摘要
Electrocatalysis of the oxidation of formaldehyde on silver-palladium-modified carbon ionic liquid electrode (AgPd/CILE) was investigated in 0.1 M NaOH. The electrochemical performance of the AgPd/CILE was compared with those of Pd/CILE and Ag/CILE. Ag plays an important role in the catalytic performance of AgPd nanocatalyst and yields an excellent antifouling effect. Amperometric measurements showed that AgPd/CILE is a promising sensor for the detection of formaldehyde in the range of 10.0 mu M70.0 mM with a sensitivity of 240.6 mu A?mM-1?cm-2 and a detection limit of 2 mu M. The method is free from interference of methanol, ethanol and formic acid.
