Abstract
The present disclosure provides for and includes electrocatalytic devices and methods for the production of Dry Hydrogen Peroxide (DHP), a non-hydrated, gaseous form of hydrogen peroxide.
Claims24
An electrocatalytic device for the production of dry hydrogen peroxide (DHP), said device comprising:
- a) an electrically conductive network coated with an electrocatalyst, wherein said electrocatalyst comprises one or more materials chosen from titanium dioxide, zinc oxide, iron oxide, or tungsten oxide;
- and
- b) a Modulated Alternating Current (MAC) electrical power source configured to provide an electric current and/or a voltage to said electrically conductive network,
- wherein said MAC electrical power source is configured to alternately initiate said electrocatalyst into a cathodic DHP operation mode and an anodic DHP operation mode by adjusting said electrical current and/or said voltage applied to said electrically conductive network,
- wherein during said cathodic DHP operation mode, said electrocatalyst acts as a cathode to generate DHP and wherein during said anodic DHP operation mode, said electrocatalyst acts as an anode to generate DHP,
- wherein said electrocatalytic device is configured to direct said DHP generated out of said electrocatalytic device and into a surrounding environment,
- wherein said electrically conductive network is an air permeable conductive network,
- wherein said air permeable conductive network comprises a meshwork or a conductive fabric, and
- wherein said air permeable conductive network has an electrocatalyst thickness of between 5 nm and 750 nm and an open area of between 10% and 60%.

An electrocatalytic device for the production of dry hydrogen peroxide (DHP), said device comprising:
- an enclosure including an inlet opening, an outlet opening, and a frame located between the inlet and outlet openings;
- an electrically conductive network at least partially coated with a catalyst to form a catalyst-coated electrically conductive network,
- wherein the electrically conductive network is formed from copper and wherein the catalyst comprises titanium dioxide,
- wherein the catalyst-coated electrically conductive network has a thickness of between 1 micron and 7 mm and an open area of between 10% and 60%,
- wherein the frame is configured to secure the catalyst-coated electrically conductive network between the inlet opening and the outlet opening such that air flowing between the inlet opening and the outlet opening during operation of the electrocatalytic device passes through the open area of the catalyst-coated electrically conductive network;
- and
- a modulated alternating current (MAC) electrical power source, wherein the MAC electrical power source is coupled to the electrically conductive network and configured to provide electrical power to the catalyst-coated electrically conductive network when the electrocatalytic device is in operation,
- wherein the catalyst-coated electrically conductive network, the inlet opening, and the outlet opening are arranged with a morphology that enables the removal of near-ideal gas phase DHP from the electrocatalytic device before the DHP is forced to undergo subsequent reduction or oxidation.
