Enhanced catalytic activity of electrodeposited Ni-Cu-P toward oxygen evolution reaction

Nitrogen‐doped Binary Spinel CuCo2O4/C Nanocomposite: An Efficient Electrocatalyst for Oxygen Evolution Reaction

“…In addition, the OER activity of N−CuCo 2 O 4 @N−C‐2 is also superior to N−CuCo 2 O 4 @N−C‐4. The observed OER activity of N−CuCo 2 O 4 @N−C‐2 outperforms many other OER catalysts, such as NiMoO 4 ( η =340 mV at 10 mA cm −2 ), [39] Ni 59 Cu 19 P 9 (η =307 mV at 10 mA cm −2 ), [40] CuO@ZnCo LDH/CF ( η =270 mV at 10 mA cm −2 ), [41] and S‐CoO/Co 3 O 4 ( η =275 mV at 10 mA cm −2 ) [42] . Figure 3b shows the Tafel slopes of N−CuCo 2 O 4 @N−C‐2 and the control samples.…”

Facile synthesis of nickel–copper hollow spheres as efficient bifunctional electrocatalysts for overall water splitting

“…29,41,57,58 However, the HER activity will decrease if the Ni/Cu ratio is further increased to 4/3, because Cu is less active than Ni in the water splitting system, and excessive Cu on the surface would prevent active sites with high activity from being exposed, resulting in less competitive performance. 24,59 To eliminate the contribution of the size, shape or morphology to electrocatalytic activity, the polarization curves have been normalized by ECSA (Fig. S5 and S6, ESI †).…”

Low‐Dimensional Metallic Nanomaterials for Advanced Electrocatalysis

“…Finally, the formed M–OOH* reacted with OH − to yield O 2 . [ 127–132 ] Similar to the reaction mechanism in alkaline media, the acidic OER also involved the formation of M–OH*, M–O*, and M–OOH* intermediates. The major difference between the intermediate reaction steps of the acidic OER and alkaline OER is the interaction of intermediates with OH − or H 2 O.…”
