Synthesis and characterization of proton-conducting materials containing dodecatungstophosphoric and dodecatungstosilic acid supported on silica

Solid electrolytes formed by different amounts of phosphotungstic acid (PWA) and silicotungstic acid (SiWA) in silica gel have been prepared and characterized. XRD, IR and DTA analyses performed on the samples in powder form revealed the existence of an interaction between the heteropoly acids and t...
