Low-Cost Sensors Based on Nanoparticles of Tin Dioxide Decorated with Graphene Used to Detect Ultra-Low NO<sub>2</sub> Concentrations at Room Temperature

Low-Cost Sensors Based on Nanoparticles of Tin Dioxide Decorated with Graphene Used to Detect Ultra-Low NO<sub>2</sub> Concentrations at Room Temperature

Chemical nanosensors based on nanoparticles (NPs) of pure tin dioxide (SnO<sub>2</sub>) and graphene-decorated tin dioxide were developed and characterized for the detection of pollutant gases. Sensitive layers were prepared by a drop casting method. The photoactivation of the sensors al...
