Environmental and scalable synthesis of doped MOlybdenum (oxy)NItride or CArbide nanocomposites by laser pyrolysis for
electrochemical H2 or and O2 evolution reactions
MONICA is a multidisciplinary project focusing on the innovative, environmental and scalable synthesis of doped molybdenum (oxy)nitrides or carbides nanomaterials prepared by the Laser pyrolysis process. Achieving this new approach relies on the complementary expertise of the three academic partners (NIMBE, LINK and ISCR) and 1 industrial partner (Nanomakers). The final objective of this study is to evaluate the potential of a one-step reaction by Laser pyrolysis for the large production of doped molybdenum carbides or (oxy)nitrides, noted M:MoyXz/GC (M : Ni, Co, Cu, Fe; X = C, N). For environmental and industrial targets, two different Laser pyrolysis strategies will be used: (i) one using water solvent and commercial soluble molybdenum sources and (ii) another one based on an all solid process. Both strategies will use low-cost environmentally friendly precursors for Laser pyrolysis. In addition, the nanomaterials will be characterized finely and their electrocatalytic performances for water splitting reactions (hydrogen evolution reaction and oxygen evolution reaction) will be carefully studied as proof of concept, with the aim of applying the most promising materials as anode and cathode in an electrolyzer. In comparison to other works, we believe that our method is simpler, more efficient and quicker for preparing nanocomposite electrocatalysts. This project is based on preliminary results of the consortium on molybdenum carbide nanocomposites synthesized by Laser pyrolysis.
