Porous materials for NH3-SCR of NOx reaction: synthesis, properties, and applications

Abstract

Selective catalytic reduction (SCR) is a widely used method for reducing nitrogen oxide (NOx) emissions from combustion processes. Porous materials, such as zeolites and metal–organic frameworks (MOFs), have gained significant attention as potential catalyst supports for NH3-SCR owing to their unique structural and chemical properties. This chapter provides an overview of porous-based materials and their applications in the NH3-SCR of NOx reaction. We begin with an introduction to the NH3-SCR of the NOx reaction and the types of porous materials including zeolites, metal–organic frameworks, and other mesoporous materials. The synthesis methods, properties, and performance of these materials are also discussed in detail. The application of porous materials in the NH3-SCR of the NOx reaction and the mechanistic overview of the SCR reaction are particularly highlighted. Overall, this chapter provides valuable insights into the use of porous materials for NH3-SCR of NOx reaction and their potential for future applications.
