Abstract
Official abstract text for this publication.
The present disclosure is directed to electrocatalytic devices having an electrodeposited MO x /ICP composite thin films for performing oxygen reduction reactions.
First claim
Opening claim text (preview).
What is claimed is: 1 . An oxygen reduction reaction device, comprising: a composite film, comprising: a homogeneously dispersed composite film consisting essentially of a plurality of manganese oxide particles dispersed in an intrinsically conductive polymer that is a component of a cathode of an electrocatalytic device; wherein the intrinsically conductive polymer is selected from a group consisting of PEDOT and ProDOT; wherein the homogeneously dispersed composite film is formed by electrodeposition of the manganese oxide particles with the PEDOT or ProDOT to homogeneously disperse the manganese oxide particles in the intrinsically conductive polymer to form a composite film consisting of MnO 2 and PEDOT or ProDOT; and wherein the composite film performs an oxygen reduction reaction. 2 . The device of claim 1 , further comprising a substrate. 3 . The device of claim 1 , wherein the device is an electrode. 4 . The device of claim 3 , wherein the electrode is a cathode. 5 . The device of claim 1 , wherein the composite film is a cathode that is part of a system selected from the group consisting of batteries, fuel cells, electrolyzers, hydrogen evolution reaction devices. 6 . The device of claim 1 , wherein the manganese oxide particles are nanoparticles. 7 . The device of claim 1 , wherein the manganese oxide particles are MnO 2 particles.
