A robust octahedral NiCoOxSy core-shell structure decorated with NiWO4 nanoparticles for enhanced electrocatalytic hydrogen evolution reaction

Monodispersed PtCo alloy nanoparticles with a modulated d-band center exhibiting highly efficient hydrogen evolution

“…The ECSA is linear with C dl and can be illustrated as follows: ECSA = S × C dl / C s , where S (0.07065 cm 2 ) is the glassy carbon electrode's surface area ( d = 3 mm) and C s is 0.040 mF cm −2 . 51 As shown in Fig. 3c, the C dl value of PtCo-NC (36.9 mF cm −2 ) is 4.92 times higher than that of Pt-NC (7.50 mF cm −2 ) and 4.14 times higher than that of Pt/C (8.92 mF cm −2 ).…”

Co(OH)2 nanosheets decorated with La-CoP nanorod array for alkaline electrocatalytic hydrogen evolution reaction

“…The larger the calculated C dl value, the larger the electrochemically active surface area (ECSA), which is beneficial as it exposes the active sites and increases the effective active sites. 47…”

“…The larger the calculated C dl value, the larger the electrochemically active surface area (ECSA), which is beneficial as it exposes the active sites and increases the effective active sites. 47 To further evaluate the reaction kinetics, electrochemical impedance spectroscopy (EIS) measurements were performed 6f shows the LSV curves of La-CoP/Co(OH) 2 /NF before and after the stability test. It can be seen that there was no significant attenuation of the curve, indicating that the catalyst had long-term durability.…”

Synthesis of NiMoO4/NiMo@NiS Nanorods for Efficient Hydrogen Evolution Reactions in Electrocatalysts

“…TMS materials have good prospects for large-scale production owing to their simple preparation process and low cost of raw materials [ 35 , 36 ]. Moreover, their abundant resources, environmental friendliness, and sustainability characteristics meet current requirements for environmental sustainability; thus, they offer significant potential in the field of electrochemical hydrogen production [ 37 ]. Franceschini et al [ 38 ].…”
