Surface Functionalization of Diamond and Its Electrochemical Application

Assistant Prof. Takeshi Kondo
Department of Pure and Applied Chemistry
Faculty of Science and Technology
 

Research Iterest:
 - Surface modification of diamond
 - Application of modified diamond electrodes to electroanalysis

1. Surface-Functionalized Diamond Materials

graph1
Diamond surface was functionalized with different types of chemical functionalities and nanoparticles. Some of these were applied to electrochemical analysis (oxalate, dopamine, hydrogen peroxide etc.) with high sensitivity.

2. Fabrication of New Types of Diamond Electrodes

graph1
Conductive diamond fibers, hollow fibers, transparent diamond electrodes,
conductive diamond powders, nano-structured diamond electrodes were
fabricated for wider application fields in electrochemistry.



Applications
Electrode materials for sensitive electrochemical detection of various analytes from metal ions in environment to bio-related organic compounds.

Advantages
Wide potential window and low background current enables sensitive detection of various analytes at low concentrations.
