Rahman, Gul Chae, Sang Youn Joo, Oh-shim 2024-01-19T22:04:47Z 2024-01-19T22:04:47Z 2021-09-03 2018-07-19 0360-3199 https://pubs.kist.re.kr/handle/201004/121143 The production of hydrogen, the future fuel, on stable, efficient, and robust electrocatalysts represents an attractive approach for the conversion and storage of carbon-free energy resources. In this study, earth-abundant nickel sulfide (NiS) electrocatalyst were grown on fluorine-doped tin oxide (FTO) substrate by a simple and cost-effective chemical bath deposition for hydrogen evolution reaction (HER). Energy dispersive X-ray analysis and Xray photoelectron spectra indicated the presence of highly pure NiS. The HER performance of the catalyst was examined in alkaline solution (1.0 M NaOH; pH = 13.5). Notably, NiS film prepared at 100 degrees C demonstrated superior HER activity with an overpotential of 290 mV to afford a current density of 10 mA/cm(2) and a Tafel slope of 143.4 mV/dec which are among the promising results obtained for sulfide-based HER electrocatalysts. The catalyst exhibited 100% faradaic efficiency and electrochemical stability which indicate its potential as noble-metal-free HER electrocatalyst. (C) 2018 Hydrogen Energy Publications LLC.
