Highly Sensitive and Selective SnO<sub>2</sub>-Gr Sensor Photoactivated for Detection of Low NO<sub>2</sub> Concentrations at Room Temperature

Highly Sensitive and Selective SnO<sub>2</sub>-Gr Sensor Photoactivated for Detection of Low NO<sub>2</sub> Concentrations at Room Temperature

Chemical nanosensors based on nanoparticles of tin dioxide and graphene-decorated tin dioxide were developed and characterized to detect low NO<sub>2</sub> concentrations. Sensitive layers were prepared by the drop casting method. SEM/EDX analyses have been used to investigate the surfac...
