摘要:
以钨酸钠和盐酸为原料,碳纳米管为载体,采用一步法将钨酸颗粒直接沉积在碳纳米管管壁上,形成钨酸-碳纳米管 (H2WO4-CNTs) 复合物.或采用二步法将钨酸沉淀与碳纳米管复合,形成H2WO4-CNTs复合物.之后,在氧气气氛下进行煅烧,生成了氧化钨粉末.经物理性能测试,2种方法制备的H2WO4-CNTs复合物中钨酸颗粒的平均粒径分别为10 nm和100 nm.氧化钨粉末的平均粒径分别为250 nm和2 μm,比表面积分别为36.53 m2/g和13.99 m2/g.采用紫外可见分光光度计测定了氧化钨的光催化性能,在11 W的日光灯照射下,当光照时间为30 min时,脱色率分别达到93.8 %和79.1 %.结果表明,一步法制备的氧化钨因具有更小的平均粒径和更大的比表面积,表现出更好的物理吸附性能和光催化性能.
