Microhydrogen production with water splitting from daily ...
· HCl and KOH have been used for different types of alkaline solutions for the hydrogen generation from waste aluminum of 20, 40, and 100 meshes, and their Liincluded forms yielded interesting results. The optimum hydrogen rate was achieved using aluminum with a grain size of 100 mesh, followed by aluminum with a grain size of 20 and 40 meshes.
