摘要
采用不同溶剂,通过溶剂热法可控合成了系列CdS/g-C_(3)N_(4)复合光催化剂,并采用XRD和SEM对其结构、形貌进行了表征。结果发现,溶剂效应对CdS/g-C_(3)N_(4)复合材料中CdS的晶型和形貌以及g-C_(3)N_(4)都有较大影响,进而影响其光催化活性。在模拟太阳光下,CdS/g-C_(3)N_(4)复合材料比纯g-C_(3)N_(4)以及CdS具有更高的催化降解MB活性,且相同反应条件下,CdS/g-C_(3)N_(4)-DMF对MB的降解率最高,150分钟内达到90.2%。
A series of CdS/g-C_(3)N_(4) composite photocatalysts were controllably synthesized by solvothermal method using different solvents,and their structures and morphologies were characterized by XRD and SEM.It was found that the solvent effect has a great influence on the crystal form and morphology of CdS and g-C_(3)N_(4) in CdS/g-C3N_(4) composites,and further affects its photocatalytic activity.Under the simulated sunlight,the CdS/g-C_(3)N_(4) composites exhibited higher photocatalytic degradation activity of MB than pure g-C_(3)N_(4) and CdS.Meanwhile,the CdS/g-C_(3)N_(4)-DMF showed the highest photocatalytic degradation activity of MB(90.2%within 150 min)under the same reaction conditions.
