Photo Induced Electron Transfer

A glycyrrhizin decorated graphene hybrid materials (GL-G) was synthesized, which is a layer-to-layer sandwich construction. The results of characterization indicate that a photo induced electron transfer process or efficient energy transferring along the GL-G interface. Furthermore, the as-made hybrid material was used as a modifier of the glassy carbon electrode to construct a sensor (GL-G/GCE). Using p-nitrophenol as a model compound, the novel sensor demonstrated a highly enhanced electrochemical activity for it. The peak current of p-nitrophenol was significantly improved at the sensor.

Proton Adsorption

Electrocatalytic properties of AMIM-Br-MWCNTs originate from a synergistic effect of covalent bond structure, in which AMIM-Br obtains the strongest proton adsorption ability, while the MWCNTs facilitates the electron-transfer process.
