Poor selectivity, slow response and long recovery times are the main bottlenecks that have emerged since the fabrication of the first graphene-based sensor, consequently limiting its application in the sensing field. To mitigate these drawbacks, the following research has turned to the decoration of the material with metal and metal oxide nanoparticles, thus demonstrating their ability to modulate the selectivity of the material and to improve the overall performance. Starting from these premises, we present different materials obtained by functionalizing graphene with ZnO, SnO2 and TiO2 metal oxide nanoparticles in comparison with pristine graphene.
