Nanoporous materials are a major research focus due to their unique structures and diverse applications in catalysis, drug delivery, and environmental remediation. This chapter reviews the synthesis, characterization, and practical applications of nanoporous materials. It examines various synthesis methods, detailing their principles, advantages, and limitations. Key characterization techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), and atomic force microscopy (AFM) are discussed for assessing important properties like surface area and pore size. The chapter also highlights the performance of nanoporous materials in enhancing reaction rates in catalysis, improving drug delivery systems, and aiding in pollutant degradation. Ideally, this chapter contributes to providing researchers and practitioners with the knowledge necessary to advance the further development and application of nanoporous materials in various technological and industrial areas.
