- W2089975089 abstract "Gold nanoparticles supported on MnO2–carbon nanocomposite (Au/MnO2–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 MnO2–carbon nanocomposite support. Cyclic voltammetry shows that the prepared Au/MnO2–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/MnO2–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 MnO2 towards glucose oxidation. MnO2–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." @default.
