One kind of OMC involves the carbon mesostructured from Korea (CMK). CMK-3 was chosen as a support material for hydrogen storage due to its large surface area, high chemical stability, uniform pore diameter, accessible porosity and three-dimensional conducting network.Metal particles dispersed in the porosity of active carbons are largely contributing to enhanced storage abilities. In this work we studied the influence of the incorporation of iron nanoparticles inside the channels of CMK-3. This could help and make it possible storing hydrogen in carbon and silica matrix but with another mechanism, with a better reversibility improving hydrogen adsorption/desorption behavior.An important conclusion of this work, concerns the design of iron oxide-decorated ordered mesoporous carbon CMK-3. The materials synthesized are promising in hydrogen uptake by weak link forces (physisorption). The activity of samples is ascribed to the improved dispersion of uniform vanadium nanoparticles as well as to the properly use of the support, which may probably originate a high surface area and pore volume, allowing large dispersion of iron.
