The replacement of fossil-based synthesis of nitrogen-containing chemicals is essential for a
climate-neutral chemical sector. Conventional routes such as Haber–Bosch followed by downstream
transformations are highly energy-intensive and carbon-emitting [1]. Electrosynthesis
powered by renewable electricity represents a promising alternative, but electrocatalytic CN
coupling remains poorly understood, particularly with respect to reaction intermediates,
relevance of the catalyst surface structure, electrolyte effects, and mechanistic pathways.
Electrochemical C–N bond formation has recently been demonstrated as a viable route to
produce nitrogen-containing organic molecules, although current approaches still face low
yields, limited selectivity, and an incomplete mechanistic understanding [2]. Amino acids
represent an attractive class of target molecules due to their relevance as chemicals and
nutrients. In this work, alanine is used as a model system due to its structural simplicity and
its value as the smallest chiral amino acid, allowing broader insight into C–N electrosynthesis.
This study explores how catalyst properties and electrolyte conditions influence reaction
pathways and efficiency in electrochemical C–N coupling. By examining surface interactions,
intermediate formation, and competing processes, our objective is to develop general
principles that support the rational design of more selective and energy-efficient strategies
for the sustainable synthesis of coupled C-N molecules.
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.
