Electrochemistry and Electroactive Materials

Led by Prof. Nieves Casañ-Pastor

Summary: The use of electrochemical methods in the preparation of new materials and  the tuning of their properties by cation and anion doping in soft synthesis conditions.  ----- Applications in new concepts in energy storage, new mixed conducting phases, or electrostimulation of biological systems

The electrochemical doping, intercalation in mixed valence systems  and synthesis of oxides was initiated in the origin of the Department , led then by three researchers. Then, the specific line, supported up to three fourths of the Department budget thanks to National and European Grants, as well as Marato TV3 projects and industry contracts.

 

With a focus in mixed valence, mixed ionic-electronic conducting systems, the line has developed:

a) new solid state transformations and materials (AgCuO2)
b)  large changes in physical properties of materials by electrochemical reduction (polyoxometalates, vanadates), electrochemical oxygen intercalation (La2CuO4, LnCaMnO4,…), electrocatalysis in O2 evolution and CO2 reduction
c) electrodeposition (YBa2Cu3O7, IrOx, polypyrrole-PEDOT-X, hybrids IrOx-nanocarbons, Bi in Xray detectors)

d) use of electrochemistry in neural cell development
e) and bipolar electrochemistry effects inducing non contact electrochemistry and its application in energy storage and bioelectrochemistry effects.

Direct applications of those studies are found in 2D materials exfoliation, energy storage (supercapacitors with enhanced charge capacity, electrocatalysts in nanoform (POM) or coatings), and electroestimulation bioelectrodes. But also in fundamental aspects of the use of electrochemical processes to study the physicochemistry of materials.

DETAILS

1.- Intercalation processes that lead to notable changes in physical properties in bulk and thin layer forms lead to electrodes of various configurations that can be applied in tuning of materials properties, structure, energy storage, transport or in biological applications.

A big emphasis is made on the physicochemical parameters of such processes. Thus, Electrochemical Quartz Microbalance studies show the type and amount of species intercalated, material deposited or the mechanism of the actual reaction , a fundamental study that later allows to prepare hybrids based on organic-inorganic materials including conducting polymers, oxides or carbon nanostructures

Electrochemical Oxygen intercalation at room temperature

Open framework oxides allow intercalation processes that in some cases include oxygen ions if the mobility of them is possible. That is so in most of the copper oxides that are superconducting. The control of the oxygen stoichiometry makes possible a control of their physical properties. Even at room temperature, electrochemical methods allow induction of superconductivity or big changes in magnetism by doping. ECQM studies show that the actual insertion is a superoxide/peroxide type of oxygen, that if heated is transformed in oxide.

Electrochemical solid state transformations at room temperature

The same electrochemical treatment induces structure transformations in solid state at room temperature. Ej. Ag2Cu2O3 to Ag2Cu2O4 as shown below 1 O atom “intercalated” per unit formula. Pass from a 3D structure to a 2D one at r.t. !!!!; The final phase is a peculiar case where all elements are shown to be in mixed valence states.

Ag2CuMnO4 represents the first delafossite with Cu/Mn ordered with a 2D structure . Ferromagnetic coupling within the layers is coupled with Antiferromagnetic exchange among layers joined by Ag ions

Dalton Transactions, 2016, DOI: 10.1039/C6DT03986C
Oxidazing conditions render layered Silver-Copper oxides . In some cases are metallic, Ag2Cu2O4, in some others , ferromagnetic, Ag2CuMnO4 or Ag2Cu3Cr2O8(OH)4. In the last two cases, a significant difference lies on the connection among Cu-O layers. In one case direct bonding through Ag orbitals allows further antiferromagnetic coupling at lower temperatires, rendering a ferro-antiferrotransition. In the other Cu-O layers behave as completely isolated from each other.

Electrochemically exfoliated graphene in non -surfactant aqueous media

Electrochemical exfoliation of Graphite to yield Pristine Graphene

Anodic exfoliation in presence of surfactants or without them , has been possible from Carbon in the form of graphite. The pristine graphene obtained shows no defects as compared with the reduced graphene oxide, and has yielded a series of hybrid materials with a superior charge capacity useful in supercapacitors and electrostimulation electrodes

 2.- Electrochemical reduction of Polyoxometalates, nanoclusters of W and Mo , have allowed to elucidate the influence of delocalized electrons in the magnetic properties at the nanoscale. Such study  has been the base of the new studies of the role of POM as mediators in O2 evolution, and in M-O2 cells

3.- Electrodeposition methods

Reduction of metal precursors in presence of complexing agents, and further annealing has allowed the synthesis of YBa2Cu3O7 on Ag wires. As an alternative electrophoresis of suspensions of the preformed oxide also yields coatings of the oxide as shown in the figure. The opposite electrodeposition, Ag on the oxide , difficult for the rich redox chemistry of the oxide , is also possible in certain conditions

Interfase studies with neural systems and Electrostimulation

IrOx electrodeposited transparent coatings as the best substrates for neural growth in absence of electric fields and in presence of them when amorphous. Thermal evolution results in rutile structures. A channel spongy- like original oxohydroxide results: IrOx(OH)y.nH2O with a local rutile-like structure. Dynamic deposition has allowed a fourfould increase in charge capacity for this iridium oxide, and fully improved adhesion to the substrate

Neuronal scratch response to ELECTRIC FIELD DC applications. And neurotransmitters release under field effects using IrOx-Graphene nanostructured electrodes

 

Large charge capacity electrodes such as IrOx-graphene  allow DC electrostimulation without secondary effects due to radical formation. In that case, neurite extension is greatly enhanced above the effects of standard electrodes. Neurotransmitter release shows an enhancement in neural function under the electric field.  http://dx.doi.org/10.1016/j.apmt.2016.12.002
