Metallic Nanomaterials as Catalysts

Md Jafar Sharif, M. Jakir Hossain

With the advancement of nanoscience and nanotechnology, metallic nanomaterials emerged as a bridge between homogeneous and heterogeneous catalysis due to their higher catalytic activity, selectivity, and easy separation while maintaining high stability. The novel catalytic properties of metallic nanomaterials originate from their unique geometric structures and electronic structures that are remarkably different from the corresponding bulk materials. Metallic nanomaterials have a high population of atoms with low coordination number and quantized energy levels which depends on the structural parameters such as the size and shape of the nanomaterials. For bimetallic nanomaterial, the composition is another key parameter to regulate the catalytic properties. In this chapter, factors affecting the catalytic properties of metallic nanomaterial are discussed in detail with several important applications.
