Abstract

In this paper, Fe-doped nickel selenide and nickel sulfide composites was in-situ grown on nickel foam (NF) to prepare Fe-NiSe@NiS/NF by solvothermal method. Benefit from the optimized electron structure by Fe doping, the synergistic effect of NiSe@NiS and faster electron transfer, Fe-NiSe@NiS/NF exhibited excellent OER activity with the overpotential of 330 mV at 150 mA/cm² in 1 mol/L KOH solution. The voltage barely changed after 40 h of test.

电子调制和协同效应对掺铁NiSe@NiS复合材料析氧性能的影响

本文在泡沫镍（NF）上原位生长了掺Fe的硒化镍和硫化镍复合材料，制备了Fe-NiSe@NiS/溶剂热法测定NF。得益于Fe掺杂优化的电子结构NiSe@NiS以及更快的电子转移，Fe-NiSe@NiS/NF在1mol/L KOH溶液中在150mA/cm2下具有330mV的过电位，表现出优异的OER活性。测试40小时后，电压几乎没有变化。

期刊介绍： Journal of Fuel Chemistry and Technology (Ranliao Huaxue Xuebao) is a Chinese Academy of Sciences(CAS) journal started in 1956, sponsored by the Chinese Chemical Society and the Institute of Coal Chemistry, Chinese Academy of Sciences(CAS). The journal is published bimonthly by Science Press in China and widely distributed in about 20 countries. Journal of Fuel Chemistry and Technology publishes reports of both basic and applied research in the chemistry and chemical engineering of many energy sources, including that involved in the nature, processing and utilization of coal, petroleum, oil shale, natural gas, biomass and synfuels, as well as related subjects of increasing interest such as C1 chemistry, pollutions control and new catalytic materials. Types of publications include original research articles, short communications, research notes and reviews. Both domestic and international contributors are welcome. Manuscripts written in Chinese or English will be accepted. Additional English titles, abstracts and key words should be included in Chinese manuscripts. All manuscripts are subject to critical review by the editorial committee, which is composed of about 10 foreign and 50 Chinese experts in fuel science. Journal of Fuel Chemistry and Technology has been a source of primary research work in fuel chemistry as a Chinese core scientific periodical.
