| 摘 要： | 研究不同温度下,并流和分步加料方式对葡萄糖还原法制备的氧化亚铜形貌及粒度的影响.结果表明:采用并流加料制备氧化亚铜,其粒度随温度升高而减小,而分步加料方式与之相反.采用NaOH和C6H12O6溶液并流加料方式下,所得氧化亚铜为晶粒直径10～30 nm的规则球形颗粒,反应温度对形貌影响不大,且粒度随温度升高而减小；而分步加料方式下,50℃所得氧化亚铜颗粒形貌为类球形;随温度升高逐渐转变为立方堆积体,但颗粒粒度却随温度升高而增大.

| Abstract: | The effects of temperature and feeding manners of reagents on the morphology and particle size of cuprous oxide prepared using glucose as a reductive agent were investigated.The results show that cuprous oxide particles prepared by feeding solutions of glucose and NaOH with parallel flow are spherical with a crystalline size of 10~30 nm,and the mean size of particles decreases with the increase of temperature.However,the morphology of cuprous oxide prepared by feeding solutions of glucose and NaOH with step flow transforms from spherical particle to cubic one with increasing temperature,the particle size increases with the increase of temperature. |
