负载型 Ni－Co－P／CNFs 催化剂的制备及释氢性能
Hydrogen generation from the hydrolysis of sodium borohydride solution over the supported Ni-Co-P/CNFs catalysts
摘要
Abstract
The Ni-Co-P catalysts supported on carbon nanofibers ( CNFs) were prepared via electroless deposition; the mass fractions of nickel, cobalt and phosphorus in Ni-Co-P layer are13 .30%, 82.25% and 4.45%, respectively , as det ermined by ICP-AES.The effec ts of catalyst amoun t, sodium borohydride and sodium hydroxide concentrations and reaction tem perature on the rate of hydrogen generationi n theh ydro lysis of alkaline NaBH4 solutio n we re investigated.The results indicated that the rate of hydrogen generation is proportional to the used catalyst amount; a maximum hydrogen generation rate of 18.044 L/(g・ min) is achieved at 45 ℃b y hydrolysis of 2.5% NaBH4 solution cont aining 5% NaOH and 7.5 g/L Ni-Co-P/CNFs catalyst with a Ni-Co-P loadin g of 18.127%.Moreov er, a kinetic study shows that the activation energy for the hydr olysis of alkaline NaBH4 solution under those conditions is 51.57 kJ/mol.关键词
