英文摘要Precise and real-time detection of hydrogen peroxide (H2O2) is particularly necessary in pharmaceutical, industrial, and military applications because of the strong oxidability of H2O2. Here, an electrocatalytic active film with Au nanoparticles (Au NPs) embedded in a metal-organic framework (UiO-66) film was in situ prepared on the surface of an electrode for H2O2 detection. The size of Au nanoparticles and electrochemical activity of the Au nanoparticles/UiO-66 film could be controlled by manipulating the electrodeposition conditions. Since Au NPs are encapsulated into the pores of the UiO-66 film prepared in situ on a conductive substrate, aggregation of Au nanoparticles could be largely avoided, which promotes the catalytic activity and electron transfer of electrode materials. Therefore, the optimized Au nanoparticles/UiO-66 film sample presented a remarkable electrochemical response toward detection of H2O2 with an extended linear range (0.2-23 mM), a low detection limit (0.045 S/N = 3), high sensitivity (329 mu A mM(-1) cm(-2)), and good stability. Furthermore, the as-prepared H2O2 sensor also displayed the advantages of excellent anti-interference performance owing to the size selectivity of the regular triangular opening channel of the UiO-66 film. Combining these advantages, the proposed sensor may open a pathway for high-performance electrochemical sensors and bioelectronics.
