A membrane-free electrochemical reactor and fuel-cell having a collection chamber between a first and second chamber, a mesoporous carbon paper cathode between the first chamber and the collection chamber, a mesoporous carbon paper anode between the second chamber and the collection chamber, the cathode is coated with an oxygen reduction reaction catalyst that imparts a two-electron partial reduction reaction to hydrogen peroxide, the anode is coated with an oxygen evolution reaction coating or a hydrogen oxidation reaction coating, oxygen/air input and output ports connected to the first chamber, KOH/water input and output ports connected to the second chamber that are in an open state under an electrolyzer mode, H/water input and output ports connected to the second chamber that are in an open state under a fuel-cell mode, a second KOH/water input port connected to the collection chamber, and a hydrogen peroxide/KOH/water output port connected to the collection chamber.

Electrochemical hydrogen peroxide generating device

A method of fabricating polyacrylonitrile (PACN) nanostructured carbon superstructure shapes is provided that includes forming a PACN polymer superstructure shape by using as a monomer, an initiator, and a solvent or incorporation of a different co-monomer for free radical polymerization, and converting the PACN polymer superstructure shape to a nanostructured carbon superstructure analogue using stabilization and carbonization of the PACN polymer superstructure shape, where the stabilization includes heating the PACN polymer superstructure shape to a temperature that is adequate to form a stabilization reaction, where the carbonization includes using a heat treatment.
