Project Description

Due to the increase in atmospheric pollution, including various toxic gases, the effective detection of pollutants has become a crucial objective over the last years. Harmful and toxic gases are usually detected by gas sensors based on optical, acoustic, and metal oxide semiconductor (MOS) sensors. Among them, MOS sensors are in high demand for industrial sectors due to their low cost, wide temperature range operation capability, as well as effectivity in the detection of a variety of toxic gases. Furthermore, toxic gases are also a serious safety issue for energy storage systems. Achieving a high level of safety and reliability is especially important for lithium-ion batteries (LIB), which release various toxic substances during thermal dispersal resulting in a fire. Thus, this research targets the synthesize of a novel highly sensitive gas sensors based on MOS (ZnO, SnO2 and WO3) by the methods of successive ionic layer adsorption and reaction (SILAR) and electrospinning with doping transition metal to determine harmful and toxic gases in low concentration.
