文摘

A novel porous Pd nanostructure has been synthesized in an aqueous solution using a soft micelle template from the interacting species of 1,3,5-trimethylbenzene with a surfactant of hexadecyltrimethylammonium bromide for highly sensitive electrochemical detection of hydrogen peroxide (H₂O₂). The porous Pd nanostructure has been applied for the dynamic detection of H₂O₂ with changing concentration through the H₂O₂ electro-reduction process. Remarkably, the low detection limit of 0.25 μM (signal/noise of 2.6), the long linear range from 0.25 to 900 μM (correlation coefficient R = 0.992), and the high sensitivity of 201 μA mM^–1 were achieved.
