Characterization of Diamond Electrode Deposited on a Porous Active Carbon Pellet
摘要
Abstract
Active carbon pellet as substrates for the deposition of diamond films were prepared by chemical vapor deposition (CVD). The ballas diamond morphologies of the as-deposition films were analyzed by scanning electron microscopy. Raman spectroscopy was used to investigate the crystal structure. The electrochemical behavior of a boron-doped diamond film electrode prepared on porous active carbon substrates was studied by cyclic voltammetry and AC Impedance. The diamond films exhibited a ballas morphology and contained microcrystallites. The potential windows in acidic, neutral or alkaline medium were respectively 4.4 V, 4.0 V and 3.0 V. In the electrolyte including Ferri/Ferrocyanide, the electrode surface kept good activity, and the electrochemical reaction occurring on the surface was a diffusion-controlled reaction, with good quasi-reversibility.关键词
