This paper introduces the preparation of needle-shaped cuprous oxide (Cu2O) particles 3-10 nm in diameter and 40-150 nm in length on multiwall carbon nanotubes (MWNTs) by anodic oxidation of copper electrode in alkaline solution. Steady-state concentration of H2O2 as high as 0.42 mM is produced in aqueous suspension of nanosized Cu 2O/MWNTs composites illuminated by simulated solar light in the presence of formate and oxygen. Assisted by Fe2+-EDTA, these photogenerated H2O2 can be used as Fenton reagent; hydroxyl radicals have been detected ind...
