abstract = {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(AMD)n] with M = Fe(II), Co(II),
Pr(III), and
tris(2,2,6,6-tetramethyl-3,5-heptanedionato)europium,
Eu(dpm)3, in the presence of TRGO in the ionic liquid (IL)
1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]).
The crystalline phases of the metal fluorides synthesized in
[BMIm][BF4] were identified by powder X-ray diffraction
(PXRD) to be MF2 for M = Fe, Co and MF3 for M = Eu, Pr. The
diameters and size distributions of MFx@TRGO were from (6 ±
2) to (102 ± 41) nm. Energy-dispersive X-ray spectroscopy
(EDX) and X-ray photoelectron spectroscopy (XPS) were used
for further characterization of the MFx-NPs. Electrochemical
investigations of the FeF2-NPs@TRGO as cathode material for
lithium-ion batteries were evaluated by galvanostatic
charge/discharge profiles. The results indicate that the
FeF2-NPs@TRGO as cathode material can present a specific
capacity of 500 mAh/g at a current density of 50 mA/g,
including a significant interfacial charge storage
contribution. The obtained nanomaterials show a good rate
capacity as well (220 mAh/g and 130 mAh/g) at a current
density of 200 and 500 mA/g, respectively.},
