The Hall-Heroult process of aluminum production is featured by the release of CO2as a result of the sacrificing graphite anode. Finding a proper inert anode active in oxygen evolution has been a research topic for electrochemists to have a green process of aluminum electrolysis. A thin layer of diamond coating on silicon substrate has shown some promises. The challenges for the project are two folds, fabricating stable and active diamond electrode, and controlling proper electrolysis condition so as not to degrade the diamond thin film. This paper reports the recent findings from the authors' lab dealing with both challenges.
