A direct glucose alkaline fuel cell using MnO 2-carbon nanocomposite supported gold catalyst for anode glucose oxidation
Gold nanoparticles supported on MnO 2-carbon nanocomposite (Au/MnO 2-C) are synthesised as the catalyst for the anodic oxidation of glucose for use in a direct glucose alkaline fuel cell (DGAFC). Characterisation of the catalyst is carried out using physical and electrochemical methods. It is observed that gold nanoparticles are uniformly dispersed onto the MnO 2-carbon nanocomposite support. Cyclic voltammetry shows that the prepared Au/MnO 2-carbon catalysts exhibit higher electro-catalytic activity for glucose oxidation than that of commercial Pt/C and Au/C catalysts. A maximum power density, at 30 °C, of 1.1 mW cm -2 is obtained using an Au/MnO 2-C anode catalyst in DGAFC, which is higher than that of the commercial Au/C catalyst. The enhanced activity is attributed to a catalytic effect of MnO 2 towards glucose oxidation. MnO 2-C nanocomposite is a promising approach for reducing noble metal catalyst loading in addition to improving the catalytic activity of gold catalyst for glucose oxidation.

Abstract
Gold nanoparticles supported on MnO 2-carbon nanocomposite (Au/MnO 2-C) are synthesised as the catalyst for the anodic oxidation of glucose for use in a direct glucose alkaline fuel cell (DGAFC). Characterisation of the catalyst is carried out using physical and electrochemical methods. It is observed that gold nanoparticles are uniformly dispersed onto the MnO 2-carbon nanocomposite support. Cyclic voltammetry shows that the prepared Au/MnO 2-carbon catalysts exhibit higher electro-catalytic activity for glucose oxidation than that of commercial Pt/C and Au/C catalysts. A maximum power density, at 30 °C, of 1.1 mW cm -2 is obtained using an Au/MnO 2-C anode catalyst in DGAFC, which is higher than that of the commercial Au/C catalyst. The enhanced activity is attributed to a catalytic effect of MnO 2 towards glucose oxidation. MnO 2-C nanocomposite is a promising approach for reducing noble metal catalyst loading in addition to improving the catalytic activity of gold catalyst for glucose oxidation.
