- W2082710924 abstract "An easy surface-modified method has been developed to link −NH2 groups to the TiO2 colloidal spheres with nanoporous surface (f-TiO2). It was found that the as-prepared f-TiO2 is positively charged in neutral conditions and could act as an electrostatic anchor for nanosructures with opposite charge. Furthermore, platinum nanoparticles (Pt NPs) are successfully assembled on the f-TiO2 mainly via electrostatic interaction to fabricate a new kind of Pt NPs/TiO2 hybrid nanomaterial (f-TiO2−Pt NPs). The morphology, structure, and composition of the hybrids were characterized by the means of diverse techniques such as transmission electron microscopy, scanning electron microscopy, X-ray powder diffraction, and Raman spectra. Electrochemical experiments indicate the electrode modified with f-TiO2−Pt NPs shows prominent electrocatalytic activity toward the oxidation of hydrogen peroxide. In particular, as an example, a glucose biosensor fabricated by casting on additional glucose oxidase containing a biocompatible polymer, chitosan on the f-TiO2−Pt NPs film exhibits great promise for sensitive and fast detection of glucose." @default.
