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,...
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...
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 water-in-salt electrolytes, we systematically altered the water activity, which enabled us to ...
Electrocatalysis constitutes the core process of abundant sustainable energy systems such as fuel cells, rechargeable metal-air batteries, and water splitting1,2,3. However, classical electrochemical reactions (for instance, oxygen evolution reaction (OER), oxygen reduction reaction (ORR), hydrogen evolut...
reaction of chlorine with organic matter or in the presence of bromide [14]. Furthermore, residual chlorine may impair the drinking water quality due its possibly perceptible taste and odor. Permanganate on the other hand does neither promote the formation of toxic disinfection byproducts, nor ...
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 ...
Urea electrooxidation, an ideal substitute, is thus received increasing attention in assisting water-splitting reactions. Note that highly efficient catalysts are still required to drive urea oxidation, and the facile generation of high valence state species is significant in the reaction based on the ...
Understanding the function of surface states on photoanodes is crucial for unraveling the underlying reaction mechanisms of water oxidation. For hematite photoanodes, only one type of surface states with higher oxidative energy (S1) has been proposed and verified as reaction intermediate, while the othe...
