(Invited) Interaction of Anions with Partially Oxidized Carbon Nanotubes and the Influence on the Performance of Polypyrrole-Carbon Nanotube Composite Electrodes (2018)
Presentation / Conference
Wei, C., Akinwolemiwa, B., Yu, L., Hu, D., Xia, L., & Chen, G. Z. (2018, September). (Invited) Interaction of Anions with Partially Oxidized Carbon Nanotubes and the Influence on the Performance of Polypyrrole-Carbon Nanotube Composite Electrodes. Presented at AiMES 2018 Meeting, Cancun, Mexico

Partial oxidation of carbon nanotubes (CNTs) in mixed HNO3 and H2SO4 is commonly used for the preparation of polymer-CNT composites. This procedure, however, emits toxic NOx fumes, making it difficult for commercial scale-up. Herein we report an envi...

Electro-deoxidation of solid chromium oxide in molten chloride salts (2005)
Presentation / Conference
Gordo, E., Chen, G. Z., & Fray, D. J. (2005, February). Electro-deoxidation of solid chromium oxide in molten chloride salts. Paper presented at TMS Annual Meeting 2005, San Francisco, California, U.S.A

Chromium is industrially produced by aluminothermic reduction of Cr 2O3 or electrodeposition from the aqueous NH 4Cr(SO4)2 solution. The former makes more a expensive product than an electrolytic method because the reductant, aluminium, is produced b...

The use of electro-deoxidation to reduce titanium dioxide and other metal oxides (2001)
Presentation / Conference
Fray, D. J., & Chen, G. Z. (2001, October). The use of electro-deoxidation to reduce titanium dioxide and other metal oxides. Paper presented at Proceedings of the Fourth International Conference on Materials Engineering for Resources

Titanium is usually extracted by the Kroll process in which titanium tetrachloride is reduced by magnesium to form titanium sponge and magnesium chloride. This is an expensive and time consuming process which makes titanium a very expensive metal. Al... Read More about The use of electro-deoxidation to reduce titanium dioxide and other metal oxides.
