Tuning properties of BImetallic supported catalysts with ultra-low NOble MEtal contents from solid to liquid state – BiNoMe

The BiNoMe project aims at developing new supported heterogeneous bimetallic catalysts with ultralow noble metal contents taking into account the possibility of forming bimetallic nanoparticles in the liquid or solid state during the reaction of propane dehydrogenation at high temperature, by playing on the melting temperature of the other metal component.
Bimetallic catalysts, prepared by surface redox reaction, will be characterized in depth at different stages of their life, not only after synthesis, but also during and after the catalytic reaction and the regeneration step. The combination of near operando transmission electron microscopy and theoretical modelling, taking into account the high temperature and the presence of reactive gases, will allow determining the interplay between surface structuration, state of the nanoparticles, catalytic properties and stability of the materials in the reaction conditions, opening the way to new formulations of highly performant catalysts.
This transdisciplinary project involves complementary academic research groups specialized in Chemistry (Heterogeneous catalysis), Physics (High resolution in situ TEM imaging and spectroscopy) and Theoretical modelling (DFT and multiscale simulation).
