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...
متن کاملAmmonia-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.
متن کاملPolyoxoniobate-based 3D framework materials with photocatalytic hydrogen evolution activity.
Two phosphoniobate-based 3D frameworks were firstly constructed using the hexa-capped Keggin polyoxoniobates [PNb12O40(VO)6](3-) and copper cations. Photocatalytic studies indicated that the hybrid materials exhibit photocatalytic hydrogen evolution activity.
متن کاملEfficient photocatalytic hydrogen evolution over hydrogenated ZnO nanorod arrays.
Hydrogenated ZnO nanorod arrays (NRAs) grown on F-doped SnO(2) (FTO) glass substrates yield a benchmark specific hydrogen production rate of 122,500 μmol h(-1) g(-1), and exhibit excellent stability and recyclability.
متن کاملExtended 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.
