| DWPI Title: Oxygen reduction reaction device comprises composite film, comprising homogeneously dispersed composite film consisting essentially of manganese oxide particles dispersed in intrinsically conductive polymer that is component of cathode of electrocatalytic device |
| Abstract: The present disclosure is directed to electrocatalytic devices having an electrodeposited MOx/ICP composite thin films for performing oxygen reduction reactions. |
| Use: Oxygen reduction reaction device. |
| Advantage: The oxygen reduction reaction device improve MnOx conductivity and oxygen reduction reaction (ORR) activity by hybridizing manganese oxide (MnOx) nanoparticles with an intrinsically conductive polymer (ICP), such as, but not limited to poly(3,4-ethylenedioxythiophene) (PEDOT). According to an embodiment, hybrid PEDOT/MnOx nanoparticle films were prepared by organic electropolymerization of the 3,4-ethylenedioxythiophene (EDOT) monomer, followed by room temperature, aqueous growth of MnOx nanoparticles. |
| Novelty: Oxygen reduction reaction device comprises a composite film, comprising: a homogeneously dispersed composite film consisting essentially of multiple of manganese oxide particles dispersed in an intrinsically conductive polymer that is a component of a cathode of an electrocatalytic device, where the intrinsically conductive polymer is selected from a group consisting of poly(3,4-ethylenedioxythiophene) (PEDOT) and propylenedioxythiophene (ProDOT). 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 manganese dioxide (MnO2) and PEDOT or ProDOT, and the composite film performs an oxygen reduction reaction. |
