I-11 – Functional metal oxide interfaces in efficient electrochemical energy conversion, biomass conversion and charge storage systems



Organizers: Pawel Kulesza (University of Warsaw), Nicolas Alonso-Vante (Université de Poitiers), R. John Errington (Newcastle University).

This symposium invites papers that address the fundamental and applied aspects of application of nanostructured metal oxides and oxide clusters as supports, carriers or active components of electrocatalytic systems for low-temperature fuel cells, (photo)electrochemical water splitting, reduction of carbon dioxide or effcieint pseudocapacitive or battery-type electrochemical charging-discharging.

Systems of noble metal nanoparticles supported onto high surface area metal oxides are of considerable interest to electrocatalysis and fuel cell research. For example, the problems related to beneficial interactions between the metal oxide supports and the metal centers or even with reactants, including the reaction intermediates could be topics of discussion and interest. Other important issues include such features as the oxide mixing, morphology, and stability toward chemical or electrochemical attack, the structure of the oxide – solution interface and the surface acid-base properties. Hydrous oxides can be permeable to protons and their presence could improve proton mobility during electrochemical charging and at the electrocatalytic interface. While being nonstoichiometric, certain mixed-valence oxides exhibit pseudo-metallic conductivity and possess ability to undergo fast redox transitions that are crucial in many electrochemical applications. Attention will also be paid to polyoxometallates and such their characteristics as very strong acidity and proton conductivity, in addition to undergoing fast, reversible, multi-electron electron transfers leading to the formation of highly conducting, mixed-valence (e.g. tungsten(VI,V) or molybdenum(VI,V) heteropoly blue) compounds. In addition, by changing their chemical composition the acid-base and redox behavior can be modified and adjusted to a desired level. Polyoxmetallates can act as attractive components of redox catalysts and charge storage systems. The role of the acid character of heteropolyacids and their salts in their catalytic efficacy and dynamics of charge propagation could also be the topic of extensive discussions.

Specific areas to be covered during symposium include (but not limited to) design of cathode and anode materials, new preparative and processing approaches, fabrication of advanced materials and electrode characterization including in-situ and ex-situ methods, electrochemical properties and performances, electrode-electrolyte interfacial chemistry, computational modeling, and mechanisms and dynamics of redox processes, electronic and ionic transport, structure and reactivity.
