This paper describes the decoration of AuNPs on carbon nano-onions (CNO) followed by its fabrication onelectrode surface for the sensitive determination of environmental pollutant hydrazine (HZ). A greenultrasonication approach was employed to decorate the AuNPs on CNOs and it follows electroless deposition. HR-TEM results reveal that spherical 10 nm-sized AuNPs were well dispersed on 30 nm-sizedCNOs. The obtained 3.7 eV spin–orbit coupling in the XPS Au4f region suggests the successful decorationof Au(0) on CNO. The Au@CNO nanostructure was then directly attached on GC electrode surface by simpleimmersion and achieved through p–p stacking interaction and the resultant electrode exhibited highelectroactive surface area and lower resistivity when compared to the CNO fabricated electrode. TheAu@CNO electrode was utilized to determine HZ in effluent samples and delivered higher electrocatalyticactivity by showing lower onset potential than the bare and CNO fabricated electrodes. The increasedelectroactive area and high electronic conductivity of Au@CNO nanostructure are attributed to theoffered lowest detection limit of 12 109 M (S/N = 3) and larger sensitivity of 485.7 lA/mM cm2. The green and environmentally benign approached Au@CNO nanostructure leads to their successfulimplementation in the determination of HZ in effluent samples.
