The ionic hydride react with water to produce hydrogen (Eq. (1)) [4].(1)MHx+xH2O→M(OH)x+xH2where M = metal of valence x. Production of hydrogen depends on the molar ratio of hydride to water. The H2 gas evolution from solid NaBH4 under various experimental conditions such as ...
If the reaction conditions are chosen so that all the oxygen vacancies react with water, it is possible to titrate these O vacancies by measuring the amount of hydrogen produced in the reaction [12]. Though titania was the reference oxide in most SMSI studies, other oxides may lead to ...
We synthesized water-soluble Au25(MHA)18 (6-mercaptohexanoic acid) NCs via such a two-step reduction process33. In the first reduction, HAuIIICl4 directly reacts with MHA ligands to form Au–MHA complexes under basic conditions. Those complexes are subsequently reduced using NaBH4 to form Au...

The generated [CoIIICoIV=O]+ was easier to be further oxidized to [CoIVCoIV=O]2+ intermediate which is react with water to form O–O bond via WNA pathway [24,25,66–68]. There is no direct experimental evidence for a [CoIIICoIII−OOH]+ intermediate, but such intermediates are ...
Anchoring single metal atoms on enzymes has great potential to generate hybrid catalysts with high activity and selectivity for reactions that cannot be driven by traditional metal catalysts. Herein, we develop a photochemical method to construct a stable single-atom enzyme-metal complex by binding sin...
In a Schlenk tube equipped with a stirring bar was charged with the TCCA (0.35 mol equiv.) and diselenide 2 (0.55 mol equiv.) in 1.0 mL of anhydrous ethanol and let to react for 5 min. After that, was added the respective (N-hetero)-arenes (0.25 mmol) and 1.0 mL of anhydrous eth...
