Metal oxide/g-C3N4 nanocomposites chemiresistive gas sensors: A review on enhanced performance

Talanta Open, Journal Year: 2024, Volume and Issue: 9, P. 100290 - 100290

Published: Jan. 26, 2024

Metal-oxide-semiconductors (MOS) gas sensors are widely used for detecting and measuring the concentration of various gases in different applications. Changing electrical resistance when MOS surface reacts with a specific is basis operation sensor MOS. They offer versatility fabricating them suitable supervising energy efficiency, monitoring health safety, controlling hazardous emissions. However, traditional suffer from poor selectivity usually require high operating temperatures. To overcome these limitations, researchers have explored strategies such as doping, bimetallic/co-doping, composite structures conductive polymers 2D materials polyaniline (PANI), polymethyl methacrylate (PMMA), polyvinyl alcohol (PVA), reduced graphene oxide (rGO), graphitic carbon nitride (g-C3N4), graphene. Among materials, g-C3N4 stands out due to its distinct characteristics, including chemical stability, porosity structure, abundance, lack toxicity, numerous defects. The exfoliated structure defects provide active sites adsorbing atmospheric oxygen facilitating reactions molecules. This review introduces sensors, covering their fabrication methods measurements. It then attentions on properties g-C3N4, synthesis methods, potential composition highlights enhanced sensing performance achieved by MOS/g-C3N4 nanocomposites detect gases.
