Innovative Nanotechnology Techniques for Exploring Surface Area, Microstructure, Morphology, And Chemical Composition

Abstract

Nanomaterials possess a significantly larger surface area compared to the same mass of material produced in bulk. As a result, there is an increased proportion of surface atoms within the nanomaterial's structure. The greater the number of surface atoms, the more pronounced the surface-related effects become. The surface area and pore size of nanomaterials can be accurately measured using the BET method. To analyze the microstructure and morphology of samples with particles at the nanometer scale, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are commonly employed. TEM is widely regarded as the most effective method when detailed information about morphology and microstructure is required. Additionally, energy-dispersive X-ray spectroscopy (EDX) can be attached to both SEM and TEM for chemical composition analysis.
