Abstract
- The search for efficient non-precious metal or earth-abundant electrocatalysts is the key to drive clean energy technologies to develop a hydrogen economy. Here, we have developed a simple and scalable strategy for the synthesis of bimetallic ZnCo<subscript>2</subscript>(OH)F rod-like nanoarrays supported on nickel foam. The electrochemical test results show that ZnCo<subscript>2</subscript>(OH)F/NF exhibited a good electrocatalytic performance in the hydrogen evolution reaction (HER) at 10 mA cm<superscript>−2</superscript>, with an overpotential of 121 mV, a significant Tafel slope value of 129.9 mV dec<superscript>−1</superscript> and excellent stability at different current densities. Due to bimetallic hybridization, this material has excellent catalytic activity and good H* absorption free energy active sites, which indicate its operability in rational hydrogen production applications. This work provides a superior synthetic strategy for the effective design and rational fabrication of low-cost, highly active, and highly stable non-precious metal HER electrocatalysts for electricity-to-hydrogen applications.
