摘要
通过溶剂热法合成了具有Z型异质结结构的MOF-74-Mn/g-C_(3)N_(4)光催化剂。在可见光照射下,其对四环素的降解率(60 min)达到95%,分别为MOF-74-Mn和g-C_(3)N_(4)的2.4倍和1.8倍。结果表明,MOF-74-Mn/g-C_(3)N_(4)Z型异质结可有效地实现光生载流子的空间分离,抑制光生电子-空穴对的复合,加快载流子的传输,从而提升光催化降解性能。
A MOF-74-Mn/g-C_(3)N_(4)photocatalyst with a Z-scheme heterojunction structure was synthesized via a hydrothermal method.Under visible-light irradiation,the degradation rate of tetracycline reached 95%within 60 min,which was 2.4 times that of the pure MOF-74-Mn and 1.8 times that of the pure g-C_(3)N_(4).The results indicate that the MOF-74-Mn/g-C_(3)N_(4)Z-scheme heterojunction can effectively achieve the spatial separation of photogenerat-ed carriers,suppress the recombination of photogenerated electron-hole pairs,and accelerate the carrier,thus enhancing the photocatalytic degradation performance.
