Abstract:
CuO, Al 2 O 3 , Ag 2 O and La 2 O 3 doped on SnO 2 nanoparticles were successfully fabricated by a hydrothermal route at 200 ° C for 3 h. The morphology and composition were characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and energy dispersive x-ray analysis (EDX). The results showed that the particle size is 6–8 nm without other impurities. The influence of CuO with a concentration of 0.5–3wt%, which was doped on sol SnO 2 5wt% by hydrothermal and vibration technique, was discussed. In addition, the gas sensitivity experiment of samples to 1% LPG in the temperature range of 230–430 ° C indicated the improvement in sensitivity and response time. In particular, the SnO 2 sol suspension 5wt% doped with CuO 2wt% showed the best sensitivity at 330 ° C .
