“…Several recent reviews cover salient features in diverse fields of applications about the SAM/Au [4 ± 6]. Cox and coworkers reported a phosphomolybdate (PMo 12 )/polyamidoamine dendrimer modified SAM/Au for arsenite oxidative detection [47]. Dendrimer is a branched polymer (Scheme 1) that has attracted significant attention over the last ten years and has been subjected to numerous reviews [48,49].…”

This review article updates recent developments in chemically modified electrodes (CMEs) towards analytical applications for the year of 2000 ± 2002 with 179 references. The broad topics are subdivided into four main categories: i) physisorption/chemisorption, ii) covalently linked, iii) homogenous (uniform) multilayer and iv) heterogeneous (non-uniform) multilayer CMEs. The criteria for the preparation of CMEs in elecrocatalytic systems are clearly described in Section 1. Some of the encouraging results related to Au-nanoparticles for DNA detection and new ceramic carbon, carbon nanotubes, copper-plated screen-printed and Nafion/lead ruthenate pyrochlore CMEs for catalytic application were especially discussed in this review.

“…Literature reports reveal that, in aqueous solutions, the oxidation and reduction overlapping processes existed in the potential interval from −0.2 to 0.8 V [15] and the capacitive-type behavior was postulated then. By contrast, the [15,[51][52][53], the redox reactions of the PMo 12 are interpreted in terms of three consecutive two electron processes and can be described as follows: . Under such conditions, the latter behavior is consistent with the surface-type behavior of the system.…”

A hybrid organic-inorganic material composed of poly (3,4-ethylenedioxythiophene), PEDOT, derivatized with 4-(pyrrol-e1-yl) benzoic acid, PyBA, and Keggin-type copper (II)-salt of H 3 PMo 12 O 40 has been proposed here. Such features as good electronic conductivity of PEDOT, hydrophilic and coordination capabilities of PyBA, the ability of copper ( I I ) i o n s t o l i n k P y B A c ar b ox y l i c g r o u p s , a n d phosphomolybdate anionic sites, as well as high protonic and mixed-valence conductivities of H 3 PMo 12 O 40 have been explored here to produce a stable composite material charcterized by reasonable charge propagation dynamics. Characterization and formation of the hybrid ca. 0.6 μm thick PEDOT/PyBA-Cu x H y PMo 12 O 40 films have been asessed by FTIR, XRD, AFM, SEM, as well as using electrochemical methods. Among important feautures of the proposed hybrid system is the ability to undergo reversible charging/ discharhging (both under voltammetric and galvanostatic conditions) in a manner analogous to what is observed in battery--type cells. Typical parameters, such as specific capacity, energy, and power densities, are provided and discussed.

“…Similar to CV behavior of GCE in 1 × 10 -3 molL -1 [PMo 12 O 40 ] 3-solution (pH = 2.0) or POM-GCE in the PBS solution (pH = 2.0), three well-defined reversible redox peaks (E 1/2 = -0.049, 0.179 and 0.324 V, respectively) can also be observed for POM@3DGF-GCE in pH = 2.0 PBS solution with only a slight change of E 1/2 (E 1/2 = -0.049, 0.179 and 0.337 V, respectively), which is ascribed to the strong ionic interaction or electron transfer interaction of POMs and graphene. Thus, it can be concluded that POMs have been successfully modified on the 3DGF[77][78][79][80].…”
