Synthesis and electrocatalytic properties of microsized Ag2WO4 and nanoscaled MWO4 (M=Co, Mn)
Source abstract
Abstract
Microstructured Ag2WO4 with shuttle-like shape was synthesized via a precipitation process with assistance of Arabic gum. MWO4 (M=Co and Mn) nanocrystals were prepared facilely via a hydrothermal procedure. The as-prepared samples were identified and characterized by X-ray diffraction, transmission electron microscopy, and scanning electron microscopy, respectively. The resultant samples were used directly as electrocatalysts modified on a glassy carbon electrode for p-nitrophenol, K2CrO4 and H2O2 reduction in a basic solution. The results showed that all peak currents increased markedly but the corresponding peak potential decreased by using CoWO4, MnWO4 and Ag2WO4 in turn by comparing to a bare glassy carbon electrode, and Ag2WO4, CoWO4 and MnWO4 exhibited enhanced electrocatalytic activity for p-nitrophenol reduction. Ag2WO4 also showed effective electrocatalytic activity for K2CrO4 and H2O2 reduction, but both CoWO4 and MnWO4 almost displayed very weak electrocatalytic properties for K2CrO4 and H2O2 reduction in basic solution.
