چکیده انگلیسی
We demonstrate a facile preparation of fishbone-like Co-B nanoparticles via electroless plating method for the first time, as evidenced by XRD, SEM and AFM results. The catalytic activities of the obtained fishbone-like Co-B nanoparticles have been investigated for hydrogen generation from NaBH4 solution. The results reveal that the fishbone-like Co-B nanoparticles exhibit high catalytic activity during hydrolytic dehydrogenation of NaBH4. The hydrogen release rate and the activation energy are 10089.1Â mLÂ minâ1Â gâ1 and 34.2Â kJÂ molâ1, respectively. More importantly, the fishbone-like Co-B nanoparticles have retained about 84.0% catalytic activity of its first activity after 5 cycles, which illustrates that the Co-B catalysts composed of fishbone-like catalysts show much improved reusability contrast to those common Co-B catalysts reported in the literature.
