    Resum:
    This paper reports for the first time a gas-sensitive nanohybrid based on trinuclear molybdenum sulfido clusters ((Bu4N)(2)[Mo-3(mu(3)-S)(mu-S-2)(3)Cl-6] (Mo3S7)) supported on graphene flakes (Mo3S7@Graphene). The nanomaterial, once implemented in a chemoresistive device, changes its electrical resistivity when exposed, at room temperature (RT), to toxic and harmful gases, such as hydrogen (H-2), carbon dioxide (CO2), carbon monoxide (CO), and benzene. Particularly, the Mo3S7@Graphene hybrid shows an outstanding sensing performance toward CO2. Theoretical calculations provide a better understanding of the plausible gas sensing mechanisms. These findings open the door for a new generation of molybdenum sulfido cluster-based sensors in which electronic interrogation can be implemented, advancing toward the realization of highly sensitive gas sensing.
