TiO2–Au composite nanofibers for photocatalytic hydrogen evolution

Photocatalytic Property of TiO2-Vermiculite Composite Nanofibers via Electrospinning

Titanium dioxide (TiO2) is one of the most common photocatalysts. In this study, TiO2-vermiculite composite nanofibers with a mesh structure and a diameter of approximately 300 nm were prepared via sol-gel approach combined with electrospinning technique. The samples were characterized by X-ray diffraction, scanning electron microscopy, ultraviolet-visible spectroscopy, etc. The photocatalytic ...

Extended conjugated microporous polymers for photocatalytic hydrogen evolution from water.

Conjugated microporous polymers (CMPs) have been used as photocatalysts for hydrogen production from water in the presence of a sacrificial electron donor. The relative importance of the linker geometry, the co-monomer linker length, and the degree of planarisation were studied with respect to the photocatalytic hydrogen evolution rate.

Graphene/Semiconductor Nanocomposites: Preparation and Application for Photocatalytic Hydrogen Evolution

Photocatalytic hydrogen evolution through fully conjugated poly(azomethine) networks.

Three-dimensional conjugated poly(azomethine) networks were found to be promising candidates for applications in photocatalytic water splitting. Straightforward synthetic protocols lead to fully organic photocatalysts that showed enhanced long-time stability. Furthermore, the catalytic performance of these materials was correlated to the molecular composition and the optoelectronic properties o...

Ammonia-induced robust photocatalytic hydrogen evolution of graphitic carbon nitride.

We report a new and effective method to prepare high activity graphitic carbon nitride (g-C3N4) by a simple ammonia etching treatment. The obtained g-C3N4 displays a high BET surface area and enhanced electron/hole separation efficiency. The hydrogen evolution rates improved from 52 μmol h(-1) to 316.7 μmol h(-1) under visible light.
