A Novel Indoor Air Sensor Apply in Detecting Formaldehyde

As an indoor air toxic gas, formaldehyde is the main pollutant in interior decoration. In current work, we reported a novel formaldehyde gas sensing material and its gas sensing properties were investigated. We found that such novel two dimensional structure show excellent gas sensing performance towards formaldehyde and holding the potential of apply in detection of indoor air. Higher sensor response and faster response and recovery speed are primarily responsible for the unique morphology, leading to sufficient sensing reaction on the surface as well as abundant gas diffusion.
