Ultrafine platinum nanoparticles are grown on a 3D graphene framework (GF–Pt) via a hydrothermal method. The material, when placed on a glassy carbon electrode (GCE), displays enhanced electrocatalytic activity towards glucose oxidation. This is assumed to be the result of the numerous easily accessible active sites, an enlarged electrochemically active area, and the presence of multiple electron/ion...
A green but efficient synthesis approach for chlorine-doped reduced graphene oxide (Cl-RGO) was developed. The chlorine-doping and reduction was achieved in one-step by refluxing graphene oxide solution in concentrated hydrochloric acid (8 M, 120 °C) under N2 atmosphere. X-ray photoelectron spectroscopy analysis revealed that the Cl content was 1.01 at.% in the Cl-RGO. Electrochemical measurements...
Chloramphenicol (CAP), as a broad-spectrum antibiotic, has been worldwide banned for using in the food producing animals due to its overuse may cause severe threats to public health. It is therefore highly desirable to develop facile, selective and sensitive biosensor for CAP detection and monitoring in drug and foodstuff samples. In this work, three-dimensional reduced graphene oxide (3DRGO) architectures...
