摘要
首次报道了在丁醇及氢氧化钠条件下 ,采用微波热分解法加热分解乙酸钯制备了金属钯纳米颗粒 ,并用TEM、XPS对其进行了表征 .结果表明 :随着乙酸钯浓度的增加 ,金属钯纳米颗粒的平均粒径由 30 nm增至 5 0 nm.讨论了当乙酸钯浓度为 0 .5× 1 0 - 3mol/ L 时 。
Solvent stabilized Pd colloidal nanoparticles were prepared by a microwave thermal decomposition of palladium acetate in the environment of alkali and butyl alcohol . They were characterized by TEM and XPS. Their average particle diameters increase from 30 to 50 nm with increase in the concentration of palladium acetate. We also discussed the influence of the concentration of alkali on the particle size when the concentration of palladium acetate was 0.5×10 -3 mol/L.
