Summary: Developing highly efficient electrocatalysts for the oxygen evolution reaction (OER) through heterojunction engineering and electronic structure modification has been recognized as a promising approach to enhance water splitting efficiency. In this study, ultralow Pt-loaded (1%) NiCoFeP@NiCoFe-PBA hollow nanocages with well-defined heterointerfaces and modified electronic environment were successfully fabricated. The obtained Pt-NiCoFeP@NiCoFe-PBA exhibited outstanding performance with a low overpotential of 255 mV at 10 mA cm-2 and a small Tafel slope of 57.2 mV dec-1, attributed to its highly open three-dimensional structure, exquisite interior voids, and abundant surface defects.

Summary: In this study, quasibound states in elliptical and circular graphene quantum dots were systematically investigated through experiments and theoretical calculations. It was found that bonding and antibonding molecular collapse states formed by two coupled atomic collapse states, and the antibonding state can change into a Klein-tunneling-induced quasibound state, revealing a deep connection between atomic collapse states and the Klein tunneling.

Summary: Regulating the transfer pathway of charge carriers in heterostructure photocatalysts is crucial for selective CO2 photoreduction. In this study, the charge transfer pathway in 2D MoS2/1D TiO2 heterostructure was successfully regulated by varying the light wavelength range, demonstrating its switchable property. Under simulated solar irradiation, charge transfer followed an S-scheme mechanism, while under visible light illumination, a heterojunction approach was observed. This research opens up possibilities for developing photocatalysts with switchable charge transport and tunable redox potential for selective artificial photosynthesis.

Summary: The study investigates the structural, electronic, and optical properties of the MoS2/MoSi2N4 heterostructure, finding that it has a smaller indirect bandgap and lower work function compared to individual monolayers. The heterostructure can enhance light absorption in both the ultraviolet and visible regions. The refractive index behavior of the HTS is described as a cumulative effect of the individual effects of the MoSi2N4 and MoS2 monolayers.

Summary: It has been found that the PEC performance of glycerol oxidation reaction (GOR) can be enhanced by using ZnIn2S4/ TiO2 heterostructure photoanode, which showed 1.7 folds improvement compared to pure TiO2 photoanode at 1.23 V vs. RHE. The ZnIn2S4/TiO2 heterostructure was simulated by constructing ZnIn2S4 on the TiO2 single crystal, which allowed for investigating the interface electronic structure. This study proposes the interface electronic structure of the ZnIn2S4/TiO2 heterostructure with a Z-scheme mechanism and provides a comprehensive strategy for analyzing the interface electronic structure of heterostructures.

Summary: This study aims to enhance the piezoelectric response of PVDF-based thin flexible nanogenerators by introducing 2D MoS2/1D TiO2 heterostructure as nanofillers. Among different nanogenerators, the 2D MoS2/1D TiO2 heterostructure-based nanogenerator shows the best performance due to the optimization of β phase content in PVDF matrix, leading to the highest peak to peak open circuit voltage, short circuit current, and instantaneous power density.

Summary: In this study, a Ru-MoS2 heterostructured catalyst was designed to address the challenges of low charge-separation efficiency and catalytic hydrogen evolution activity in photoelectrochemical water splitting for hydrogen evolution reaction. The engineered electronic structure of Ru-MoS2 significantly decreased charge transfer resistance and optimized electron transportation and Gibbs free energy of hydrogen adsorption, leading to enhanced catalytic HER efficiency. The n+p-Si/Ti/Ru-MoS2 photocathode demonstrated the largest reported photocurrent density for Si-based photocathodes and achieved a high solar-to-hydrogen conversion efficiency.

Summary: The mechanical and electronic properties of MoS2 can be tuned through aryl radical addition reactions. The density of the formed film is greater on single-layer MoS2 (SLM) compared to multilayer MoS2 (MLM) on Au(111) substrates. The films formed weakly bind to the SLM and MLM surfaces and easily wear away under contact forces, indicating limited covalent bonding.

Summary: In the current stage, conventional silicon-based devices face limitations in scaling and Fermi level pinning effect. Therefore, the search for low-resistance metal contacts for semiconductors, especially two-dimensional (2D) metal/semiconductor contacts, has become crucial. However, the practical applications of these contacts are hindered by the Schottky barrier and tunneling barrier. To address this issue, this work proposes a new strategy of constructing a donor-acceptor heterostructure, Ca2N/MoS2, to reduce the contact potential barrier. The results demonstrate excellent performance of n-type Ohmic contact formation between Ca2N and MoS2, as well as the potential for forming Ohmic contacts with other TMDCs like WS2, MoSe2, WSe2, and MoTe2.

Summary: The structural reconstruction-modulated electronic, polaronic, and excitonic properties of a non-layered oxide at the monolayer limit are uncovered in this study. The stable titanium dioxide (TiO2) monolayer is shown to have distinct surface Kagome sublattices with a topologically nontrivial flat band at the valence band edge. The monolayer TiO2 exhibits strong electron-lattice coupling, which results in the formation of small electron polarons and a reduced band gap energy into the visible light range.

Summary: This study reports a method for preparing nitrogen-doped titanium dioxide (N-TiO2) films with visible-light activity and improved transparency. By using pulsed magnetron sputtering, a high concentration of up to 7.5% nitrogen has been incorporated into anatase TiO2 films, resulting in a significantly reduced band gap of approximately 1.92 eV and remarkable photocatalytic performance in the visible-light range. Importantly, the transparency of the films does not decrease significantly even at high doping concentrations, unlike samples prepared using conventional direct current (DC) sputtering process. First-principles calculations reveal that the improved nitrogen incorporation at substitutional lattice sites is responsible for the reduced band gap and improved transparency. This work demonstrates a viable method to achieve transparent N-TiO2 films with visible-light activity, which could have various environmental applications such as self-cleaning glass.

Summary: In this study, a multi-layer TiO2-NTs/Sb-SnO2/PbO2 electrode was constructed for the electrochemical oxidation of ammonia nitrogen to N2. The electrode exhibited stable structure and efficient electrocatalytic activity, with outstanding stability and long life of 935 h. It displayed better performance of chlorine evolution and higher removal efficiency of ammonia compared to the commercial Ti/RuO2-IrO2 electrode. The electrode facilitated the transformation of ammonia nitrogen to gaseous nitrogen with high selectivity, while minimizing the formation of by-products like nitrite and nitrate. Overall, the multi-layer TiO2-NTs/Sb-SnO2/PbO2 electrode showed promise for electrochemical oxidation of ammonia nitrogen in aqueous solutions.

Summary: In this study, the synergistic activation of CoS2 and MoS2 (2H-MoS2 and 1T-MoS2) was found to greatly enhance the HER activity. The interfacial Co sites in 2H-MoS2/CoS2 and 1T-MoS2/CoS2 heterostructures exhibited low Gibbs free energies for hydrogen adsorption, even superior to Pt(111). Experimentally, MoS2/CoS2 showed reduced overpotential and lower Tafel slope under acidic and alkaline conditions. The improved performance was attributed to the synergistically activated interfacial Co atoms.

Summary: The electromechanical response in lead-free polycrystalline piezoelectric thin films is significantly enhanced by utilizing lattice-defect-induced structural inhomogeneities. The large electromechanical strain in a polycrystalline film integrated on silicon is achieved by inducing self-assembled Nb-rich planar faults with a nonstoichiometric composition.
