TEM observation of mesoporous activated carbons supporting metal oxide particles

摘要

Activated carbons were prepared from the mixture of coal and metal (Fe, Ni, Co) complex, and their selective mesoporous structures supporting metal-oxide particles were confirmed with N_2 adsorption isotherms and X-ray diffractionpatterns. Transmission electron microscope (TEM) observation clearly showed disordered carbon microtexture and homogeneous dispersion of nano-scale oxide particles in the carbon matrix. Formation of mesopores in the activated carbons was related with the behavior of oxide particles during the activation process.
