An easy two-step microwave assisted synthesis of SnO2/CNT hybrids

Author: Motshekga, SC ; Kesavan Pillai, Sreejarani ; Ray, SS ; Jalama, K ; Krause, RWM Date: Nov 2011 Tin oxide (SnO2) - decorated carbon nanotube (CNT) heterostructures were synthesized by microwave assisted wet impregnation method. CNTs of three different aspect ratios were compared. The hybrid samples were characterized by powder X-ray ... Read more
Field emission characteristics of SnO2/CNT composite prepared by microwave assisted wet impregnation

Author: Kesavan Pillai, Sreejarani ; Motshekga, SC ; Ray, SS ; Kennedy, J Date: 2012 SnO2/CNT composites were prepared by microwave assisted wet impregnation at 60 °C. The process was optimized by varying the microwave power and reaction time. Raman analysis showed the typical features of the rutile phase of as-synthesized ... Read more
Preparation and antibacterial activity of chitosan-based nanocomposites containing bentonite-supported silver and zinc oxide nanoparticles for water disinfection

Author: Motshekga, SC ; Ray, SS ; Onyango, MS ; Momba, MNB Date: Jul 2015 This study was conducted to develop novel chitosan nanocomposites and to optimize the minimum amount and contact time required to achieve complete inactivation of bacteria in water. Gram-negative Escherichia coli and Gram-positive Enterococcus ... Read more
Recent trends in the microwave-assisted synthesis of metal oxide nanoparticles supported on carbon nanotubes and their applications

Author: Motshekga, SC ; Kesavan Pillai, Sreejarani ; Ray, Suprakas S ; Jalama, K ; Krause, RWM Date: Jan 2012 The study of coating carbon nanotubes with metal/oxides nanoparticles is now becoming a promising and challenging area of research. To optimize the use of carbon nanotubes in various applications, it is necessary to attach functional groups ... Read more
