1. A membrane-free electrochemical reactor, comprising:
a) a collection chamber disposed between a cathode chamber and an anode chamber, wherein said cathode chamber and said anode chamber are sealably connected to said collection chamber;
b) a mesoporous carbon paper cathode, and a mesoporous carbon paper anode, wherein said mesoporous carbon paper cathode is disposed between said cathode chamber and said collection chamber, wherein said mesoporous carbon paper anode is disposed between said anode chamber and said collection chamber, wherein said mesoporous carbon paper cathode is coated with an Oxygen Reduction Reaction (ORR) catalyst; wherein the ORR catalyst is positioned on a side of the mesoporous carbon paper cathode facing the collection chamber, wherein said ORR catalyst imparts a two-electron partial reduction reaction to hydrogen peroxide, wherein said mesoporous carbon paper anode is coated with an Oxygen Evolution Reaction (OER) coating; wherein the OER coating is positioned on a side of the mesoporous carbon paper anode facing the anode chamber;
c) an oxygen input port, and an oxygen output port, wherein said oxygen input port is connected to said cathode chamber, wherein said oxygen output port is connected to said cathode chamber;
d) a water input port, and a water output port, wherein said water input port is connected to said anode chamber, wherein said water output port is connected to said anode chamber, wherein said water input port and said water output port are in an open state;
e) a second water input port connected to said collection chamber; and
f) a hydrogen peroxide output port connected to said collection chamber.
