Catalytic CO2 conversion to chemical feedstocks and carbon-based fuels powered by renewable energy sources constitutes a promising approach towards achieving a closed carbon cycle. Advancing this technology in the future relies strongly on optimization of the present catalytic systems to drive the conversion reaction with minimal energy losses and precise selectivity. In this respect, molecular catalytic centers as well as electrocatalytically-active 2D framework materials heterogenized onto suitable conductive support materials have emerged as interesting catalytic systems with prospective application potentials. The rational improvement such systems is based on the availability of in-depth information on the catalytic reaction mechanism that would allow for precise fine-tuning of the catalytic properties via chemical variations. To this end, particularly vibrational spectroelectrochemistry has established as a valuable tool to reveal and monitor the complex reactions. In contrast to other spectroscopic methods, this technique can be readily employed under in situ (aqueous) conditions and derives directly data on the catalytic steps at a molecular level.
This presentation discusses the versatility of (surface-enhanced) vibrational spectroelectrochemistry to study CO2 reduction catalysis specifically promoted by highly-active heterogenized molecular transition metal complexes and phthalocyanine-based 2D framework materials. The examples from the latest research include the application of operando IR absorption and confocal (resonance) Raman spectroscopy coupled to electrochemical control revealing crucial information on the reaction mechanism of the heterogenized catalysts with relevant implications on their afforded reactivity and selectivity.[1,2] The presentation concludes with an assessment of future prospects and novel experimental designs to increase the wealth of information that operando vibrational spectro-electrochemistry can derive.
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.
