Synthesis of metal-fluoride nanoparticles supported on thermally reduced graphite oxide

Beilstein Journal of Nanotechnology, 2017
Metal-fluoride nanoparticles, (MFx-NPs) with M = Fe, Co, Pr, Eu, supported on different types of thermally reduced graphite oxide (TRGO) were obtained by microwave-assisted thermal decomposition of transition-metal amidinates, (M{MeC[N(iPr)]2}n) or [M ...
