An organometallic compound is the key intermediate during the formation of colloidal Pt particles from [Pt(acac) 2 ] and Al(CH 3 ) 3 . Additional studies confirm the formation of stable Pt colloids with an average diameter of 1.2 nm, which are stabilized by organoaluminum components (see scheme). Without the stabilizer a Pt nanopowder with a particle size of 1.4 nm is isolated.
