Fe-CMK-3 nanostructured material applied in hydrogen uptake J.

Abstract

All over the world in the past decades, one of the most concerning subjects has been fossil fuel reduction, along with the global warming issue. These concerns have made hydrogen an ideal alternative to conventional fossil-fuel resources. Nevertheless, it has serious disadvantages, such as low volumetric and gravimetric densities that limit its storage [1]. 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 [2]. 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.
