Fundamentals of Hierarchically Porous Materials and Its Catalytic Applications

The evolution of hierarchical porous materials has enhanced the productivity of the energy storage system owing to their higher surface area, space availability, low density, interconnected porosity at diverse scales, variable chemical composition, and excellent accommodation capability with thermal variation and space volume. The hierarchical porous structure benefits ion and electron transport, and diffusion, and mass transfer. With the varying pore structures, the electrochemical properties of hierarchical porous material vary. With the exact knowledge on the dependency of the pore dimensions and structures, the highly effective hierarchical porous structured materials could be fabricated with enriched catalytic performance. In this chapter, we have deliberated the characteristic properties of the hierarchically structured pores to summarize their recent development which mainly emphasized their catalytic applications. The first section of this chapter included brief discussions on the fundamentals, classification, and synthesis of the hierarchical porous materials. In the next section of this chapter, we mainly emphasized on application of hierarchical porous based on their catalytic activity. In the final section, the conclusion and the future aspects of hierarchical porous materials are included.
