Operando capturing of surface self-reconstruction of Ni3S2/FeNi2S4 hybrid nanosheet array for overall water splitting

Hollow Mo-doped NiSx nanoarrays decorated with NiFe layered double-hydroxides for efficient and stable overall water splitting

“…S25d†) is obviously reduced, indicating that the S element is severely leached during the OER test, which has been reported in the literature. 61,62 Simultaneously, the attenuation of the Mo signal in the Mo 3d spectra may be attributed to the Mo 6+ species in the form of poly-molybdate, which would be dissolved in the alkaline solution during the continuous OER test (Fig. S25b†).…”

Atomic Heterointerface Engineering of Ni2P‐NiSe2 Nanosheets Coupled ZnP‐Based Arrays for High‐Efficiency Solar‐Assisted Water Splitting

“…Such results are assumed by the unique architecture of the ZnP@Ni 2 P‐NiSe 2 material with highly open channels that can effectively avoid the massive accumulation of bubbles and quickly discharge them from the active surface of the catalyst. By comparing with the recently reported bifunctional catalysts, the ZnP@Ni 2 P‐NiSe 2(+,‐) is one of the best devices for alkaline water splitting (Figure 4i), [ 38,52–74 ] demonstrating the noble metal‐free ZnP@Ni 2 P‐NiSe 2 heterostructured electrocatalyst is an effective and stable candidate for the overall water splitting to produce the green hydrogen.…”

Bell-shaped RuFe/Ni5P4 for efficient urea-assisted electrolytic hydrogen production

“…Therefore, the remarkable intrinsic property of the bell-shaped RuFe/Ni 5 P 4 catalyst ensures the fast surface kinetics via accelerated electron and mass transfer, signicantly promoting UOR performance with industrial-level current density. [41][42][43][44][45] In order to eliminate the inuence of ECSA, we normalized LSV and ECSA to intuitively compare the catalytic performance of the various materials. It can be further seen from the results that the addition of Ru plays a key role in improving the performance of the UOR (Fig.…”
