摘要:
通过沉淀法制备层状镍钴氢氧化物前驱体,再利用等离子对前驱体进行处理,得到镍钴氧化物。采用X射线衍射分析、场发射扫描电子显微镜、透射电子显微镜和BET法对镍钴氧化物的物相、形貌结构及孔径分布进行研究,并通过循环伏安法、线扫描伏安法等电化学测试评估材料的析氧反应(OER)催化活性。与传统热处理方法相比,低温等离子体方法制备的镍钴氧化物具有更大的比表面积(77.13 m2/g)和更丰富的孔结构(平均孔径18.40 nm),并且在碱性电解质溶液中表现出更优的OER活性。这说明低温等离子体处理方法能够有效提升镍钴氧化物的OER性能。
Abstract:
The layered nickel cobalt hydroxide precursor was prepared by precipitation method,and then treated by plasma to obtain the nickel cobalt oxide. The X-ray diffraction,scanning electron microscopy,transmission electron microscopy and brunauer-emmett-teller method were used to characterize the phase,morphology and pore size distribution of nickel-cobalt oxide. The oxygen evolution reaction performance of the materials was investigated by cyclic voltammetry and linear sweep voltammetry. Compared with traditional heat treatment methods,the nickel cobalt oxide prepared by low-temperature plasma method not only has larger specific surface area(77.13 m2/g) and porous nanostructure(average pore size of 18.40 nm),but also exhibits better oxygen evolution reaction activity in the alkaline electrolyte,which indicates that low-temperature plasma treatment method can effectively improve the oxygen evolution reaction performance of nickel cobalt oxide.
