Abstract
The unexplored electronic coupling and insufficient contact of active constituents between electrodes are still a barrier to the current development of cost-effective, high-performance electrocatalysts of the oxygen evolution reaction (OER). The hybrids Ni/Co-ZIF67@MXene have been prepared in-situ here in an HF vapor-assisted delamination strategy, which allows comfortable interfacial coverage between bimetallic ZIF nanocrystals and conductive MXene nanosheets. The existence of a coherently coupled hybrid architecture and the creation of an expanded reservoir of active sites accessible is established by extensive physicochemical characterisations. Electrochemical evaluation indicates an overpotential of 270 mV at 10 mA.cm⁻¹ and a Tafel slope of 57.7 mV.dec⁻¹ and particular operational stability of 16 h. This is because the enhanced performance is explained by synergistic electronic interactions and enhanced charge transfer at the heterointerface. Although these are the benefits, research on the long-term durability and quantifying intrinsic activity is needed. This work highlights the importance of interfacial engineering in the design of advanced OER electrocatalysts.
