Sulfonated montmorillonite was prepared by using two steps, initially montmorillonite K10 (MMT) powder was reacted with hydrochloric acid for exchanging H+ ions with cations of montmorillonite and obtained H-montmorillonite (HMMT). Finally, HMMT is sulfonated by treating with chlorosulfonic acid to get an acidic heterogeneous sulfonated montmorillonite (SMMT) catalyst. The prepared catalysts were characterized by EDX, XRD, FT-IR, SEM, acidity-determination, and TGA. SMMT was applied to hydrogen generation from sodium borohydride hydrolysis reaction under different reaction parameters. The catalyst exhibited high catalytic activity in terms of H2 evolution rate and stability.
