按照文献Low-temperature solution synthesis of the non-equilibrium ordered intermetallic compounds Au3Fe, Au3Co, and Au3Ni as nanocrystals做Au3Ni纳米合金,详细步骤是The synthesis was modified from a procedure published by Zhou
et al. 8 In a typical reaction, HAuCl 4 · 3H 2 O (10.0 mg), oleylamine
(50 μL), and the appropriate amount of Fe(acac) 3 , Co(acac) 2 , or
Ni(acac) 2 to yield a 3:1 molar ratio were added to 5 mL of octyl
ether and heated to 80 °C under Ar. Then, 0.7 mL of 2.81 M
n-butyllithium was added quickly via syringe to 10 mL of octyl
ether, also at 80 °C and under Ar. Finally, the 5-mL octyl ether
metal salt solution at 80 °C was added quickly via syringe. The
reaction mixture was heated to 250 °C, the heat was turned off,
and the sample was cooled to room temperature. The product was
isolated by adding 10 mL of ethanol, centrifuging at 13 krpm, then
extracting into the toluene layer of a toluene/water mixture.
药品的量是按照Au:Ni=3:1的量加的,但是做出来Ni的量不够,差不多是Au:Ni=9:1了,请问这个问题要怎么解决。我用的时间是2h,250度。
