1. A method of producing hydrogen peroxide using nanostructured bismuth oxide, comprising the steps of:
immersing an anode and a cathode in an alkaline solution saturated with oxygen in an electrolytic cell, the cathode being a conducting substrate having a surface layer of nanostructured oxygen-deficient bismuth oxide of formula Bi2O3-x, wherein x is greater than 0 and less than 3;
establishing an electrical potential across the cathode and the anode to initiate reduction of the oxygen at the cathode, thereby producing hydrogen peroxide.
