A novel gas sensor based on hybrid platinum nanobox/single walled carbon nanotube composites shows improved gas sensing response time and sensitivity towards chlorine detection at room temperature compared to sensors fabricated from pristine carbon nanotubes. The enhanced sensor response is attributed to the improvement of the gas adsorption and charge‐transfer efficiency with the incorporation of Pt nanoboxes.
