Unique Bi₄TaO₈Cl nanosheets were synthesized via a molten-salt method and then processed to introduce tunable oxygen vacancy (V_O) concentrations through H₂/Ar treatment and in situ NaBH₄-assisted calcination reduction, respectively. Owing to the surface polarization induced by the V_O, the modified BTOC exhibits significantly enhanced charge separation/transport efficiency and improved CO₂ activation capability. Consequently, the CO production rate increases substantially with the V_O concentration. Density functional theory calculations reveal that this enhancement originates from the role of V_O in regulating the local electronic structure and optimizing the adsorption free energy of the *COOH intermediate. This work provides theoretical insights and a practical strategy for designing high-performance, defect-regulated bismuth oxyhalide photocatalysts.

Spin-polarized In₂O₃ hollow spheres catalyze photo-enhanced CO₂ hydrogenation. Spin polarization reduces electron–hole recombination and enhances reactivity of surface intermediates.

Two Bi ₄ NbO ₈ Cl nanosheets with individually exposed (001) and (201) were synthesized for photocatalytic conversion of CO ₂ into CO and C ₂ H ₅ OH while only CO was produced on the bulk materials, and (201) typically accelerates the process of C–C coupling.

Fe₂O₃ nanorods were in situ synthesized in ambient air at room temperature by oxidation of Fe-based MOFs, which possess a high photocurrent density up to 0.11 mA cm⁻² and exhibit an outstanding oxygen evolution rate efficiency of 55.2 μmol g⁻¹ h⁻¹.

Employment of synergistic coassembly of a synthetic glycolipid N-(11-cis-octadecenoyl)-β-d-glucopyranosylamine (1) and silica allows us to create a series of complex silica architectures. 1 acts as both a structure-directing template and morphogen.

The corrosion resistance of magnesium alloys can be effectively improved by surface treatment. In this study, a hydrophobic two-dimensional (2D) TiO₂/MoS₂ nanocomposite coating was fabricated on AZ31B magnesium alloy by an electrophoretic deposition method. The corrosion resistance of the coating was evaluated using potentiodynamic polarization and electrochemical impedance spectroscopy analyses. After being modified by a silane coupling agent (KH570), the TiO₂/MoS₂ coating changed from hydrophilic to hydrophobic, and the static water contact angle increased to 131.53°. The corrosion experiment results indicated that the hydrophobic 2D TiO₂/MoS₂ coating had excellent anticorrosion performance (corrosion potential: E_corr = −0.85 V_Ag/AgCl, and corrosion current density: I_corr = 6.73 × 10⁻⁸ A·cm⁻²). TiO₂/MoS₂ films have promising applications in magnesium alloy corrosion protection.
