Synthesis of two-dimensional materials using liquid metal catalysts: Instrument development for in situ studies — •Amirmehdi Saedi¹, Marc de Voogd², Arthur Sjardin², Gertjan van Baarle², and Irene Groot¹ — ¹Catalysis and Surface Chemistry, Leiden Institute of Chemistry, Leiden University, The Netherlands — ²Leiden Probe Microscopy BV, Leiden, The Netherlands

Two-dimensional materials (2DMs), e.g. graphene, hold great promise for future applications in many technological areas. The current state-of-the-art synthesis method of these materials involves the dissociative adsorption of gas-phase precursors on a solid catalyst. This process is slow by nature, inefficient, and environmentally unfriendly. Using liquid metal catalysts (LMCats) instead of solid ones bears the prospect of a continuous production of 2DMs with unprecedented quality and production speed. The aims of this multinational collaborative project are to develop instrumentation capable of studying the ongoing chemical reactions on a LMCat, in situ investigations on its catalytic activity, and unraveling the growth mechanisms of 2DMs on surfaces of LMCats. Gaining this knowledge would be the key toward establishing the first efficient mass production method for 2DMs using this new technology. (Visit http://lmcat.eu/ for more info)
