“…This is in confirmation with the surface area calculated from the voltammetry technique, meaning that a higher surface area has provided higher oxidation rates for MOR. The chronoamperometry results outperform previous explorations on nickel-containing electrocatalysts for MOR. − ,− The steady-state current densities for MOR oxidation for nickel-based electrodes reported in the literature are summarized in Table .…”

In this report, a nickel nanoscaled morphology was synthesized by two-step cathodic electrodeposition on a microporous copper template. The resulting morphology, nanosheets formed on 3D micropores, offers incredible cyclic stability of almost 100% and facilitates transport mechanisms while significantly preserving the active surface area. The origin of the nanosheets is assumed to be the presence of a small amount of iron cations in the electrolyte bath during the final deposition step. By altering the deposition current density of this step, three samples were prepared and compared in terms of the resulting morphology, chemical composition, surface area, wettability, and activation toward the methanol oxidation Reaction. Results show that an increase in the deposition current density in the range of this study produces finer and denser nanosheets, a higher content of reduced iron, a larger surface area, and greater activity toward MOR. The current density for methanol oxidation was exceptional among all other studies on nickel-containing electrocatalysts, yielding a steady-state current density of 135 mA cm −2 at 600 mV versus SCE. All samples offered superhydrophilicity.

“…[53] In Figure 4d, the peaks of 161.5 eV and 162.6 eV can be identified as S À 1 , which is is a little lower compared with the 161.8 eV and 162.9 eV peaks in the literature. [54,55] This is because S has a strong electron affinity. After sulfurization, the the electrons on the Ni and Co elements are transferred to the S atoms, resulting in more Ni 3 + and Co 3 + , which improve the catalytic performance of methanol.…”

Nowadays, the development and utilization of clean energy are becoming increasingly urgent. Among them, methanol is a new, clean, and efficient energy source. Therefore, more and more studies are focusing on methanol anodic oxidation (MOR). In this work, nanoflower and hollow spherical NiO was synthesized by a simply hydrothermal method and then modified by Co ion, NiS2 and carbon nanotubes (CNTs). The optimal Co/NiO(f)/NiS2−CNT exhibits flower‐like morphology with a larger specific surface area, enlarged electrochemically active surface area and higher conductivity, which improve the electron transfer ability and electrocatalytic activity compared with pure NiO(f), NiO(f)/NiS2, NiO(f)/NiS2−CNT and hollow spherical Co/NiO(hs)/NiS2−CNT. The current density is ultrahigh of 203.46 mA ⋅ cm−2 at 0.8 V, which is 36 times higher than pure NiO(f) and almost 2 times higher than Co/NiO(hs)/NiS2−CNT. Therefore, this work offers a highly efficient and stable NiO based catalyst for methanol oxidation reaction.

“…The presence of Ni dopants may lead to alterations in the density and distribution of electronic states within the material, resulting in modifications to its optical response and refractive index. 40 Importantly, the increase in refractive index holds significant benefits for solar cell applications. A higher refractive index implies a stronger light-matter interaction, facilitating enhanced light trapping and absorption within the active layer of the solar cell.…”
