资源简介：
A novel sandwich polyoxometalate
(POM) Na12[WCo3(H2O)2(CoW9O34)2] and poly(vinylimidazolium) cation
[PVIM+] in combination with nitrogen-doped carbon nanotubes
(NCNTs) was
developed for a highly selective and ultrasensitive detection of dopamine.
Conductively efficient heterogenization of Co5POM catalyst
by PVIM over NCNTs provides the synergy between PVIM–POM catalyst
and NCNTs as a conductive support which enhances the electron transport
at the electrode/electrolyte interface and eliminates the interference
of ascorbic acid (AA) at physiological pH (7.4). The novel PVIM–Co5POM/NCNT composite demonstrates a superior selectivity and
sensitivity with a lowest detection limit of 500 pM (0.0005 μM)
and a wide linear detection range of 0.0005–600 μM even
in the presence of higher concentration of AA (500 μM).
