Reduced Graphene oxide/ZnO nanoflowers (rGO/ZnO‐NFs) composite has been synthesized in‐situ using asymmetric Zn complex (1) as a single‐source molecular precursor (SSMP) with GO at 150 °C. The rGO/ZnO‐NFs composite was characterized by PXRD, UV‐vis, SEM, EDX mapping, TEM and SAED pattern to confirm its purity and morphology. The rGO/ZnO‐NFs composite shows uniform distribution of nanoflowers on graphene sheets. The modified glassy carbon electrode (GCE) was fabricated by drop wise layering of the rGO/ZnO‐NFs composite at the surface of the GCE without using binder. The binder free modified electrode (GCE‐rGO/ZnO) was explored for detection of nitroaromatics such as p‐nitro‐phenol (p‐NP), 2,4‐dinitrophenol (2,4‐DNP), 2,4‐dinitrotoluene (2,4‐DNT) and 2,4,6‐trinitrophenol (2,4,6‐TNP). The fabricated sensor showed remarkable response for the both toxicants and explosives. The LOD, sensitivity and linear range for the studied toxicants and explosives were found to be in a good range: p‐NP=0.93 μM, 240 μA mM⁻¹ cm⁻² and 0.2–0.9 mM; 2,4‐DNP=6.2 μM, 203 μA mM⁻¹ cm⁻² and 0.1–0.9 mM; 2,4‐DNT=10 μM, 371 μA mM⁻¹ cm⁻² and 0.2–0.9 mM; 2,4,6‐TNP=16 μM, 514 μA mM⁻¹ cm⁻² and 0.2–0.9 mM, respectively.
