Abstract
- Electrocatalytic glucose oxidation reaction (GOR) has attracted much attention owing to its crucial role in biofuel cell fabrication. Herein, we load MoO<subscript>3</subscript> nanoparticles on carbon nanotubes (CNTs) and use a discharge process to prepare a noble-metal-free MC-60 catalyst containing MoO<subscript>3</subscript>, Mo<subscript>2</subscript>C, and a Mo<subscript>2</subscript>C–MoO<subscript>3</subscript> interface. In the GOR, MC-60 shows activity as high as 745 µA/(mmol/L cm<superscript>2</superscript>), considerably higher than those of the Pt/CNT (270 µA/(mmol/L cm<superscript>2</superscript>)) and Au/CNT catalysts (110 µA/(mmol/L cm<superscript>2</superscript>)). In the GOR, the response minimum on MC-60 is as low as 8 µmol/L, with a steady-state response time of only 3 s. Moreover, MC-60 has superior stability and anti-interference ability to impurities in the GOR. The better performance of MC-60 in the GOR is attributed to the abundant Mo sites bonding to C and O atoms at the MoO<subscript>3</subscript>–Mo<subscript>2</subscript>C interface. These Mo sites create active sites for promoting glucose adsorption and oxidation, enhancing MC-60 performance in the GOR. Thus, these results help to fabricate more efficient noble-metal-free catalysts for the fabrication of glucose-based biofuel cells. [ABSTRACT FROM AUTHOR]
