Abstract
Official abstract text for this publication.
The electrochemical method of producing hydrogen peroxide using a titanium oxide nanotube catalyst is an electrochemical process for producing hydrogen peroxide using a cathode formed as a nanostructured titania (TiO 2 ) electrode surface treated with nitrogen. An anode and the cathode are immersed in an alkaline solution saturated with oxygen in an electrolytic cell. An electrical potential is established across the cathode and the anode to initiate electrochemical reduction of the oxygen in the alkaline solution to produce hydrogen peroxide dissolved in the alkaline solution. The hydrogen peroxide dissolved in the alkaline solution is then collected from the cell.
