Understanding iron-oxide as a photo-catalyst for the oxidation half of the water splitting reactionSustained solar-driven water splitting to make dihydrogen must also include the formation of dioxygen. Many researchers view hematite (伪-Fe2O3) as a potentially attractive photocatalytic anode for ...
In this work, we report that light-induced oxidative half-reaction of water splitting is effectively integrated with the reductive coupling of aryl bromides in the presence of the activated Pd/g-C3N4(named as Pd/g-C3N4*) and Na2CO3, which provides a method for using green water as the red...
With the emergence of more and more catalysts for water oxidation, researchers found that under the harsh reaction conditions, some molecular catalysts may transform to heterogeneous metal oxides/hydroxides. Since metal oxides/hydroxides have been reported to be active for catalytic oxidation of water,...
For scavenging CB electrons, the former case commonly uses Ag(I) ions as an electron scavenger to promote oxidative reaction pathways4, whereas the latter case applies a potential that is more positive than the onset potential to draw electrons out of the photoelectrode5. Regarding the effects ...
Oxidation treatment is one of the most common methods to introduce oxygen-containing functional groups on the surface of carbon materials, including chemical and electrochemical oxidation (Fig. 3). Chemical oxidation is a chemical reaction between oxidants and carbon materials to achieve an oxidation mo...
H Kühne,GW Brudvig - 《Journal of Physical Chemistry B》 被引量: 103发表: 2002年 The role of proton coupled electron transfer in water oxidation Water oxidation is a key half reaction in energy conversion schemes based on solar fuels and targets such as light driven water splitting or carbo...
The authors concluded that the spallation of the oxide proceeds during cooling and assumed a dissociation reaction of water molecules at the specimen surface leading to the formation of OH− and H+ ions, which may further react with the alloy. These dissociation products according to equation ...
This work clearly demonstrates the use of an MIS Si photoelectrode for the water-oxidation half reaction, and therefore does not satisfy the thermodynamic requirement for the overall water-splitting reaction. To successfully realize a spontaneous water splitting, the photoanode should be combined with ...
Finally, a possible reaction mechanism was proposed. This new nanometer-size Co-ZIF catalyst will be applied well in the selective oxidation of toluene to benzaldehyde. Keywords: selective oxidation; benzaldehyde; nanometer-size catalyst; MOFs material...
The ozonation combined with UV-radiation (O3/UV) is an efficient catalytic system for the degradation of refractory pollutants in wastewater. The process is initiated by the photolysis of ozone and followed by the production of OH• radicals by the reaction of O• with water [19]. The syn...
