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...
The introduction of ultrasound waves into the water creates a hot spot thus increasing the temperature of the liquids, which leads to the thermal decomposition of the water solution into the reactive radical species. The chain reaction generated at the gas-liquid interface can be written as (Ince...
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 ...
O-O bond formation is a key elementary step of the water oxidation reaction. However, it is still unclear how the mechanism of O-O coupling depends on the applied electrode potential. Herein, using …
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 ...
The reaction is initiated by irradiating the solution with a Xe lamp (λ≥ 420 nm, 100 mW/cm2) through a transmission glass filter under intense magnetic stirring at room temperature, and the mechanism of the visible-light-driven water oxidation is described in Scheme S1. 3. Results and ...
Lavoisier’s theory that combustion was a reaction between the burning substance and the gas oxygen, present only to a limited extent in the atmosphere, was based on scientific principles, the most important of which was the law of the conservation of matter (after Einstein’s relativity theory...
