英文摘要Electrolysis of seawater gets an attention to produce hydrogen for renewable energy technology. It significantly reduces the use of fresh water instead of seawater. Develop-ment of low temperature fabrication of electrocatalyst can explore seawater splitting by avoiding chloride reduction during the hydrogen production. In the present work, we fabricated low temperature hydrothermal growth of Cu2S electrocatalyst on Ni foam at constant temperature of 80 degrees C at different growth times of 1-3 h. The prepared Cu2S electrocatalyst grown for 1 h exhibited low overpotentials of 76 and 118 mV at 10 mA/cm2 (289 and 358 mV overpotentials at 100 mA/cm2) in 1 M KOH deionized water and seawater, respectively for hydrogen evolution reaction (HER). The Tafel plot of Cu2S catalyst grown for 1 h showed lesser Tafel slope value of 128 mVdec-1 than that of other growth times 2 h (136 mVdec-1) and 3 h (142 mV dec-1) indicating elevated electrocatalytic behaviour of Cu2S grown for 1 h. Electrochemical impedance spectroscopy (EIS) showed charge transfer resistance of 12.8U, 19.6 U and 25.7U, for Cu2S grown for 1, 2 and 3 h, respectively, this lower charge transfer resistance indicated higher charge transfer properties. The Cu2S electro-catalyst grown for 1 h sustained retention of 80% after 12 h continuous stability test. Therefore, the cost-effective and low temperature fabrication of Cu2S electrocatalyst pro-ceeds for development of largescale seawater splitting for hydrogen production.
