Wet-chemical-cum-reduction synthesis of CoOx/PbO2 at room temperature and its electrocatalytic application
E-mail:
A combination of potential widening and electrocatalyst bimetallic oxide CoOx/PbO2 was chemically synthesized at room temperature for the first time. Nano-metals of Pb and Co were synthesized by using NaBH4 in presence of surfactant solution, then the respective metal oxides made by addition of NaOCl. Analyses results obtained by XRD, SEM, TEM, XPS, UV-Visible, and FTIR indicated the resulting products were PbO2 and CoOx. The mixed CoOx/PbO2 oxide prepared in this manner demonstrated a crystalline morphology. CoOx/PbO2 mixed oxides with different Co to Pb ratios were investigated to understand whether the prepared CoOx/PbO2 oxides are in guest/host stack arrangement. XRD, XPS, and TEM analyses of at a Pb to Co ratio of 1:1 ratio revealed the formation of bimetallic oxides of CoOx/PbO2 and rod like morphology of pure CoOx turned to spherical like morphology with PbO2 demonstrated CoOx as guest of PbO2ㆍFor CoOx/PbO2 produced at higher Co to Pb ratios CoOx dominated the surface, meaning PbO2 was a guest of CoOx. The described optimized method provides a straightforward, convenient way of synthesizing nano-mixed metal oxides at low temperature.
