“…This is the case of the study of Cu 3+ -Cu 2+ -Cu + transitions in the orthorhombic YBa 2 Cu 3 O 7-x phase [185] and manganese complexes entrapped into zeolites [186]. The relative quantification of the species in two different oxidation states can be performed based on voltammetric data, under several favourable conditions, from the measurement of different electrochemical parameters [149,187]. This possibility is illustrated by the estimate of the Fe(III)/Fe(II) ratio in ceramic materials [149], and the identification/quantification of different lead and tin species [188] in archaeological glazed materials and speciation of manganese in carbonates and marine sediments [189,190] have been also reported.…”

Speciation involves also isomer discrimination, as is the case of cis-and trans-Cr(CO) 2 (dpe) 2 and trans-[Cr(CO) 2 (dpe) 2 ] + complexes (dpe = Ph 2 PCH 2 CH 2 PDh 2 ) [191,192].…”

“…These have been applied to voltammetric data in order to discriminate between different species displaying more or less similar electrochemical responses. Peak potentials and peak currents from cyclic, differential pulse, and square-wave voltammetries are typically used for the purpose of identification, but other parameters characterizing the shape of the voltammetric curves (peak width, peak to half peak separation, onset potentials), including Tafel slopes and ordinates at the origin can be used [206,207], and peak current and/or peak area ratios [149,208]. Principal component [209] and cluster analysis [149,195] multivariate chemometric methods have been applied to SSEAC.…”

Solid state electroanalytical chemistry (SSEAC) deals with studies of the processes, materials, and methods specifically aimed to obtain analytical information (quantitative elemental composition, phase composition, structure information, and reactivity) on solid materials by means of electrochemical methods. The electrochemical characterization of solids is not only crucial for electrochemical applications of materials (e.g., in batteries, fuel cells, corrosion protection, electrochemical machining, etc.) but it lends itself also for providing analytical information on the structure and chemical and mineralogical composition of solid materials of all kinds such as metals and alloys, various films, conducting polymers, and materials used in nanotechnology. The present report concerns the relationships between molecular electrochemistry (i.e., solution electrochemistry) and solid state electrochemistry as applied to analysis. Special attention is focused on a critical evaluation of the different types of analytical information that are accessible by SSEAC.

“…To discriminate the oxidation state of a system containing a reversibly reducible/oxidizable electroactive species in two oxidation states, one can use the reported voltam- metric methods [59][60][61] requiring, in principle, linear diffusion control and electrochemical reversibility. The application of such methods to solid materials is, in principle, possible because of the close similarity between the CV responses for species in solution phase and for ion insertion solids when reversibility exists [62].…”

The voltammetry of nanoparticles and scanning electrochemical microscopy are applied to characterize praseodymium centers in tetragonal and monoclinic zirconias, doped with praseodymium ions (Pr x Zr 1−x O 2 ), prepared via sol-gel routes. Doped zirconia nanoparticles were synthesized by a sol-gel liquid-phase route and characterized by different techniques, including X-ray diffraction powder pattern, ultraviolet-visible diffuse reflectance spectroscopy, infrared spectroscopy, and transmission electron microscopy (TEM). Gels annealed at around 400°C yielded tetragonal Pr x Zr 1−x O 2 phases. The monoclinic forms of Pr-doped ZrO 2 were obtained by annealing at temperatures higher than 1,100°C. TEM micrographs proved that the size of the nanoparticles produced was dependent on their crystalline form, around 15 and 60 nm for tetragonal and monoclinic, respectively. The electrochemical study confirmed that a relatively high content of praseodymium cation was in the chemical state (IV), i.e., as Pr 4+ , in both zirconia host lattices. The catalytic and photocatalytic effects of Pr 4+ centers located in the monoclinic zirconia lattice on nitrite reduction and oxygen evolution reaction were studied.

The electrocatalytic effect exerted by hematite, a ubiquitous component of clay bodies, on the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) can be used to acquire information on archaeological ceramics. The solid-state voltammetric response of different hematite and ochre specimens, accompanied by SECM analysis in contact with 0.10 M HCl aqueous solution, is described. In air-saturated solutions, catalytic effects on the ORR and OER are accompanied by Fe(III)/Fe(II) and Fe(IV)/Fe(III) redox reactions. Such processes are conditioned by a variety of factors, the hydroxylation degree of the mineral surfaces being particularly influential, and exhibit significant variations upon heating the specimens between 300 and 900 °C. Voltammetric measurements carried out on a set of archaeological samples of Apulian red-figured pottery dated back within 5 th and 4 th centuries BCE permit to obtain sitecharacteristic voltammetric profiles.
