In this work, we prepared activated carbon derived from rice husks (RHC) using chemical activation with KOH ratio. The results showed that significant increase in specific surface area and optimum pore size for hydrogen storage of RHC by KOH activation. Then, it was interesting note to that the best hydrogen storage capacity of 2.85wt.% was observed in the RHC1 sample (KOH ratio of 1). The hydrogen...
Ultra-microporous carbons were prepared from CF (cellulose fibers) by physical activation at various temperatures. Physical activation using steam was observed to have an influence on the development of new pores and the expansion of pore sizes and to be effective in developing optimal micropores for CO2 adsorption on the carbon surface. On optimizing the preparation conditions, the synthesized materials...
