| Abstract: | Using Co(NO 3) 2 and CO(NH 2) 2 as raw materials,the nanometer-sized Co 3O 4 was prepared by homogeneous precipitation method.The influences of reaction time,raw materials ratio,drying time and pH of solution on particle size were investigated.The optimum conditions are as following:the pH of system:5,reaction time:3 h, CO(NH 2) 2 /Co(NO 3) 2(mole):4,drying time:10 h.The product has an average diameter of 25 nm with good dispersive and sphere-shaped. |
