We prepared single Ni atoms embedded in an N-doped carbon catalyst with the assistance of metal organic frameworks. The dispersion of Ni atoms was verified by taking X-ray absorption fine structure measurements. Under the typical conditions for hydrogenation of acetylene, this single-site heterogeneous catalyst showed great potential as an alternative to Pd-based materials.
我们借助金属有机框架制备了嵌入氮掺杂碳催化剂中的单镍原子。通过进行X射线吸收精细结构测量验证了镍原子的分散情况。在乙炔加氢的典型条件下，这种单中心多相催化剂作为钯基材料的替代品显示出巨大潜力。
