Abstract

Tin oxide (SnO₂) - decorated carbon nariotube (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 diffraction, Raman spectroscopy, high resolution transmission electron microscopy, BET surface area analysis and DC conductivity measurement. The results showed that the microwave assisted synthesis is a very efficient method in producing CNTs that are heavily decorated by SnO₂ nanoparticles in a very short time (total reaction time of 10 min.), irrespective of their length and dameter. The hybrids showed 100 times increase in electrical conductivity when compared to the unmodified CNTs.
