Ni掺杂ZIF-65复合材料的制备及其电催化析氧性能

以ZIF-65作为前驱体,通过简单的化学沉淀法对其进行了镍的掺杂。X射线衍射仪和扫描电子显微镜表征结果显示成功合成了形貌均匀的Ni掺杂ZIF-65。我们检验了ZIF-65以及Ni掺杂ZIF-65在三电极体系中的电催化氧析出反应的活性。结果表明Ni的掺杂提高了ZIF-65的电催化活性,并优于传统贵金属催化剂二氧化钌的电催化性能。

Preparation of Ni-doped ZIF-65 Composite and Exploration on Electrocatalytic Activity for Oxygen Evolution

ZIF-65 was used as a precursor, and doped with nickel by a simple chemical precipitation method. The results of X-ray diffraction and scanning electron microscope showed that nickel-doped ZIF-65 with uniform morphology was synthesized successfully. Here, we examined the catalytic activity of the electrocatalytic oxygen evolution reaction (OER) of ZIF-65 and Ni-doped ZIF-65 in a three-electrode system. The results show that the doping of Ni improves the electrocatalytic activity of ZIF-65 and is superior to the electrocatalytic performance of the traditional precious metal catalyst ruthenium dioxide.
