摘要
采用水热法制备了锶掺杂钨酸铋复合光催化剂。通过SEM、XRD、IR对制备的催化剂进行了表征,探究了复合光催化剂对废水中四环素的催化降解性能。结果表明:合成的锶掺杂钨酸铋复合催化剂的光催化效果优于单一催化剂,自然光照60 min,其催化降解四环素率达到66%。
The composite photocatalyst of Sr-doped bismuth tungstate was prepared by hydrothermal method and characterized by SEM,XRD and IR.The catalytic degradation performance for tetracycline was investigated.The experiment results showed that the photocatalytic activity of Sr-doped bismuth tungstate was better than that of a single catalyst,and the degradation rate of tetracycline reached 66%after 60 min in sunlight.
