Abstract: In this paper, a review on recent developments in materials and methodologies for metal oxide semiconductor liquefied petroleum gas sensors operating at room temperature is presented. The goal of this review is to identify various types of gas sensors, LPG sensing materials, preparation and fabrication methods, characterization to study on the properties of the materials and analysis on parameters at room temperature. The review also investigates advanced hybrid nanostructured materials, elemental modifications and doping processes to improve LPG sensor performance. Surface reactivity of the sensing material could be accelerated by the use of appropriate catalyst. The morphology of a material can be improved by various methods, including changing the synthesis conditions, adding additives to alter the material properties and functionality by modifying its size, shape, and structure at the nanoscale. This review also emphasizes the role of suitable dopants in changing bandgap of the materials.
