Abstract
The invention relates to a process for electrolysis comprising a cathode and an anode comprising a catalyst, both the cathode and anode at least partly immersed in an electrolyte, the process characterised in that the electrolyte at least partly inhibits further oxidation of a product formed at the anode. Typically the catalyst comprises one or more metal-(Group VIb) semiconductors, and one or more metal-(GroupVIb))-phosphorous species.
Claims11
A process for water electrolysis comprising:
- providing a cathode and an anode, the anode containing a catalyst,
- providing an electrolyte,
- immersing both the cathode and anode at least partly in the electrolyte, and
- selectively transforming water at the anode to hydrogen peroxide or radicals capable of forming hydrogen peroxide,
- wherein the electrolyte at least partly inhibits further oxidation of the hydrogen peroxide formed at the anode,
- wherein the catalyst comprises one or more metal-(GroupVlb))-phosphorous species,
- wherein the one or more metal-(Group Vlb)-phosphorous species satisfies the formula M′m′A′a′Py wherein:
- M′ is a metal,
- A′ is a Group Vlb species,
- m′ and a′ have a value of between 1 and 5,
- P is a phosphorous species, and
- y has a value 0<y <5.
