Title:
電気化学的処理方法及び電気化学的処理装置
Document Type and Number:
Japanese Patent JP4190173
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electrode for electrochemical treatment, which can decompose even a deleterious material requiring a high potential for decomposition, and provide an electrochemical treatment method and an electrochemical treatment apparatus. SOLUTION: The electrode includes a doped diamond layer 2 which covers the surface of a conductive substrate 1, and a non-doped diamond layer 3 which further covers the whole surface or a part of the surface of the layer 2. The doped diamond layer 2 has a diamond composition doped with impurity atoms having concentration of 5×10<19> cm<-3> or more. The non-doped diamond layer 3 has such an extremely low impurity content that the atom concentration of elements except carbon is 5×10<17> cm<-3> or less. Such a structure promotes a chemical reaction of a material to be treated on the surface of the electrode, because of transporting electric charges, which are injected from the surface of the doped diamond layer 2 into the non-doped diamond layer 3, to the surface of the non-doped diamond layer 3 while accelerating them in the non-doped diamond layer 3.
