Summary: Amorphous chromium oxide confined Ni/NiO nanoparticles-assembled nanosheets were synthesized through an in-situ confined synthesis method, which showed fast reaction kinetics for urea oxidation reaction (UOR). The confinement effect of the in-situ generated CrOx overlay resulted in ultrafine Ni/NiO nanoparticles and rich interfaces. Both CrOx and metallic Ni promoted the formation of NiOOH species and electron transfer, leading to high intrinsic activity and fast reaction kinetics. The protective effect of the CrOx overlay also ensured robust working stability for UOR. Moreover, the Ni/NiO@CrOx nanosheets served as bifunctional catalysts for overall urea splitting with a low electrolysis cell voltage.

Summary: This study aims to enhance the efficiency of ethanol electrooxidation reaction (EOR) and overcome electrode fouling by electrodepositing ternary nanocomposites of copper, nickel, and iron oxides on the glassy carbon electrode (GCE) surface. The GCEs were modified using three different procedures and activated by CV cycling in an alkaline solution. The best electro-catalytic efficiency was achieved by simultaneously electrodepositing nano Cu, Ni, and Fe2O3 on the GCE surface.

Summary: Ammonia (NH3) is a versatile clean energy source with high energy density and hydrogen content. However, the sluggish kinetics of the NH3 electro-oxidation reaction (AOR) poses challenges in both direct NH3 fuel cells and NH3 electrolysis. This review focuses on the fundamentals of AOR and recent progress in catalyst modifications, particularly Pt- or Ni-based electrocatalysts, to enhance reaction kinetics and overcome limitations. The findings of this review will be valuable in proposing new robust electrocatalysts for advanced AOR in practical applications.

Summary: This study investigated the evolution of the active surface composition for nickel-selenide and -telluride-based electrocatalysts by intentionally creating nickel-oxide-coated surfaces. The results confirmed the stability of the catalytically active chalcogenide surfaces in alkaline medium, providing evidence that the surface evolves into a mixed anionic (hydroxo)chalcogenide surface. The study also highlighted the significant differences in electrochemical properties between oxide-coated, selenide, and telluride surfaces, emphasizing the importance of understanding the composition changes in chalcogenide surfaces using electrochemical properties.

Summary: Establishing a platform with different nanostructured oxides is a novel idea for developing highly sensitive and selective sensing devices. The study successfully created 3D-heterostructures consisting of 1D nanowires of NiO and WO3, exhibiting selective behavior towards different gases. The improved sensing performance of the heterostructures is attributed to charge carrier transport through specific interfaces and modulation of charge carriers in the electron depletion layer of WO3 and hole accumulation layer of NiO and NiWO4.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
