Graphical abstract
The paper reported synthesis of nitrogen and sulphur-functionalized multiple graphene aerogel (N,S-MGA) through simple multiple gel method. The resulting N,S-MGA exhibits a much higher density and electronic conductivity when compared with classical graphene aerogel. Owing to significant synergy between the electrode reaction of N,S-GMA and the redox reaction of K3Fe(CN)6, N,S-GMA electrode in the mixed redox electrolyte displays ultra high supercapacitor performance. | Exploring Graphene Quantum Dots/TiO2 interface in photoelectrochemical reactions: Solar to fuel conversion Original Research Article Electrochimica Acta, Available online 12 November 2015, Pages P.

Graphical abstractATPMnG was used to modify glassy carbon electrode (GCE) and investigate the electrocatalytic oxidation features of Ascorbic Acid (AA) by Cyclic voltammetry (CV) and differential pulse voltammetry (DPV). These results show the oxidation peak current of AA at the ATPMnG/GC electrode have a large shift negatively and the intensity of the oxidation peak current increased significantly compared with that at the bare GCE, which illustrate a quite good catalytic activity for oxidation of AA at the ATPMnG/GC electrode. The oxidation mechanism of AA has been discussed.
