Mesoporous Pd/ZnO was synthesized via sol-gel with small particle sizes ∼ 2–5 nm.
The electrochemical detection of ethanol in aqueous solutions was conducted.
The sensitivity was found to be 33.08 μAcm−2 mM−1 with a limit of detection 19.2 μM.
The kinetics study revealed a mixed surface and diffusion-controlled processes.
