Abstract
Hydrogen production from NaBH4 hydrolysis is very important for environment-friendly fuel cells. Here Ni/CNTs nanocomposites were prepared by microwave-assisted method and used as the catalyst for catalytic hydrolysis of NaBH4. XRD and SEM characterization showed that uniform Ni/CNTs nanocomposites can be obtained through microwave heating and solvent optimization. Ni/CNTs nanocomposites exhibit excellent catalytic activity in the hydrolysis of NaBH4, i.e., the average hydrogen generation rate at 25°C is 840ml.min-1.g-1 for the CNTs-supported Ni/CNTs, while the hydrogen generation rate of 86ml.min-1.g-1 for unsupported Ni catalyst. Compared with the unsupported Ni catalyst, Ni/CNTs nanocomposites presented higher catalytic activity for hydrolysis of aqueous NaBH4 solution.
