摘要
以三聚氰胺和三聚硫氰酸为前驱体,利用热聚合法自组装形成g-C_(3)N_(4)纳米管。采用XRD、SEM、BET等表征手段研究g-C_(3)N_(4)纳米管的结构和形貌,通过对盐酸四环素的降解考察g-C_(3)N_(4)纳米管的光催化活性。研究了不同前驱体质量比对g-C_(3)N_(4)纳米管结构及降解性能的影响。结果表明当三聚氰胺和三聚硫氰酸质量比1∶5时,所制备的g-C_(3)N_(4)纳米管比表面积最大,光催化活性最高,光照1 h可降解72.9%的四环素。
g-C_(3)N_(4) nanotubes were prepared via self-assembled thermal polymerization using melamine and trithiocyanuric acid as precursors.The structure and morphology of g-C_(3)N_(4) nanotubes were investigated by XRD,SEM and BET,and the photocatalytic activity of g-C_(3)N_(4) nanotubes was examined by the degradation of tetracycline hydrochloride.The effect of mass ratio of precursors on the structure and degradation performance of g-C_(3)N_(4) nanotubes was investigated.The results indicated that when the mass ratio of melamine and trithiocyanuric acid was 1∶5,the prepared g-C_(3)N_(4) nanotubes showed the largest specific surface area and the highest photocatalytic activity,and 72.9%of tetracycline could be degraded after illumination of 1 h.
