Mesoporous Au/ZnO was fabricated via sol gel method for electrochemical sensor.
The current vs. hydrazine concentration is linear over the range of 0.2–14.2xA0;μM.
The sensitivity and limit of detection were 0.873xA0;μAxA0;μM−xA0;1xA0;cm−xA0;2 and 0.242xA0;μM.
Au-ZnO sensor showed long-term stability and fast kinetic detection within 10xA0;s.
The amperometric of Au/ZnO exhibits a rapid increase in the hydrazine oxidation.
