纳米CuO/Bi2O3粉体的制备及催化性能
Preparation and Catalytic Activity of CuO/Bi2O3 Nano-particles
【摘要】 以Cu(NO3)2,Bi(NO3)3和CO(NH2)2为原料,用水解法并掺加添加剂直接制备出纳米CuO/Bi2O3粉体。用FIIR,XRD和TEM对其组成、粒子大小、表面形貌进行表征。结果表明,CuO/Bi2O3为类球形纳米粉体,粒度均匀,粒径20nm~40nm。实验结果证明CuO/Bi2O3对合成丁炔二醇具有良好的催化活性和选择性。
【Abstract】 CuO/Bi2O3 nano-particles were prepared by a new method of improved homogeneous precipitation and were characterized by FI-IR, XRD and TEM. The experamental results showed the grain size distribution of CuO/Bi2O3 nanoparticles was within a narrow range(20 nm~40 nm) and the CuO/Bi2O3 nano-particles exhibited a good catalytic activity for the systhesis of butynediol.
