Photocatalytic H2O2production via oxygen reduction represents a sustainable pathway for solar-to-chemical energy conversion. However, constructing sacrificial-agent-free heterojunctions that simultaneously maximize charge separation and preserve redox ability remains a significant challenge. Herein, we report a molecular-level interfacial engineering strategy to anchor COF-TpBpy onto CdSe nanorods via in-situ solvothermal growth, fabricating a strongly coupled organic–inorganic S-Scheme heteroju

Solar-driven H2O2production presents a sustainable alternative to the energy-intensive anthraquinone process, yet remains limited by inefficient charge transfer and poor selectivity. Herein, a synergistic strategy combining the atomic defect engineering and interfacial microenvironment modulation is established, which involves the in-situ mechanical growth of β-ketoenamine-linked covalent organic framework (TpBTD-COF) onto Zn single-atom-anchored sulfur-vacancy (Sv)-rich Sb2S3nanorods (Zn-Sv/Sb2

Engineering high-efficiency S-scheme heterojunctions with robust interfacial charge transfer channels is critical for simultaneously achieving spatial charge separation and preserving the strong redox potential of photogenerated carriers. Herein, we report the successful construction of a novel covalently integrated TpBpy/MIL-68(In) S-scheme heterostructure via an in situ solvothermal strategy. Uniquely, MIL-68(In) nanorods function as dynamic quasi-templates, in which partial structural dissolu

Overcoming rapid charge carrier recombination and restricted visible-light harvesting in single-component photocatalysts remains a formidable challenge for efficient solar-to-hydrogen conversion. In this work, an in situ self-assembly strategy is employed to construct a high-performance heterojunction by integrating zinc in dium sulfide (ZnIn2S4) nanoflowers with non-Ti3C2-type titanium carbonitride (Ti3CN) MXene nanosheets. The optimized 3 wt% Ti3CN/ZnIn2S4composite exhibits a remarkable visibl

This study underscores the critical role of phase engineering in boosting the photocatalytic hydrogen evolution performance of MoSe2-based heterostructures. The metallic (1T) and semiconducting (2H) phases of MoSe2were rationally synthesized and integrated with CdZnS nanorods to construct a 1T/2H-MoSe2/CdZnS hybrid photocatalyst. The optimized composite exhibits an exceptional H2evolution rate of 44.9 mmol·g-¹ ·h-¹ , representing a 5.4-fold enhancement over pristine CdZnS and significantly outpe

Covalent organic frameworks (COFs), characterized by efficient light absorption and highly tunable electronicstructures, exhibit substantial promise for photocatalytic hydrogen peroxide (H2O2) production. To solve theproblem of severe photogenerated carrier recombination, the researchers proposed to construct step-scheme (S-scheme)heterojunctions by combining COFs with metal sulfides (MS) to achieve effective separation anddirectional transfer of photogenerated electrons and holes. Herein, we de

The development of metal–organic framework (MOF)-based composites for photocatalytic hydrogen evolution has garnered significant attention due to their tunable structures, high surface area, and abundant active sites. Recent advancements focus on enhancing light absorption, charge separation, and catalytic efficiency through strategies such as ligand functionalization, metal doping, heterojunction formation, and plasmonic coupling effects. For instance, modifications with Ir (III) complexes and

Covalent triazine frameworks (CTFs) are a class of porous organic semiconductors containing a large number of triazine units, which gives them many properties suitable for photocatalysis, such as high porosity, good tunability, and excellent chemical stability. However, it is difficult to achieve high activity, stability, and selectivity at the same time using a single CTF in a specific catalytic reaction. Therefore, it is necessary to find ways to combine CTFs with other materials to improve th
