Ni7S6/NiCo2S4纳米花的制备及其电催化析氧性能研究
Preparation of Ni7S6/NiCo2S4 Nanoflowers and Their Electrocatalytic Oxygen Evolution Performance
摘要
Abstract
With the progress of science and technology,the demand for sustainable energy is increasing,and hydrogen energy has been widely concerned by researchers because of its green environment.Hydrogen energy generated by electrochemical water splitting is a kind of green hydrogen production method.The sluggish kinetics of anodic oxygen evolution reaction(OER)results in higher energy consumption,limiting the wide application of electrochemical water splitting.At present,precious metals are generally considered to be the most advanced catalysts for electrochemical water splitting,but their scarcity and high cost seriously hinder their application.In this paper,Ni7S6 and NiCo2S4 grown in situ on NF by hydrothermal method,Ni7S6/NiCo2S4/NF-xh(x=6,8,10)electrodes were prepared.The effect of reaction time was studied for the composition,morphology,and properties of electrode materials.The experimental results show that Ni7S6/NiCo2S4/NF-8h electrode has excellent OER performance,the overpotential is 336 mV at 100 mA/cm2,the Tafel slope is only 62.8 mV/dec,and it has good stability.This study provides a new idea for the rational design and development of electrocatalytic oxygen evolution electrode materials.关键词
