摘要

Intrazeolite copper dicyanoanthraquinone diimines (NaY/Cu(DCNAQI) were synthesized within NaY zeolite using a "ship-in-a-bottle" technique. These particles were subjected to CV and EIS characterizations based on their associated particulate electrodes. Analysis of the EIS over a wide range of frequency and at potentials around the formal potential of DCNAQI0/- showed that the charge transfer resistance and the double layer capacitance in the equivalent circuit based on the Fletcher transmission lines were sensitive to the probing potential and the concentration of the free DCNAQI coexisting in the electrolyte solutions. Although CV does not provide much information about the influence of hydrogen on NaY/Cu(DCNAQI), the EIS characterizations suggested hydrogen can significantly accelerate the charge transfer kinetics for most NaY/Cu(DCNAQI) particles.
