چکیده

The design and construction of low-cost high-performance hybrid materials for the photocatalytic hydrogen production reaction (HER) are extremely important large-scale application energy. Metal-organic frameworks (MOFs) considered to be potential materials. Herein, monodisperse, small size, non-precious metal transition phosphide Ni2P is encapsulated into a typical MOF (UiO-66-NH2) as core-shell cocatalyst modify Zn0.5Cd0.5S production. wrapped in UiO-66-NH2 via an situ solvothermal method, sulfide decorated with Ni2[email protected]2 obtain ternary protected]2/Zn0.5Cd0.5S composite Photoelectric chemical characterization confirms that composites have good kinetic performance. rate 10% 10 mg reaches 40.91 mmol·g–1·h–1 apparent quantum efficiency at 420 nm 13.57%. addition increases surface area material, providing abundant sites forming efficient charge transfer channel, which conducive by photocatalysts. It shown formation system beneficial occurrence catalytic reaction. This study provides new perspective

Ternary 3D architectures of CdS QDs/graphene/ZnIn2S4 heterostructures for efficient photocatalytic H2 production.

Highly efficient hydrogen production can be achieved by three-dimensional (3D) architectures of CdS quantum dots (QDs) incorporated in the porous assembly of marigold-like ZnIn2S4 heterostructures coupled with graphene, leading to an efficient electron transfer between them and the enhancement of the ZnIn2S4 photostability. The as-prepared samples were characterized by X-ray diffraction, electr...

New Superhard Ternary Borides in Composite Materials

Superhard substances are those a hardness above 20 GPa, i.e. higher than that of corundum (Kislii et al.,1988) or with a Vickers hardness Hv exceeding 40 GPa (Sologenko&Gregorianz, 2005). The ten utmost non-metal substances and refractory compounds form a "hardness pyramid" (Kislii et al.,1988) diamond being on top, followed by cubic-boron nitride and boron carbide. Metal-like ones form a simil...

The facile synthesis of mesoporous g-C3N4 with highly enhanced photocatalytic H2 evolution performance.

Mesoporous g-C3N4 has been obtained by a facile sucrose-mediated approach via thermal condensation of sucrose and melamine for the first time. The mesoporous g-C3N4 presents a much higher BET surface area and displays highly enhanced photocatalytic H2 evolution performance.

Photocatalytic H2 production from water with rhenium and cobalt complexes.

Photocatalytic hydrogen production in pure water for three component systems using a series of rhenium-based photosensitizers (PS) and cobalt-based water reduction catalysts (WRC), with triethanolamine (TEOA) as an irreversible electron donor, is described. Besides the feasibility of this reaction in water, key findings are reductive quenching of the excited state of the PS by TEOA (k(q) = 5-8 ...
