“…Meanwhile, the peaks at 861.7 and 879.9 eV originate from spin−orbiting binary satellites. 37,38 Figure 4d shows the S 2p spectrum, the two peaks at 162.3 and 163.8 eV with the binding energies of S 2p 3/2 and S 2p 1/2 , respectively. This result indicates the presence of metal−sulfur bonds in Ni 3 S 2 @CuAg-10.…”

Direct methanol fuel cells (DMFCs) have captured increasing attention as promising renewable energy devices. The development of innovative, cost-effective electrocatalysts with superior performance for the methanol oxidation reaction (MOR) holds great significance in promoting DMFCs. In this study, a facile dealloying−electrodeposition method was employed to fabricate stereospecific Ni 3 S 2 nanoflowers on a three-dimensional nanoporous CuAg substrate (Ni 3 S 2 @CuAg) for accelerating MOR. The nanoporous CuAg alloy substrate was prepared by dealloying of the metallic glassy (MG) alloy precursor, and the Ni 3 S 2 nanoflowers were in situ grown on the nanoporous CuAg skeleton through a simple electrodeposition process. The novel Ni 3 S 2 @CuAg catalysts exhibit outstanding catalytic performance for MOR owing to their preeminent conductivity, large specific surface area, and abundant active reaction sites. Notably, the optimal Ni 3 S 2 @CuAg-10 exhibited a superior current density of 340.5 mA cm −2 at 1 V along with good stability (93% current density retention after 2 h) in 1 M KOH and 1 M CH 3 OH solution. This work presents a novel strategy for designing electrocatalysts with high efficiency and durability for MOR.

“…For instance, Liu et al [11] prepared a porous microstructure on AZ31 magnesium alloy using the micro-arc oxidation method, and then modified the samples using a stearic acid ethanol solution to attain superhydrophobicity. Yin et al [12] combined electrochemical deposition and hydrothermal treatment to construct a nanorodlike superhydrophobic coating on stainless steel. The prepared coating possessed good self-cleaning properties and could degrade organic molecules under ultraviolet radiation, thereby preventing the damage from organic pollutants in practical conditions [12].…”

This study develops the nanostructured superhydrophobic titanium-based materials using a combined preparation method of laser marking step and the subsequent anodizing step. The structural properties were determined using an X-ray diffractometer (XRD) and scanning electron microscope (SEM), while the performance was explored by wear and corrosion tests. The laser marking caused a rough surface with paralleled grooves and protrusions, revealing surface superhydrophobicity after organic modification. The anodizing process further created a titanium oxide (TiO2) nanotube film. Both phase constituent characterization and surface elemental analysis prove the uniform nanofilm. The inert nanosized oxide film offers improved stability and superhydrophobicity. Compared to those samples only with the laser marking process, the TiO2 nanotube film enhances the corrosion resistance and mechanical stability of surface superhydrophobicity. The proposed preparation pathway serves as a novel surface engineering technique to attain a nanostructured superhydrophobic surface with other desirable performance on titanium alloys, contributing to their scale-up applications in diverse fields.
