Flower-like NiCo2S4/NiFeP/NF composite material as an effective electrocatalyst with high overall water splitting performance
文献摘要：
Rational design and building of high efficiency,secure and inexpensive electrocatalyst is a pressing de-mand and performance to promote sustainable improvement of hydrogen energy.The bifunctional elec-trocatalysts for oxygen evolution reaction(OER)and hydrogen evolution response(HER)with high cat-alytic performance and steadiness in the equal electrolyte are extra treasured and meaningful.Herein,a unique three-dimensional(3D)structure electrocatalyst for NiCo2S4 growing on the flower-like NiFeP was designed and synthesized in this study.The results show that the flower-like NiCo2S4/NiFeP/NF com-posite electrocatalyst has large specific surface area,appropriate electrical conductivity,and greater lively websites uncovered in the three-dimensional structure,and affords extraordinary electrocatalytic over-all performance for the ordinary water splitting.In alkaline solution,the OER and HER overpotentials of NiCo2S4/NiFeP/NF only need 293 mV and 205 mV overpotential to provide the current densities of 100 mA/cm2 and 50 mA/cm2,respectively.This high electrocatalytic activity exceeds the catalytic ac-tivity of most nickel-iron based electrocatalysts for OER and HER process.Accordingly,the optimized NiCo2S4/NiFeP/NF sample has higher stability(24 h)at 1.560 and 10 mA/cm2,which extensively speeds up the overall water splitting process.In view of the above performance,this work offers a fine approach for the further improvement of low fee and excessive effectivity electrocatalyst.
