Synthesis of Longtime Water/Air-Stable Ni Nanoparticles and Their High Catalytic Activity for Hydrolysis of Ammonia−Borane for Hydrogen Generation

摘要: In this paper, two kinds of Ni nanoparticles have been successfully synthesized without and with starch as the “green” protective material investigated catalysts for generating hydrogen from ammonia borane (NH3BH3, AB). Experimental investigations demonstrated that both possess high catalytic activities H2 generation aqueous solution AB. However, decrease seriously in course lifetime tests. contrast, almost keep unchanged even after 240 h. Moreover, XPS results show surface is still metallic h, while pure water nickel oxide. This means can oxidation air. The present efficient, low-cost, longtime water/air stable catalyst represents a promising step towar...
