POROUS DIAMOND LAYER, METHOD FOR PRODUCING POROUS DIAMOND PARTICLE AND ELECTRODE FOR ELECTROCHEMISTRY USING THEM

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a diamond electrode having fine pores more than those of the conventional diamond layer, and having high electrode activity.

SOLUTION: Metallic particles deposited on a diamond layer are heat-treated in a reducing gas atmosphere, thus carbon reduction reaction with the above metal as a catalyst is progressed, and fine pores are formed on the surface of the diamond layer. Since the metal particles carried on the surface of the diamond layer is utilized, the diamond layer and diamond particles in which the fine pores are formed on an atomic level or a level close to the same can be obtained.
