Photocatalytic Reduction of Water to Hydrogen overPt, Eosin YCatalysts, Sio
of water and hydrogen peroxide in ORR has a strong size dependence. Instead, the onset potentials increase monotonically with size to Pt10. They found that the branching between 4e−reduction to water and 2e−reduction to H2O2is strongly size-dependent with the smallest Ptnapparently giving ...
In this paper, we report on the photoelectrochemical hydrogen evolution reaction (HER) from water using Rhodium-doped strontium titanate, surface-modified by the addition of minute amounts of platinum nanoparticles. Platinum has been used in an attempt to increase the charge transfer efficiency of ...
Manganese oxides are ubiquitous marine minerals which are redox sensitive. As major components of manganese nodules found on the ocean floor, birnessite and buserite have been known to be two distinct water-containing minerals with manganese octahedral&n
to Pt-N-C and Pt-S-C, giving rise to a controlled H2O2selectivity from 23.3% to 81.4% and a turnover frequency ratio of H2O2/H2O from 0.30 to 2.67 at 0.4 V versus reversible hydrogen electrode. Energetic analysis suggests both 2e−and 4e−pathways share a common intermediate of ...

respectively. The 4 mg of the catalysts and 80 μl of Nafion (5 wt%) as a binding material were dispersed in 1 ml ofsolvent(water/isopropanol = 3:1 v/v) and the mixture was sonicated for 30 min to form a catalyst inkslurry. Then, 14 μl of the ink slurry was...
This complete lack of axial ligand coordination coupled with the hydrophobicity of the residue makes the blue copper center in fungal laccase possess one of the highest reduction potentials. In addition to the above two factors, other factors, such as solvent exposure242 and hydrogen bonding ...
Besides material balances several chemical reactions occur in the process. Water is split into hydrogen and oxygen in theelectrolyserand iron ore is reduced tosponge ironin the shaft. The reactions considered in the electrolyser and the reduction shaft are shown in equations ...
A process for preparing silicon carbide by carbothermal reduction is disclosed. This process involves rapidly heating a particulate reactive mixture of a silica source and a carbon source to form a pr
