An Enzymatic Ethanol/O2 Biofuel Cell Powered By Commercial Vodka Fuel, Yi-Ming Yan, Lan-Qun Mao
Journal of Electrochemistry
This study demonstrates the performance of a new type alcohol/O2 biofuel cell assembled by using alcohol dehydrogenase (ADH) and bilirubin oxidase (BOD) as the biocatalysts of the bioanode and the biocathode for the bioelectrocatalytic oxidation of alcohol and reduction of oxygen, respectively. To construct the bioanode and the biocathode, single-walled carbon nanotubes (SWCNTs) were used. In the bioanode, SWCNTs were used as the supporting materials for both methylene green (MG) which was used as the electrocatalyst for the oxidation of NADH and ADH. The as-constructed MG/ADH/SWCNTs-based bioanode exhibits a good activity toward the bioelectrocatalytic oxidation of ethanol. In the …

Preparation And Properties Of Titanium Based Metal Oxide Electrodes For Ammonia Nitrogen Wastewater Treatment, Xue Li, Meng Xue, Ling Huang, Jun-Tao Li, Shi-Gang Sun
Journal of Electrochemistry
In this paper, four types of titanium based metal oxides electrodes were prepared by thermal decomposition method: Ti/SnO2+Sb2O3, Ti/SnO2+Sb2O3/SnO2+IrO2, Ti/SnO2+Sb2O3/SnO2+RuO2, Ti/SnO2+Sb2O3/SnO2+CeO2. The XRD results show that CeO2 in Ti/SnO2+Sb2O3/SnO2+CeO2 displayed a good crystal structure, and there was no significant oxygen evolution reaction occurred after electrolytic oxidation. Compared with the other three electrodes, the Ce-doped …
Naio4 Oxidation Of Mussel Adhesive Protein Film And Its Corrosion Protection For Mg-1.0ca Alloy, Rui-Qing Hou, Ping-Li Jiang, Shi-Gang Dong, Chang-Jian Lin
Naio4 Oxidation Of Mussel Adhesive Protein Film And Its Corrosion Protection For Mg-1.0ca Alloy, Rui-Qing Hou, Ping-Li Jiang, Shi-Gang Dong, Chang-Jian Lin
Journal of Electrochemistry
The effect of oxidation of mussel adhesive protein (Mefp-1) film on the corrosive resistance for Mg-1.0Ca alloy was investigated by scanning electron microscopy (SEM), atom force microscopy (AFM), electron probe microanalysis (EPMA), Infrared reflection absorption spectroscopy (IRAS) and electrochemical methods. The results showed that the NaIO4 induced oxidation of the pre-formed Mefp-1 film with porous morphology involved structural change of the DOPA group in the protein and resulted in a more uniform film with net-like morphology. The protein film without oxidation had an increasing resistance for the corrosion of Mg-1.0Ca alloy up to 7 days exposure. After oxidation, Epit …
