A High-Performance Low-Temperature LPG Detection by MgFe2O4/BiVO4 Chemiresistive Sensor
Journal of materials science Materials in electronics(2020)
Abstract
Liquid petroleum gas (LPG) is an extensively used cooking fuel and autogas that is toxic, explosive in nature, and has a considerable effect on humans and environment. The present study reports the development of a highly sensitive chemiresistive sensor towards LPG operating at low temperatures. A two-step process of solution combustion and hydrothermal method has been adopted for the synthesis of MgFe2O4/BiVO4 nanocomposite. This work reports the synthesis of the novel nanocomposite; catalytic BiVO4 incorporated in the porous MgFe2O4 and its application for LPG sensing. X-ray diffraction, Fourier transform infrared spectroscopy, Field emission scanning electron microscopy, and energy dispersive X-ray spectroscopy were used to analyse the structural, morphological, and compositional studies of prepared nanomaterials. LPG detection was carried out from 50 to 500 ppm, and the sensor with 8:1 at% showed a peak response of 58%, with short response time 37 s and 42 s of recovery towards 500 ppm of LPG at low operating temperature of 50 °C. Besides, the fabricated low-cost sensor showed excellent selectivity and long-term stability towards LPG. Highly efficient LPG sensing device fabrication can be facilitated by this sensor.
