International Journal of Electrochemical Science, 2014 H4SiW12O40 (abbreviated as SiW) and Pt supported on carbon nanotubes (CNTs) with different Pt/SiW ratios were prepared and characterized by FTIR, XRD, ICP-OES, polarography, and TEM. The prepared catalysts were then after attached onto glassy carbon (GC)
