the final section, future opportunities and challenges in the preparation of metal oxides catalysts are discussed, and some strategies to resolve these critical problems are further proposed.

Key words: various morphology, preparation method, formation mechanism, metal oxide catalysts
