Based on the literatures reported here, the development of highly stable visible鈥搇ight-active photocatalytic materials, and the design of efficient, low-cost photoreactor systems are the key for the advancement of solar-hydrogen production via photocatalytic water splitting in the future....
Solar water splitting holds great promise for hydrogen production but is significantly hindered by rapid recombination of photogenerated charges. Now a metal–organic framework photocatalyst has been shown to undergo, upon photoexcitation, a dynamic excited-state structural twist that greatly suppresses char...
Functionalized vesicles for photocatalytic hydrogen production in water have been prepared by co-embedding of amphiphilic photosensitizers and a hydrogen-e... S Troppmann,B König - 《Chemistry》 被引量: 24发表: 2015年 Photocatalytic Hydrogen Production using Polymeric Carbon Nitride with a Hydrogenas...
The Mn0.25Cd0.75S/MoS2 composites synthesized by single step hydrothermal method reported for hydrogen production from water splitting under visible-light irradiation. It shows better efficiency than Mn0.25Cd0.75S because the interfacial layer between Mn0.25Cd0.75S and MoS2 accelerates the electron ...
Moreover, highly efficient sulfide photocatalysts for solar hydrogen production in the presence of electron donors were developed by making solid solutions of ZnS with AgInS2 and CuInS2 of narrow band gap semiconductors. Thus, the database of powdered photocatalysts for water splitting has become ...
The conversion of oxygen and water into hydrogen peroxide was found to occur via a metastable two-electron water oxidation and two-electron oxygen reduction pathway. The CNIO-GaSA photocatalyst exhibits a high reactivity of 331.7 μmol g−1 h−1 for H2O2 production, with a solar-...
are sustainable, others are not and may be toxic or environmentally damaging. Applying environmental catalysis in three main areas: water and soil remediation, biomass valorization, product upgrading, and biofuel and hydrogen production can provide valuable insights for achieving global environmental ...
The present work is a short review of our recent studies on PhotoFuelCells, that is, photoelectrochemical cells which consume a fuel to produce electricity or hydrogen, and presents some unpublished data concerning both electricity and hydrogen production. PhotoFuelCells have been constructed using nan...
Unfortunately, we are not there yet. Even if the systems work and have been under stable operation for a few months, we are currently talking about efficiency levels of around one percent. This is, of course, still too low. Our aim is to achieve hydrogen production efficiency of between fi...
