| Abstract: | A DNA-Ni2+ complex film was prepared by using direct electrodeposited method. The nickel ions immobilized in the DNA membrane exhibited an excellent and stable catalytic activity to the electro-oxidation of methanol. It was indicated that the DNA membrane would not block the methanol molecules diffuse into the catalytic active site in the membrane. Furthermore, it could make oxidation intermediate products which may poison the active site react sufficiently. As a result, the DNA membrane was an ideal carrier for the Ni ion immobilizing, and the utilization efficiency of catalysts Ni2+ could get higher. |
