Porous materials are vital in catalysis, gas storage, filtration, and energy applications due to their high surface area and tunable structure. Understanding their chemistry and design principles is key to developing next-generation functional materials. Introduction to Porous Materials presents the structural, physical, and chemical properties of porous solids, including zeolites, metal-organic frameworks (MOFs), and mesoporous silicas. The book discusses synthesis methods, characterization techniques, and industrial applications. It also highlights recent advances in nanostructured and hybrid materials. By bridging materials science and chemistry, it offers a clear and comprehensive guide to one of the most dynamic fields in modern materials research.
