英文摘要 | Development of single-atomic-site catalysts with high metal loading is highly desirable but proved to be very challenging. although utilizing defects on supports to stabilize independent metal atoms has become a powerful method to fabricate single-atomic-site catalysts, little attention has been devoted to cation vacancy defects. here we report a nickel hydroxide nanoboard with abundant ni2+ vacancy defects serving as the practical support to achieve a single-atomic-site pt catalyst (pt-1/ni(oh)(x)) containing pt up to 2.3 wt% just by a simple wet impregnation method. the ni2+ vacancies are found to have strong stabilizing effect of single-atomic pt species, which is determined by x-ray absorption spectrometry analyses and density functional theory calculations. this pt-1/ni(oh)(x) catalyst shows a high catalytic efficiency in diboration of a variety of alkynes and alkenes, yielding an overall turnover frequency value upon reaction completion for phenylacetylene of similar to 3000 h(-1), which is much higher than other reported heterogeneous catalysts. |
