Kinetic Study of Hydrogen Generation Reaction Over Co/Salep Nano Catalyst

Salep-stabilized Cobalt nano catalyst has been synthesized with chemical reduction method using chloride salt of cobalt for hydrogen generation from hydrolysis of sodium borohydride (NaBH4) under reflux condition. Kinetic studies on the hydrolysis reaction of NaBH4 are investigated through three factors: (1) effect of NaBH4 concentration, (2) effect of the catalyst dosage and (3) effect of solution temperatures. The activation energy (Ea) was achievement indicated that the compound of Co/Salep has the lowest agglomeration and the highest rate of hydrogen generation (Ea₌28.7 kJmol-1).
