An electrochemical sensor is described for simultaneous voltammetric determination of dopamine (DA) and uric acid (UA). It is based on the use of a nanomaterial composed of gold nanoparticles and 3-dimensional graphene (Au NP@3D GR). The 3D GR was prepared by chemical vapor deposition using nickel nanoparticles as the template at a temperature of around 900 °C. The surface of 3D GR contains oxygen-functional...
Carbon nanofiber (CNF) was prepared by electrospinning using polypropylene and nickel was coated on the CNF by electroless plating. Then, graphene (Gr) was synthesized on the surface of nickel by chemical vapor deposition. After etching nickel, the Gr/CNF was obtained eventually and then used as a working electrode for the determination of levodopa in the presence of uric acid by cyclic voltammetry...
Nickel powders were prepared by the liquid phase reduction method. Using the nickel powders as the template, three-dimensional graphene foam (3D GF) was prepared via chemical vapor deposition (CVD) at high temperature, followed by acid etching. It was transferred onto the indium tin oxide (ITO) glass (3D GF/ITO) and acted as the electrode for the simultaneous determination of dopamine (DA) and uric...
A three-dimensional (3D) continuous and interconnected network graphene foam (GF) was synthesized by chemical vapor deposition using nickel foam as a template. The morphologies of the GF were observed by scanning electron microscopy. X-ray diffraction and Raman spectroscopy were used to investigate the structure of GF. The graphene with few layers and defect free was closely coated on the backbone...
