| Abstract: | The main factors limiting water splitting producing hydrogen production are overpotential, activity and persistence of electrocatalysts. Herein, a novel NixCo1-x(OH)2 coupled with NiFe amorphous compound array growing on nickel foam substrate (expressed as NixCo1-x(OH)2/NiFe-AM) was developed by facile hydrothermal and electrodeposition methods. Significantly, NixCo1-x(OH)2/NiFe-AM with this unique structural exhibits superior activity and stability in the two half reactions of water electrolysis. In addition, when tested in an alkaline electrolyte with a current density of 10 mA cm?2, the overpotentials of HER and OER was 157 mV and 196 mV (60 mA cm?2), respectively. The stability can up to 60 h. These test results show through constructing hierarchical nano-thron architecture enhanced electrocatalytic activity to produce hydrogen and oxygen. |
