Abstract
Official abstract text for this publication.
A cathode material comprising a titanium sheet and platinum, the platinum being in the form of nanoparticles deposited on at least one side of the titanium sheet, to form a decoration thereon, and processes for the preparation thereof.
First claim
Opening claim text (preview).
1 . A cathode material comprising a titanium sheet and platinum, the platinum being in the form of nanoparticles deposited on at least one side of the titanium sheet, to form a decoration thereon. 2 . A cathode material according to claim 1 , wherein the amount of platinum deposited on the at least one side of the titanium sheet is from about 0.00001 mg Pt/cm 2 Ti to about 1.0 mg Pt/cm 2 Ti, 3 . A cathode material according to claim 1 , wherein the nanoparticles of platinum have a mean particle size of 1 nm to 20 nm. 4 . A cathode material according to claim 1 , wherein the geometric area of the titanium sheet decorated with platinum is between about 1% and about 70% of the total geometric area of the titanium sheet. 5 . A method for producing a cathode material in accordance with claim 1 comprising depositing nanoparticles of platinum on to a titanium sheet by a pulsed electroplating method. 6 . A method for producing a cathode material in accordance with claim 1 , comprising depositing nanoparticles of platinum on to a titanium sheet by a nanoparticle deposition method. 7 . A method for producing a cathode material in accordance with claim 1 comprising depositing nanoparticles of platinum on to a titanium sheet by an accelerated nanoparticle deposition method. 8 . A method according to claim 7 , wherein acceleration voltages of from 1 kV to 5 kV, are employed. 9 . A cathode for a hydrogen evolution reaction in an electrochemical system, comprising a titanium sheet deposited with platinum nanoparticles on at least one side thereof, the platinum particles forming a decoration on the titanium sheet.
