Nanomaterials Webinar | 2D Materials: From Theory to Applications
Welcome from the Chairs
3rd Nanomaterials Webinar
2D Materials: From Theory to Applications
The aim of this webinar is to bring together scientists, researchers and companies to attend and share their visions, experiences and recent research developments in the field of 2D materials.
The theme of webinar is “2D materials: from theory to applications”.
The webinar will provide an interdisciplinary platform to discus and debate the most recent theoretical and experimental works in the field of 2D materials.
2 topics will be extensively debated: (i) Electrosynthesis from exfoliated two-dimensional transition metal dichalcogenides and (ii) Ab initio 2D material design for sustainable applications.
Electrosynthesis from exfoliated two-dimensional transition metal dichalcogenides
Two dimensional (2D) materials have emerged as platforms for the study of heterogeneous catalysis. Thanks to their reduced dimensionality, their properties can largely be adjusted by modifying the elemental composition, the structural phase and the concentration of atomic vacancies1. Besides, 2D materials have also shown promise as single atoms supports used as catalytic active sites for key reactions including the production of hydrogen, the conversion of CO2 and more recently the nitrogen fixation2. Our research aims to develop strategies for designing nanosheets and to explore their catalytic behavior by combining both in-situ and operando investigations. Through several examples, I will review our practical approaches for engineering exfoliated 2D materials via the phase control, the defect concentration or via the inclusion of individual metal.

Ab initio 2d material design for sustainable applications
The evolution of technologies for environmentally friendly applications is deeply intertwined with research activities on material exploration and design, both in the laboratory and in silico. I will present key examples in which atomistic simulations proved fruitful in explaining and predicting properties of 2d materials for sustainable technologies. Density Functional Theory and many-body perturbation theory were successfully applied to hot fields such as electrocatalysis, with the development of new 2d carbon-based single atom catalysts, photocatalysis, by studying the exciton lifetimes of graphitic carbon nitride, photovoltaics, with the proposal of new ultrathin heterostructures based on transition metal dichalcogenides and, eventually, water treatment, by expanding the studies on porous graphene membranes. From all these examples, it will emerge how theoretical methods can provide valuable results to better interpret and guide the experimental activity.

Chair
Dr. Mikhael Bechelany (born in March 1979) obtained his Ph.D. in Materials Chemistry from the University of Lyon (France) in 2006. His Ph.D. work was devoted to the synthesis and characterization of silicon- and boron-based 1D nanostructures (nanotubes, nanowires and nanocables). Then, he worked as a post-doc at EMPA (Switzerland). His research included the fabrication of nanomaterials (nanoparticles and nanowires), their organization and their nanomanipulation for applications in different fields such as photovoltaic, robotic, chemical and bio-sensing. In 2010, he became a scientist at CNRS. His current research interests at the Institut Européen des Membranes de Montpellier (the European Institute of Membranes (UMR CNRS 5635) in Montpellier (France) focus on novel synthesis methods for metals and ceramics nanomaterials such as atomic layer deposition (ALD), electrospinning and/or on nanostructuring using nanosphere lithography, graphene and graphene-like materials. His research efforts include the design of nanostructured membranes for health, environmental and renewable energy applications.
Invited Speakers
Dr. Damien Voiry graduated from the National School of Chemistry and Physics of Bordeaux (ENSCPB) and completed his thesis at the Paul Pascal Research Center (CRPP) of the University of Bordeaux in 2010. From 2011 to 2016, Damien was a postdoctoral associate in the group of Professor Manish Chhowalla from Rutgers University in the United States. His postdoctoral work focused on the modification of crystal structures of metal chalcogenide nanosheets for electrocatalysis and electronics. Since February 2016, he has been a CNRS staff scientist at the Institut Européen des Membranes de Montpellier (the European Institute of Membranes in Montpellier). His current research aims to explore the use of low dimensional materials for the fabrication multifunctional membranes for separation application as well as energy applications. After joining CNRS, he oriented his research on 2D materials towards energy conversion and nanofluidics. In 2018, Damien Voiry was awarded an ERC starting grant to investigate the electrocatalytic reduction of CO2 from 2D materials. In 2020, he was nominated at the Young Academy of Europe and received the CNRS Bronze Medal. As of June 2021, Damien Voiry has published 52 research articles in prestigious journals including Science, Nature Materials, and Nature Nanotechnology, for a total number of citations of over 13,500 and an h-factor of 34.
