Gas Phase Synthesis of Nanoparticles of Interest in Electrochemical Devices

Abstract

In all fields related to energy transition (storage, catalysis…), the development of efficient materials is a key issue. Among synthesis methods of materials, gas phase techniques offer several advantages such as versatility, continuous production with good efficiency.
This presentation will illustrate the interest of one specific method: the laser pyrolysis method for the synthesis of oxide and non-oxide nanoparticles and composites (Si, SiC, Si@C, M-TiO2, CNT-TiO2…). Based on these materials, various applications can be developed in very different fields including mechanical, photocatalytic, photovoltaic properties… More details will be given on our recent work dealing with Si-based nanoparticles for electrochemical energy storage, tantalum oxynitride for electrocatalysis and Metal -titanium oxide for photocatalysis.


Biography

Prof. Herlin-Boime received her Ph.D. at University Paris sud in 1990 on investigating the growth mechanism of silicon carbide in a chemical vapor deposition reactor by using in situ Raman spectroscopy. In the same year, she joined the Atomic and Alternative Energy Commission (CEA) as a research scientist. During the past years she developed the laser pyrolysis method to improve its versatility towards i) various chemical composition including out of equilibrium phases, ii) push the limits of methods towards the synthesis of smaller nanoparticles (less than 10 nm diameter), iii) develop a two stages reactor for the one step synthesis of core@shell nanoparticles. Her interest mainly concerns the nanoparticles with applications in the field of energy and environmental sciences.
