Abstract
Herein, we report the synthesis of several magnetic carbon structures starting from spheres (CSs) to more elongated structures to get tubes and fibers by customizing chemical vapour deposition parameters. These CSs-based products, ranging from nano-to micro-size, were investigated by morphological point of view using scanning electron microscopy, energy dispersive x-ray spectroscopy, and Raman spectroscopy. These carbon structures were combined with screen-printed electrodes highlighting their electrochemical effectiveness towards the detection of several species, i.e. ferricyanide, ascorbic acid, dopamine, cysteine, serotonin, and NADH. The presence of iron nuclei within the carbonaceous lattices, besides having improved the electrochemical performances at the printed electrodes, might confer these CSs-based structures a future application in the field of remediation/sensing. Herein, some preliminary applications were provided showing that these materials can be easily employed to collect species and, successively, coupled with printed electrochemical sensors.File | Dimensione | Formato | |
