摘要：

Gadolinium (Gd-0) and uranium (U-0) nanoparticles are prepared via lithium naphthalenide ([LiNaph])-driven reduction in tetrahydrofuran (THF) using GdCl3 and UCl4, respectively, as low-cost starting materials. The as-prepared Gd-0 and U-0 suspensions are colloidally stable and contain metal nanoparticles with diameters of 2.5 +/- 0.7 nm (Gd-0) and 2.0 +/- 0.5 nm (U-0). Whereas THF suspensions are chemically stable under inert conditions (Ar and vacuum), nano-particulate powder samples show high reactivity in contact with, for example, oxygen, moisture, alcohols, or halogens. Such small and highly reactive Gd-0 and U-0 nanoparticles are first prepared via a dependable liquid-phase synthesis and stand as representatives for further nanosized lanthanides and actinides.
