Abstract: In the relentless pursuit of advancing electrochemical technologies, gaining a profound understanding of the intricate dynamics governing nano alloy catalysts during reduction reactions, such as the electrochemical CO2 reduction reaction (CO2RR) or oxygen reduction reaction (ORR), emerges as a pivotal endeavor. This presentation delves into a pioneering approach employing direct imaging techniques, specifically focused on copper-based/platinum-based alloys, utilizing in situ electrochemical transmission electron microscopy (TEM). The objective is to illuminate the evolving nanostructures of these catalysts in real-time under the dynamic conditions of electrochemical reduction reactions.
Through the application of this cutting-edge technique, we aim to unravel the intricate interplay between catalyst morphology and electrochemical performance. This comprehensive exploration provides crucial insights that extend beyond mere observation, offering a deeper understanding of the structural transformations occurring during dynamic electrochemical processes. The outcomes of this study are anticipated to offer valuable guidance for optimizing catalyst design strategies, ultimately leading to the enhancement of overall electrochemical performance and stability.
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.
