Synergetic engineering of ZnS/In2Te3 heterostructure for efficient oxygen evolution reaction

The potential of electrochemical water splitting to tackle energy and environmental issues has garnered substantial interest. In the present work, an effective ZnS/In₂Te₃ has been constructed by hydrothermal support on a stainless-steel strip and explored for oxygen evolution. The addition of ZnS modifies the band structure of In₂Te₃ and enhances its specific conductivity and capacitance on an intrinsic level, making rapid ion transportation. The optimized ZnS/In₂Te₃ displayed efficient oxygen evolution reaction (OER) performance with an overpotential of 228 mV and a Tafel slope of 111 mV dec⁻¹ with cyclic activity up to 1000 cycles in 1 M KOH solution. ZnS/In₂Te₃ has a large surface area (28 m³g⁻¹) and a charge capacitance of (.037 mF), according to studies using Brunauer–Emmett–Teller and double-layer capacitance. Combining several strategies improves overall electrochemical performance of ZnS/In₂Te₃, making it a promising option for use in state-of-the-art OER.
