MWCNT‐Organoimido Polyoxomolybdate Hybrid Material: Analytical Applications for Amperometric Sensing of Hydrogen Peroxide

Abstract: We report a hybrid material obtained by dispersing the polyoxometalate n‐[Bu4‐N]2[Mo6O18NC13H9] functionalized with 2‐aminofluorene (POMAF) and multi‐walled carbon nanotubes (MWCNTs) in 1,3‐dioxolane (MWCNT‐ POMAF). We demonstrate the peroxidase‐like activity of the hybrid material and its application for the amperometric quantification of hydrogen peroxide at −0.450 V previous drop‐coating at glassy carbon electrodes, with a linear range between 1.0 μM and 6.0 μM and a detection limit of 330 nM. The reproduci… Show more

“…Referente a POMs imobilizados, alguns exemplos de moléculas muito utilizadas nestes estudos são dióxido de carbono, bromato, perssulfato, nitrito e peróxido de hidrogênio [16]. Particularmente sobre o peróxido de hidrogênio, podem ser encontrados na literatura trabalhos onde a faixa de potencial para eletroredução do mesmo ocorreu aproximadamente entre -0,35 V a -0,80 V vs. Ag/ AgCl [17][18][19][20]. No entanto, um valor elevado de potencial significa que termodinamicamente uma maior energia é necessária para que o processo ocorra [21].…”
