UV-assisted room temperature NO2 sensor using monolayer graphene decorated with SnO2 nanoparticles
Source abstract
Abstract
Abstract A NO2 sensor based on novel SnO2/graphene nanocomposite materials was proposed. Monolayer graphene was decorated with tin oxide via drop-casting and vacuum annealing, and the monolayer graphene was prepared using the chemical vapor deposition (CVD) method. The nanocomposites were characterized by Raman spectroscopy and a scanning electron microscope (SEM). The gas sensing capabilities of the SnO2/graphene nanocomposites for NO2 gas were investigated. Compared with the pure graphene sensor, the sensitivity of the SnO2/graphene sensor is higher and the recovery time is shorter. Moreover, the recovery time of the sensor is clearly further shortened using transient UV light irradiation. The SnO2/graphene sensor augmented with transient UV irradiation can achieve fast response/recovery with NO2. The sensor was demonstrated to have huge potential for real-time detection of NO2 at room temperature (25 °C).
