Herein, the preparation of CoSe@NiSe@MoS composites and the systematic investigation of their water splitting performance as a function of composition have been demonstrated. CoSe@NiSe@MoS-12 with the optimized composition exhibits a current density of 10 mA cm at overpotentials of 81 and 170 mV for HER and OER in alkaline conditions, respectively. The overall water splitting device built using CoSe@NiSe@MoS-12 exhibited a low voltage of 1.48 V at 10 mA cm due to the synergistic effects.

Tumor hypoxia and heat resistance as well as the light penetration deficiency severely compromise the phototherapeutic efficacy, developing phototherapeutic agents to overcome these issues has been sought-after goal. Herein, a diradical-featured organic small-molecule semiconductor, namely TTD-CN, has been designed to show low exciton binding energy of 42 meV by unique dimeric π-π aggregation, promoting near-infrared (NIR) absorption beyond 808 nm and effective photo-induced charge separation. More interestingly, its redox potentials are tactfully manipulated for water splitting to produce O and reduction of O to generate O .

As a future fuel, obtaining hydrogen from water could be a game changer for the renewable energy sector, because it has the potential to be used as an alternative to fossil fuels. The current project has been designed to develop catalysts that can produce hydrogen from water on irradiation by sunlight. For this purpose, CdS, Cu/CdS, Pd/CdS, and Cu-Pd/CdS catalysts were successfully synthesised and utilized for hydrogen generation.

Hydrogen is increasingly acknowledged as a viable alternative to traditional fossil fuels. However, the photothermal properties of CoFeS, a photocatalyst displaying metal-like behavior, have not been adequately explored in the context of photocatalytic H generation. To improve photocatalytic hydrogen evolution, it is crucial to understand how to expedite the transfer of photogenerated electrons and the dissociation of H-OH bonds for enhanced hydrogen ion release.

The development of suitable support to maximize the atomic utilization efficiency of platinum is of great significance for the hydrogen evolution reaction (HER). Herein, we report a simple and fast nonequilibrium-corrosive approach to prepare oxygen defect-enriched FeO decorated with trace Pt onto nickel-iron foam (Pt/FeO-O/NIF). The Pt/FeO-O/NIF electrode is superhydrophilic with intimate contact with the electrolyte.

Amidst the escalating global energy crisis, the quest for efficient electrocatalysts for water splitting has become increasingly imperative. Herein, we develop a bifunctional electrocatalyst comprising RuNi alloy nanoparticles anchored on fluorine-doped NiMoO nanorods (RuNi-F-NiMoO), engineered for efficient hydrogen production from seawater and urea oxidation reactions. The strategic F doping effectively reduces the difference in work functions and modulates the electronic interactions between the RuNi alloy and the NiMoO substrate, enhancing electron transfer kinetics and significantly improving electrocatalytic activity and stability.
