Autor: Kaido Tammeveski, Arunachala Mada Kannan, Petri Kanninen, Sander Ratso, Ivar Kruusenberg, Tanja Kallio, Merilin Vikkisk

Publikováno v: Journal of Power Sources. 281:94-102

Direct methanol fuel cells are assembled and evaluated using Fumatech FAA3 alkaline anion exchange membrane. Two novel metal-free cathode catalysts are synthesised, investigated and compared with the commercial Pt-based catalyst. In this work nitroge

Enhanced electrocatalytic activity of nitrogen-doped multi-walled carbon nanotubes towards the oxygen reduction reaction in alkaline media

Autor: Ivar Kruusenberg, Sander Ratso, Merilin Vikkisk, Kaido Tammeveski, Urmas Joost, Ilmar Kink, Eugene Shulga, Protima Rauwel

Publikováno v: RSC Advances. 5:59495-59505

In this work multi-walled carbon-nanotubes (MWCNTs) were doped with nitrogen using cyanamide (CM) or dicyandiamide (DCDA). To incorporate nitrogen into the CNT structure, high-temperature pyrolysis in an inert atmosphere was performed. For surface ch

Electrocatalysis of oxygen reduction on nitrogen-containing multi-walled carbon nanotube modified glassy carbon electrodes

Autor: Ivar Kruusenberg, Eugene Shulga, Merilin Vikkisk, Kaido Tammeveski, Urmas Joost

Publikováno v: Electrochimica Acta. 87:709-716

The electrochemical reduction of oxygen was studied on nitrogen-doped multi-walled carbon nanotube (NCNT) modified glassy carbon (GC) electrodes employing the rotating disk electrode (RDE) method. Nitrogen doping was achieved by simple pyrolysis of t
