Iridium-based electrocatalysts are the most promising candidates for acidic oxygen evolution reaction (OER). Considering their high cost and scarcity, it is imperative to maximize atom utilization enhance intrinsic activity of iridium. In this work, IrOx sub-2 nm clusters stabilized on TiO2 supports via metal support interaction (MSI) induced by vacancy defects in TiO2. The strength MSI readily tuned type vacancies: vacancies (VO-TiO2) induce adsorbed with relatively weak strength, while...
Wrinkled Ir-doped manganese oxide (Ir-MnO x ) nanospheres have been prepared via a facile metal–organic framework-directed strategy as pH-universal OER electrocatalysts.
Using the non-equilibrium Green's function formalism in combination with density functional theory, we calculated spin-dependent electronic properties of molecular devices consisting pristine and hydrogen-terminated zigzag gallium nitride nanoribbons (ZGaNNRs). Computational results show that proposed ZGaNNR models display multiple functions perfect spin filtering, rectification, a negative differential resistance (sNDR) effect. Spin-dependent transport properties, transmission pathways...
Visible-light driven photocatalytic hydrogen production from water is a hotspot in renewable energy.
Recent experiments have shown that the photocatalytic activity of g-C3N4 can be greatly enhanced by C60 modification, however, a fundamental understanding its mechanistic operation is still lacking. Using first-principles calculations, interfacial effects C60/g-C3N4 nanocomposites on electronic properties, charge transfer and optical response been explored in detail. For different stacking patterns, two constituents are always linked van der Waals (vdW) forces without any exception, form...

Vertical van der Waals (vdW) heterostructures made up of two or more 2D monolayer materials provide new opportunities for devices. Herein, we study the electronic transport properties vertical integration GeSe-phosphorene(GeSe–BP) heterostructure, using nonequilibrium Green's function formalism combined with density-functional theory.

2D layered SiC/C<sub>2</sub>N type-II heterostructure is an effective photocatalyst for hydrogen production from water splitting by visible light.
Biaxial strain can effectively regulate the band edges and alignments of BlueP/γ-SnS heterostructures, thus achieving high solar-to-hydrogen efficiency in both Z-scheme type-I heterojunctions under compressive strains.
Graphene has been recognized as a promising candidate in developing tunable terahertz (THz) functional devices due to its excellent optical and electronic properties, such high carrier mobility conductivity.

The electronic structures of C/B/Al-doped armchair GaN nanoribbons (aGaNNRs) are systematically studied by using density functional theory. We find that the original aGaNNRs direct band gap semiconductors and gaps monotonically decrease with increasing widths. Interestingly, B- or Al-doped also direct-band a slightly larger than their undoped aGaNNRs, while C-doped display metallic characteristics an impurity state across Fermi level in structures. semiconducting behaviours can be explained...
