摘要

Cobalt oxide and 5% ruthenium-doped cobalt oxide were successfully synthesized following the sol-gel scheme. Thereupon, structural, optical, morphological and elemental studies were conducted utilizing a multitude of characterization techniques, viz. X-ray diffraction technique, Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, scanning electron microscopy and energy-dispersive spectroscopy. The crystallite size of Co3O4 and Ru-Co3O4 nanostructures was calculated to be 25 and 27 nm, respectively. Further, the synthesized materials were used to investigate their LPG sensing properties. The response time for Co3O4 and Ru-doped Co3O4 was calculated to be 35 and 21 s, respectively. The calculated recovery time for Co3O4 was 66 s while for Ru-Co3O4 it was 50 s. Doping of Ru in Co3O4 resulted in increased sensitivity and lowering of the response time and recovery time which suggests that Ru-Co3O4 can prove to be a prominent material for LPG sensing.
