Abstract

Abstract:

Due to their unique acidity and redox performance, polyoxometalate materials have attracted wide attention in oxidative desulfurization. In this work, the research progress on oxidative desulfurization in fuel by polyoxometalate materials is reviewed, including the characteristics of polyoxometalate based ionic liquids and polyoxometalate catalysts supported on metal-organic frameworks, oxide and carbon materials, and their desulfurization performance for various sulfur compounds. The combination of polyoxometalate with ionic liquid or other materials can not only enhance the catalytic activity, but also improve the thermal stability and reusability of the catalyst. Furthermore, the characteristics and development prospects of various carriers were compared in detail. Finally, the development directions of polyoxometalate materials in oxidative desulfurization is prospected, such as the development of polyoxometalate materials with high catalytic activity, excellent recycling performance and good economic and applicability.
