Summary: In this work, a one-step ammonia nitridation process was proposed to embed noble metal Ir nanoparticles into the Ni3N nanosheet structure. The Ir-Ni3N heterogeneous interface was established on the surface of the nickel foam substrate. The results showed that the IrOx/NiOOH heterogeneous interfaces formed after self-reconstruction played a significant role in promoting the oxygen evolution reaction, with an overpotential of only 273.3 mV at a current density of 10 mA cm-2. This work also demonstrated the stability and efficiency of Ir-Ni3N as an electrocatalyst for hydrogen evolution and overall water splitting.

Summary: Nickel-based materials have great potential as platinum-group-metal-free electrocatalysts for hydrogen oxidation reaction in alkaline solution. However, the sluggish kinetics limited their electrocatalytic activity. To accelerate the kinetics, heterostructures and nitride structures have been developed. In this study, the authors combined these two methods to synthesize sheet-like Ni3N/MoO2 in-plane heterostructures, which showed significantly enhanced activity for hydrogen oxidation reaction in alkaline electrolytes.

Summary: The sluggish kinetics of the hydrogen evolution reaction (HER) in alkaline media can be overcome by using a catalyst consisting of metallic Ni on Fe-doped MoOx nanosheets (Ni/FeMoOx) to promote water dissociation. The Ni/Fe-MoOx catalysts exhibit better HER performance than Ni/MoOx catalysts, requiring lower overpotentials to achieve the same current densities. This is attributed to the stronger water dissociation ability caused by Fe doping, which provides more available protons in the alkaline medium. Furthermore, Fe doping enhances the oxygen evolution reaction (OER) performance of the catalysts, resulting in a low cell voltage and excellent stability in a water splitting device.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
