Mechanistic Insights into the Aminolytic Decomposition of Mo(CO)₆ to Form MoC₁₋ₓ Nanoparticles
Brendan Ward-O'Brien, Allison Forsberg, Yizhen Chen, Noah Malmstadt, Majed S. Madani, and Richard L. Brutchey
First mechanistic insight into α-MoC₁₋ₓ nanoparticle formation by investigating the aminolytic decomposition of Mo(CO)₆ in oleylamine (OAm) and N,N-dimethyloctadecylamine (DODA). Ex situ FT-IR, XRD, and in situ synchrotron SAXS reveal stepwise carbonyl ligand substitution, conversion to an isolable amorphous intermediate, and reaction-controlled crystallization, highlighting the critical role of solvent-dependent precursor–ligand interactions in controlling decomposition temperature, kinetics, and final nanoparticle size.
