Direct solvent free synthesis of bare α-NiS, β-NiS and α-β-NiS composite as excellent electrocatalysts: Effect of self-capping on supercapacitance and overall water splitting activity

“…11b, indicating best result for NISE-3. For NiS/Ni 3 S 4 synthesized by Qin et al, the HER activity reached a low overpotential of 221 mV at 10 mA/cm 2 , which is comparable with our results 79 , whereas, it is much superior as compared to NiS (474 mV at 10 mA/cm 2 ), NiS 2 (454 mV at 10 mA/cm 2 ), Ni 3 S 2 phase (335 mV at 10 mA/cm 2 ) and Ni 3 S 2 -CNTs composites (480 mV at 10 mA/cm 2 ) 25,80 . A detailed comparison is given in Table S5, ESI.…”

Facile synthesis of Ni3S2/rGO nanosheets composite on nickel foam as efficient electrocatalyst for hydrogen evolution reaction in alkaline media

“…2,31,32 Particularly, Ni 3 S 2 nanomaterial has been considered as one of the promising candidates for HER due to its low cost, high abundance, and easy preparation processing. [33][34][35][36][37][38] Many studies showed that the electrocatalytic activities of three-dimensional (3D) Ni 3 S 2 supported on Ni foam were higher than those of the molybdenum dichalcogenides in basic media because of their intrinsically high catalytic activity toward HER. 35,36,39 Note that 3D structure can (i) facilitate the diffusion of electrolyte and hydrogen bubbles, (ii) ensure a large surface area associated with the nanostructured active materials along with the absence of binder, accelerating the surface reaction, and (iii) enable the direct contact of the nanostructured active materials to the underneath conductive substrate which ensures a possible high efficiency.…”

High Performance Non‐enzymatic Glucose Sensor Based on One‐Step Electrodeposited Nickel Sulfide

“…Electrochemical non-enzymatic glucose sensors have been reported using hydrothermally synthesized Ni 3 S 2 as an electrode material. [39,40] However,t his is the first report of non-enzymatic glucosed etection using as ingle-step electrodeposited NiS film without furthermodification. We describe the fabrication of the electro-deposited nano-NiS thin film sensor and describe sensing of glucoseu sing CV and amperometry techniques.…”
