Liquefied petroleum gas (LPG) is extensively used in households and industries. It is a combustible gas and leakages can lead toexplosions. It is also toxic and exposure to it above a certain level can be fatal and as such real time monitoring and accidentalleakage detection is crucial. Metal oxide semiconductors are known for their gas sensing property. Spherical microstructures ofZnO, a wide band gap semiconductor, were synthesized following a simple hydrothermal route. Thin films of these microsphereswere used to detect LPG down to 1000 ppm by observing the change in electrical resistance. Platinum (Pt) nanoparticles weredeposited on the sensing mediurn as a catalyst to improve the performance of the sensors. Maximum response of 55.8% wasachieved for 5000 ppm ofLPG at 250oC.
