Summary: The electronic structures and photocatalytic properties of a 2D g-C3N4/Ti2CO2 van der Waals heterostructure were investigated using hybrid density functional theory. The heterostructure exhibited a staggered type-II band alignment with significant charge transfer, resulting in a built-in electric field at the interface. It demonstrated a direct Z-scheme photocatalytic mechanism, high catalytic activity towards hydrogen evolution and water oxidation reactions, and excellent light-harvesting capability with entire visible light absorption. These findings provide insights into Z-scheme photocatalysts and future designs of 2D vdW heterojunctions as high-performance catalysts.

Summary: The MnPSe3 monolayer with two nonequivalent energy valleys has attracted attention. The spin degeneracy is maintained in MnPSe3 due to antiferromagnetic coupling, but vdW heterostructures can induce spin splitting. We simulated the MnPSe3/GeC vdW heterostructure and found that the interlayer coupling effect can modulate the spin and valley splitting through stacking and vertical strain.

Summary: A facile hydrothermal method was used to construct TiO2/SrTiO3 heterojunction at the atomic scale, ensuring efficient charge separation for improved photocatalytic water splitting. The sample with a hydrothermal reaction time of 60 min exhibited the highest H2 evolution rate due to the efficient charge separation of the TiO2/SrTiO3 heterojunction. Furthermore, the sample showed the best overall water splitting performance at a hydrothermal reaction time of 120 min, where TiO2 was nearly converted to SrTiO3, resulting from the fast kinetic process and low structural defects of SrTiO3.

Summary: Janus niobium oxydihalide (NbOXY) is a multifunctional anisotropic semiconductor with exceptional properties in piezoelectricity, photocatalysis, optoelectronics, and sustainable energy applications. It exhibits stable and flexible monolayers with a band gap in the visible light regime. NbOXY has an exceptionally high anisotropic carrier mobility and large deformation potential, making it suitable for strain sensing applications. It also demonstrates strong piezoelectricity in both in-plane and out-of-plane directions, as well as strong optical absorption and linear optical dichroism in the visible-to-ultraviolet regime. Its compatibility with water splitting and high absorption peaks in the deep UV regime make it a promising material for solar-to-hydrogen conversion. Our findings highlight the exceptional potential of NbOXY for various functional device applications.

Summary: Bimetallic sulfides composed of highly dispersed Cu-doped ZnS composites were proposed as catalysts for photocatalytic H2 evolution. These catalysts exhibited an optimal H2 evolution activity of over 1569 μmol/g at pH = 3 and 2 hours of visible light irradiation, without the consumption of sacrificial agents or cocatalysts. The introduction of Cu into the ZnS lattice resulted in a narrower energy bandgap and a nonequilibrium charge distribution, which enhanced the absorption of visible light and facilitated the separation and migration of photoinduced carriers.

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.
