| 中文摘要 | ni-co-b catalyst-promoted hydrogen generation by hydrolyzing nabh4 solution for in situ hydrogen supply of portable fuel cells |
| 英文摘要 | a series of ni-co-b catalysts were synthesized by a two-step technique, namely, chemical reduction was used to prepare the precursors, and heat-treatment was used to adjust the crystal structures. the structures of the as-prepared ni-co-b catalysts were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), x-ray photoelectron spectroscopy (xps), and nitrogen adsorption-desorption test. the catalytic activities of the ni-co-b catalysts for nabh4 hydrolysis were evaluated in a successive hydrogen generation mode, where a 5% nabh4 + 1% naoh solution was pumped into the hydrogen generation reactor with a feeding rate of 5 ml per minute. it is found that the heat-treatment affects the crystal structure, the apparent morphology, the oxidation state, the surface structure, as well as the hydrogen generation performances of the ni-co-b catalysts. the sample treated at 673 k achieves an average hydrogen generation rate of 708 ml min(-1) g(-1) (catalyst), which can give successive hydrogen supply for an 115 w portable proton-exchange membrane fuel cell (pemfc).
