Article Abstract
Bimetallic zeolite-imidazole frameworks with controllable flat band position, band gap and hydrogen evolution reaction characteristics were adopted as a photocatalytic hydrogen production catalyst. Furthermore, the g-CN-MoS 2D-2D surface heterostructure was introduced to the ZnM-ZIF to facilitate the separation as well as utilization efficiency of the photo-exited charge carriers in the ZnM-ZIFs. On the other hand, the ZnM-ZIFs not only inhibited the aggregation of the g-CN-MoS heterostructure, but also improved the separation and transport efficiency of charge carriers in g-CN-MoS. Consequently, the optimal g-CN-MoS-ZnNi-ZIF exhibited an extraordinary photocatalytic hydrogen evolution activity 214.4, 37.5, and 3.7 times larger than that of the pristine g-CN, g-CN-ZnNi-ZIF and g-CN-MoS, respectively, and exhibited a H-evolution performance of 77.8 μmol h g under UV-Vis light irradiation coupled with oxidation of HO into HO. This work will furnish a new MOF candidate for photocatalysis and provide insight into better utilization of porous MOF-based heterostructures for hydrogen production from pure water.

Suppressing photoinduced charge recombination represents a critical challenge in photocatalytic ammonia (NH) decomposition for hydrogen (H) production. Herein, we propose a dual-cocatalyst system comprising plasmonic silver (Ag) and nickel oxide (NiO), which synergistically construct an Ag → titanium dioxide (TiO) → NiO directional electron cascade on TiO surfaces through work-function-induced interfacial charge transfer. The optimized 3 %Ag-1 %NiO-TiO reaches a significantly photocatalytic H production rate of 2366.

Solar-driven hydrogen peroxide (HO) production offers a green and sustainable alternative to the energy-intensive anthraquinone process, utilizing water and oxygen as feedstock and solar energy as the sole input. Covalent organic frameworks (COFs), owing to their well-defined crystalline structures and tunable electronic properties, have emerged as a compelling platform for photocatalytic HO synthesis. However, the efficiency of HO photosynthesis remains limited by sluggish charge separation and rapid carrier recombination.

Hydrogen evolution reaction (HER) driven by solar energy has attracted considerable attention due to its outstanding efficiency, environmental compatibility, and sustainability. Regrettably, the sluggish progress of the HER and the limitations in charge separation efficiency impede its practical photocatalysis. Herein, a two-step electrostatic self-assembly approach is adopted to construct NiO/CdMnS/TiCT (NO/CMS/TCT) ternary heterojunction with bidirectional carrier channels for boost photogenerated separation and oriented carrier accumulation.

Producing olefins by carbon dioxide (CO) hydrogenation is a long-standing goal. The usual products are multicarbon mixtures because the critical step of heterolytic hydrogen (H) dissociation at high temperatures complicates selectivity control. In this study, we report that irradiating gold-titanium dioxide at 365 nanometers induces heterolytic H dissociation at ambient temperature.

Organic semiconductors are very attractive photocatalysts for the production of solar fuels. However, their development is greatly plagued by limited visible light absorption and severe restriction of photoexcited charge carrier separation and transfer caused by the exciton effect resulting from inherent dielectric constraints. Herein, a three-motif molecular junction hydrogen evolution photocatalyst is constructed by linking a donor-acceptor-donor (D-A-D) molecule integrating the photosensitizer unit and the redox unit with holey carbon nitride sheets (HCNS) as a second electron acceptor unit (A) based on the covalent strategy.
