Enhancement the sensitivity of zinc sulfide nanostructure against NO2 toxic gas by loading graphene

الملخص EN

Nanocrystal-ZnS-loaded graphene was synthesized by a facile co-precipitation route.

The Graphene was affected on the characterization of ZnS which has been investigated.

XRD results reveal that ZnS has a cubic system while the hexagonal structure has been observed by loading graphene during preparation ZnS.

D.cconductivity proves that ZnS and ZnS/Gr have semiconductor behavior.

The sensing properties of ZnS/Gr against NO2 gas were investigated as a function of operating temperature and time under optimal condition.

The sensitivity, response time and recovery time were calculated with different operating temperatures (100, 150, 200)oC.
