合成PtCu3
|
|
初次做合成材料，最近参照一篇文献合成介孔八面体的PtCu3（反应步骤特别简单 aqueous CuCl2 (20 × 10?3 m, 1 mL)solution and aqueous H2PtCl6 (20 × 10?3 m, 1 mL) solution were added into a solution containing KI (30 mg), guanidine carbonate (100 mg), PVP (150 mg), ethanolamine (0.7 mL), and water (3.65 mL). After 30 min of sonication, the mixed solution was hydrothermally treated in 20 mL Te?on-lined stainless steel autoclave at 170 °C for 8 h. After cooling down to room temperature, the products were precipitated via centrifugation, and washed with ethanol–water mixture），但反应之后溶液为澄清透明的蓝色，看到文献上PtCu（纳米线形状）合成出来是黑色，，并且离心不下来，这代表是不是没有合成出来?求各位大神指点一下 发自小木虫Android客户端 |
