Özet
Highly arranged porous anodic titania (TiO2) nanotube arrays (ATNT) were fruitfully fabricated by the anodization of Ti foil in an ammonium fluoride electrolyte. Then, the CuO/Cu nanoparticles were consistently decorated onto the porous ATNT surface through electrochemical deposition and afterward impregnated into graphene oxide (GO) aqueous solution to produce CuO/Cu/GO-ATNT, which was then electrochemically reduced to form CuO/Cu/rGO nanocomposite ATNT electrode. The microstructures, morphologies, and chemical elements were investigated using XRD and FESEM techniques linked with EDS and XPS, respectively. The as-fabricated CuO/Cu/rGO nanocomposite ATNT electrode was utilized for non-enzymatic glucose sensing in a neutral electrolyte and exhibited superior electro-catalytic activity compared with the pristine and CuO/Cu nanoparticle ATNT electrodes. The electrocatalysis performance of the recommended CuO/Cu/rGO nanocomposite ATNT electrode was inspected and optimized. The experimental results exposed an effective amperometric electrode of glucose acquired under 0.6 V vs. Ag/AgCl with an excellent sensitivity of (371.6 mu A mM(-1) cm(-2)), a low detection limit (22.8 mu M), and a wide linear range from 0.5 mM to 16 mM (R-2 = 0.9992). This designed non-enzymatic glucose biosensor demonstrated high stability, reproducible, and selective biosensor. Hence, this endorses its promising technique for the detection of glucose samplers for clinical and pharmaceutical diagnoses.
