ABSTRACT

The field emission scanning electron microscopy (FESEM) technique has been used to observe the surface morphology of activated carbon particles. These particles have a rough and porous surface, attributed to the presence of micro-pores, mesopores, and macropores. FESEM images have revealed that the pores are well distributed throughout the particles, and their sizes can range from 0.2 to 1 micrometer. The particles also have unique surface features and textures that are dependent on the processing method used to activate them. The FESEM observations have provided insight into the morphology, microstructure, pore structure, and surface texture of activated carbon particles, which have significant applications in environmental engineering. The surface morphology and pore structure revealed by FESEM imaging have shown that these particles are highly effective at adsorbing a wide range of pollutants due to their large surface area.Activated carbon has gained wide popularity due to its remarkable properties in various applications including gas scrubbing, water purification, catalysis, electrode material, and energy storage. The tremendous surface area, porosity, and chemical stability of activated carbon have made it an excellent material for numerous applications. Among the various types of activated carbon, coconut shell-based activated carbon has been widely recognized due to its sustainable and renewable source of raw material. This review will explain into the FESEM view of coconut-based activated carbon.
