ELECTROSYNTHESIS OF HYDROGEN PEROXIDE Russian patent published in 2010 - IPC C25B1/30 

FIELD: electricity.

SUBSTANCE: method for production of hydrogen peroxide includes the following stages: provision of electrochemical cell, which comprises anode and cathode; contact of cathode with electrolyte, which contains at least one organic mediator dissolved in at least partially organic solid liquid phase, containing at least partially organic salt and neutral cosolvent, reaction of organic mediator on cathode with production of at least one reduced form of this mediator; and reaction of mentioned at least one reduced form of mediator with oxygen to form hydrogen peroxide. Besides partially organic salt contains at least one type of organic cation and/or organic anion, mentioned solid liquid phase has electric conductivity with method conditions that make approximately 0.1 Cm/m.

EFFECT: production of hydrogen peroxide by mediated electrochemical reduction of oxygen without necessity in contact of cathode with gaseous hydrogen, which may be realised at comparably simple equipment and includes electrochemical reduction of mediator.
