    Abstract Perylene diimides (PDI) are widely used in photocatalytic oxygen evolution due to their deep valence band potentials. Here, we report the synthesis of a unique supramolecular photocatalyst (designated s-PDI-P1) by introducing hydroxyl and carboxyl groups at the imide position of PDI. This modification allows the formation of intermolecular double hydrogen bond structures between the hydroxyl groups, oxygen atoms on the perylene cores and the carboxyl groups. The resulting double hydrogen bonding structures reduce lateral slip and promote the formation of supramolecular structures with H-type π-π stacking. In addition, the intermolecular hydrogen bonding interactions between the hydroxyl groups and the oxygen atoms on the perylene cores bring the PDI molecules closer together, enhancing the conjugation of the PDI supramolecules and facilitating the formation of ultrathin nanosheet-like structures. In this study, we successfully constructed ultrathin nanosheets of the supramolecular photocatalyst s-PDI-P1 with a compact H-type π-π stacking structure, which exhibited enhanced charge transfer capability, shorter charge migration distance, and achieved a high photocatalytic oxygen evolution rate of 3.23 mmolg

    Abstract Rapid heat loss and fast charge carrier recombination constitute two crucial issues that hinder the development of efficient solar energy utilization and conversion over the semiconductor in a photothermal catalytic system. Inspired by energy production from waste water, we designed an advanced 3D C@TiO₂ multishell nanoframe (MNF) photocatalyst. Its unique structural features of heat confinement and vibrant photocarrier kinetics lead to excellent photo-thermal conversion for synchronous superior photocatalytic H₂ evolution (503 μmol g⁻¹h⁻¹) and 98.2% RhB removal without the use of any co-catalyst and sacrificial reagent under simulated sunlight irradiation (AM 1.5G). Mechanism exploration reveals that the difference between the inner and outer gas pressure formed inside C@TiO₂ precursor facilitates the selective cleavage of outer TiO₂ layers at selected temperatures during calcination. Synergistic effects between residual carbon core and multi-shelled TiO₂ framework endow C@TiO₂ MNF with excellent heat confinement and vibrant photocarrier kinetics. Such MNF photo-thermocatalyst concept provides a novel strategy for effective utilization of solar energy, and this work may open a novel avenue towards advanced nanostructures for efficient waste-to-energy conversion.

    Abstract There are significant challenges in developing technologies for high-yield photocatalytic hydrogen production reactions. Current photocatalytic materials face three key problems: low utilization of light, rapid recombination of photogenerated electron-hole pairs, and a limited number of active sites during photocatalytic reactions. As a result, these materials only improve one or two of the three steps involved in photocatalytic hydrogen production reactions. Consequently, achieving simultaneous multifunctional synergy to enhance the efficiency of all three processes is difficult. Here, we report an in situ dissolution-recrystallisation approach to design and fabricate a three-dimensional TiO

    Abstract Herein, disorder–order TaON homojunction photocatalysts with different concentrations of surface oxygen vacancies were prepared by a simple and novel aluminothermic reduction method. The surface oxygen vacancy defects disrupt the periodicity of the crystal surface and weaken the crystallinity of TaON particles, resulting in a crystalline core and an amorphous shell structure. Introduction of oxygen vacancy plays a pivotal role in regulating the band structure and charge kinetic behaviors of TaON. It renders not only the appearance of defect band level in the forbidden band, which allows drastically broadened and enhanced light absorption of TaON particles, but also the formation of the disorder–order TaON homojunction, which increases the concentration of photogenerated carriers, inhibits the recombination of photogenerated charge and promotes effective surface photocatalytic reaction, thus resulting in significantly improved photocatalytic hydrogen production activity of TaON photocatalyst. The aluminothermic reduction temperature for optimum photocatalytic activity of TaON was 400 °C, giving a hydrogen production activity of 25 μmol g⁻¹ h⁻¹, about twice as pure TaON under visible light. This work could shed light on exploring oxygen vacancy-activated photocatalytic materials with great potential for solar-energy conversion.

    Abstract Exfoliating bulk graphite phase carbon nitride (g-C₃N₄) into 2D nanosheets is considered to be an effective method to enhance its photocatalytic activity. However, optical absorption capacity of the exfoliated g-C₃N₄ nanosheets are lower than that of the original bulk g-C₃N₄ due to the quantum size effect. Here, the ultrathin graphite phase carbon nitride nanosheets containing both carbon vacancy and cyano group (UCNS₅₈₀) were prepared by two-step calcination in air with the assistance of KOH. The formation and position of carbon vacancy and cyano group were first investigated and determined. The simultaneous introduction of carbon vacancy and cyano group not only improved light absorption range and intensity of g-C₃N₄ nanosheets, but also more importantly constructed a fast transfer channel for photogenerated electrons, further enhancing the separation efficiency and migration ability of photogenerated carriers. The cyano group as the accumulation center of photogenerated electrons and the oxygen adsorption center increased the proportion of one-step two-electrons reaction path to efficiently generate H₂O₂. As a result, UCNS₅₈₀ exhibited highly boosted H₂O₂ generation activity, its H₂O₂ production yield for 6 h reached 939 µmol/L and the formation rate was up to 4167 µM h⁻¹ g⁻¹, which was in priority in the reported literature under the same conditions.
