摘　　要：以Fe3O4微球为模板,PdCl2乙醇胶体溶液为活化剂,乙醇为化学镀溶剂,制备了磁性Fe3O4/Ni–B核壳催化剂。采用扫描电镜、能谱仪和X射线光电子能谱仪表征了Fe3O4/Ni–B的表面形貌、组成及各元素在镀层中的存在形式。以Fe3O4/Ni–B为催化剂,对NaOH和NaBH4的混合液进行水解产氢试验。研究了化学镀时所用镀液的体积以及混合液中NaOH和NaBH4的质量分数对Fe3O4/Ni–B催化产氢性能的影响。结果表明,以0.4mL化学镀液制备的Fe3O4/Ni–B为催化剂,混合液中NaOH和NaBH4的质量分数分别为10%和2%时,Fe3O4/Ni–B的催化产氢性能最好。A magnetic Fe304/Ni-B core-shell catalyst was prepared using Fe304 microsphere as templates, alcohol solution of PdC12 colloid as activator, and alcohol as medium of electroless plating. Scanning electron microscope, energy- dispersive spectroscopy and X ray photoelectron spectroscopy were used to characterize the surface morphology, composition, and existence form of each element in coating, respectively. Hydrolysis experiment to produce hydrogen was carried out in a mixed solution consisting of NaOH and NaBH4, using the Fe3O4/Ni-B as catalyst. The effects of plating bath volume in electroless plating and mass fractions of NaOH and NaBH4 in mixed solution on the catalytic performance of Fe3O4/Ni-B for hydrogen production were studied. The results show that the Fe304/Ni-B catalyst obtained from 0.4 mL electroless plating bath has best performance for hydrogen production in a solution containing 10wt% NaOH and 2wt% NaBH4.
