Gold nanoparticle decorated graphene for efficient sensing of NO2 gas

We have devised a method to simultaneously reduce graphene oxide and gold metal ions onto the surface of graphene. The nanohybrid was in-turn used for efficient sensing of NO2 gas. The nanohybrid was characterized using X-ray diffractometry, field emission scanning electron microscopy (FESEM), UV–Vi...
