A detailed understanding of catalyst surface and interfacial phenomena is essential to the rational design of more efficient energy conversion systems. In this talk, I will demonstrate how liquid-phase transmission electron microscopy (TEM) affords valuable insight into the complex organic/inorganic and solid/liquid/gas interfaces that govern catalytic behavior.
I will first review recent advances in confined TEM microcell design, before briefly discussing their application in real-time imaging of copper catalysts during the CO₂ reduction reaction (CO₂RR) [1]. I will then extensively cover how electrochemical liquid-phase TEM, applied to cobalt-based oxygen-evolving oxides, elucidates the effects of electrowetting and the active Co²⁺/Co³⁺ redox transition as the catalyst surface becomes increasingly hydrophilic [2]. Finally, I will present recent findings on iridium oxide-based catalysts, integrating experimental observations with molecular dynamics simulations and density functional theory calculations.
These advanced electron microscopy diagnostics offer fundamental insights into the 'true' starting state of catalytic systems and their evolution during electrocatalytic processes at a scale that is otherwise inaccessible, providing a powerful complement to other characterisation techniques.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
