Nitrogen-doped carbon nanotubes as a metal catalyst support

Author: Mabena, LF ; Ray, SS ; Mhlanga, SD ; Coville, NJ Date: May 2011 The science and technology of catalysis is of fundamental importance to a national economy. Today about 90% of all technical chemicals are manufactured by the use of catalysts. Nanoparticles of noble metals are extremely important materials ... Read more
Ruthenium supported on nitrogen-doped carbon nanotubes for the oxygen reduction reaction in alkaline

Author: Mabena, LF ; Modibedi, Remegia M ; Ray, Suprakas S ; Coville, NJ Date: Oct 2012 Nitrogen-doped carbon nanotubes (N-CNTs) prepared via thermal chemical vapor deposition (CVD), were used to support ruthenium (Ru) nanoparticles made using a microwave assisted reduction technique. The amount of Ru deposited on N-CNTs was ... Read more
Ruthenium supported on nitrogen-doped carbon nanotubes for the oxygen reduction reaction in alkaline electrolyte; Poster

Author: Mabena, LF ; Modibedi, Remegia M ; Ray, Suprakas S ; Coville, NJ Date: Jul 2012 The oxygen reduction reaction (ORR) at the cathode of fuel cells plays an important role in controlling the performance of a fuel cell but the poor kinetics of the ORR hinders this performance. Currently platinum-based metals are the best ... Read more
