Graphene sulfur doping

CVD graphene, which served as a counterelectrode in a dye-sensitized solar cell (DSSC), and, despite limited experimental details, showed good performance for triiodide to iodide reduction. Graphene decorated with NPs was also used in the development of bio-relevant sensors (Pd NP on rGO for detection of dopamine and diclofenac) [135] and as effective catalyst for ORR (Pt NP on sulfur-doped rGO) [136]. Iron NPs incorporated in a nitrogen-doped rGO were also studied and showed promise for ORR electrocatalysis [137].
