Facile fabrication of a non-enzymatic nanocomposite of heteropolyacids and CeO2@Pt alloy nanoparticles doped reduced graphene oxide and its application towards the simultaneous determination of xanthine and uric acid

A new nanocomposite was fabricated by combining 12-heteropolyacids (PMo6W6) and CeO2 decorated by Pt nanoparticles and RGO. Enhanced electrocatalytic activity and sensing performance were achieved due to the synergistic effect of components in nanocomposite. The proposed PMo6W6/RGO-CeO2@Pt is promising material for simultaneous or individual detection of xanthine and uric acid in practical application.334
