The formation of ZnCl2 activated carbon from a lignocellulosic material such as agave bagasse fibers has been characterized in situ, by environmental scanning electron microscopy. The carbonization process of raw bagasse fibers showed the development of a macroporous structure, which was related to the fibers chemical composition. In contrast, when fibers were activated with ZnCl2, a molten phase and a rapid evolution of gasses were observed. These results, which are recorded in a video, significantly contribute to the understanding of the chemical activation process of lignocellulosic materials to form activated carbon.
