Abstract

Hydrogen is not only an energy carrier but it’s also one of the substituting source that can be replace fossil fuels. Therefore possible adsorbent extensively being tested for better hydrogen adsorption. Recently, there are researches on hydrogen storage by using developed materials such as complex hydride, carbon nanotubes, zeolites and alloy metal. Geopolymer is proposed as a potential adsorbent due to economically and environmental friendly properties and lower cost compared to other developed materials and also derived from industrial waste. Thus, the scope of the hydrogen storage is wide, the author has narrowed down his study on hydrogen adsorption by using synthesized metakaolin alkali based geopolymer. Different molarity of alkali activator of sodium hydroxide (NaOH) of 8M, 10M and 12M were used to synthesis raw material of metakaolin in order to find which one is the best parameter for hydrogen adsorption uptake. Result shown that hydrogen adsorption on least molarity of alkali activator (8M), it adsorbs about 1.34 weight percentage though slightly lower than alkali activator of 12M which has about 1.49 weight percent. In nutshell, as molarity of the alkali activator (NaOH) increases, the hydrogen adsorption (wt%) also increases.
