Electrocatalytic application of graphitic carbon Nitride(gCN) in boosting the performance of copper nickle tin Sulphide(CNTS) hierarchical structure

The growing demand for energy, as well as the impact on the environment as a result of human activity, has prompted a renewed focus on the development of cleaner alternative fuels. Because of its pure combustion products, hydrogen gas is being used as an alternative in the development of sustainable energy sources. A simple hydrothermal technique was used to prepare copper nickel tin sulphide (CNTS) decorated graphitic carbon nitride (gCN). CNTS-gCN samples were further prepared on different concentrations of gCN that varies from CNTS-gCN(10 mg-50mg) and analyzed under various characterization for its structural, morphological, and electrochemical properties. Field Emission Scanning Electron Microscopy (FESEM), Raman and HR-TEM (High Resolution-Transmitting Electron Microscopy) techniques were used to examine the morphology and surface structure of CNTS-gCN. Owing to its exclusive electrocatalytic property as low charge transfer resistance and high electrochemically active surface area, the composite material reveals a superior catalytic stability for the production of hydrogen energy. The hierarchical flower like structures were still maintained even after the addition of g-CN at different loading concentrations (10-50) respectively. The objective of this research is to prepare a new electrocatalyst based on CNTS with an increased HER activity.& COPY; 2023 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
