Ruthenium-modified porous NiCo2O4 nanosheets boost overall water splitting in alkaline solution
文献摘要：
Exploring efficient oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)electrocata-lysts is crucial for developing water splitting devices.The composition and structure of catalysts are of great importance for catalytic performance.In this work,a heterogeneous Ru modified strategy is engi-neered to improve the catalytic performance of porous NiCo2O4 nanosheets(NSs).Profiting from favor-able elements composition and optimized structure property of decreased charge transfer barrier,more accessible active sites and increased oxygen vacancy concentration,the Ru-NiCo2O4 NSs exhibits excellent OER activity with a low overpotential of 230 mV to reach the current density of 10 mA/cm2 and decent durability.Furthermore,Ru-NiCo2O4 NSs show superior HER activity than the pristine NiCo2O4 NSs,as well.When assembling Ru-NiCo2O4 NSs couple as an alkaline water electrolyzer,a cell voltage of 1.60 V can deliver the current density of 10 mA/cm2.This work provides feasible guidance for improving the catalytic performance of spinel-based oxides.
