Peroxide power: Neutral solutions of H2O2 can be produced directly and safely from O2 and H2 by using a fuel cell reaction. The most active and efficient cathode is a vapour-grown carbon fibre (VGCF) electrode coated with Co-tetraphenylporphyrin (0.05 wt %) on VGCF (2 mg cm...
Define H2o2. H2o2 synonyms, H2o2 pronunciation, H2o2 translation, English dictionary definition of H2o2. n. A colorless, heavy, strongly oxidizing liquid, H2O2, capable of reacting explosively with combustibles and used principally in aqueous solution as

Here we present an efficient approach for nitrogen oxidation, substituting the oxygen evolution reaction with hydroxyl radicals (·OH) generated through hydrogen peroxide decomposition to serve as an active oxygen source. Electrochemical tests demonstrate that the nitrogen oxidation, facilitated by ·OH, ...
The chemical energy from a fuel can be also converted into electricity through a chemical reaction with oxygen or another oxidizing agent driven by various types of fuel cells [5], [6]. Since a kind of hybrid cells generated by a combination of dye-sensitized solar cell with fuel cell has...

The aforementioned core–shell nanocatalyst synthetic strategies entail the use of a single shell material; however, this approach might present limitations in complex reaction systems that demand diverse enhancement of activities. Therefore, we propose the use of two elements in the shell to simultaneou...
The reaction was then initiated by applying the selected potential with constant O2 bubbling, and TTC degradation was monitored over time. The results are shown in Figure 8. As expected, all samples are active in the EF process, which is attributed to the capability of samples to produce ·...
Although a rich variety of POs-based catalysts have been developed by tuning the complex composition, a highly efficient PO catalyst that is able to alter the reaction pathway from a 4e− process to a 2e− process for H2O2 production has rarely been achieved. We modified the structure and...
