Abstract
The present invention concerns a method for the preparation of a catalyst onto a solid support of a (semi-)conductive material consisting in depositing said catalyst onto said support from a near-neutral aqueous solution containing at least one nickel or cobalt organic complex and at least one basic oxoanion, by a method selected in the group consisting of reductive electrodeposition, photochemical electrodeposition and photoelectrochemical deposition. The present invention also concerns said catalyst and uses thereof.
Claims18
A method for the preparation of a catalyst onto a solid support of a conductive or semiconductive material, the method comprising:
- depositing said catalyst onto said solid support from a near-neutral aqueous solution containing at least one nickel or cobalt organic complex and at least one basic oxoanion, using a method selected from the group consisting of reductive electrodeposition, photochemical electrodeposition, and photoelectrochemical deposition,
- wherein the catalyst consists of elemental cobalt/nickel covered or coated by a cobalt/nickel oxo/hydroxo-oxoanion layer.
