文摘
- •
Gold nanoparticles decorated mesoporous silica microspheres (Au-MSM) are synthesized.
- •
Au-MSM electrocatalytically oxidizes hydrazine and reduces nitrobenzene.
- •
The kinetic parameters are determined using chronoamperometric studies.
- •
Hydrazine and nitrobenzene in real water samples are satisfactorily determined using GC/Au-MSM.
