中文摘要:
      采用溶剂热法在N,N-二甲基甲酰胺溶液中合成了SrCl2和Bi(NO3)3不同摩尔比例(分别为5%、10%、30%、50%、80%)与对苯二甲酸形成的含Sr2+和Bi3+杂化体. 并在紫外可见光照射下对其进行了罗丹明B降解活性的评价. 结果表明:催化剂在紫外可见光下光氧化活性很好,其中摩尔比例10% SrCl2掺杂的催化剂光降解活性优异. 高的光催化活性归结于催化剂在紫外区域对光有很好的吸收及光生电子和空穴能有效地分离. 双金属离子能协同调节有机杂化体的光催化活性.
英文摘要:
      Organic hybrids involving Sr2+ and Bi3+ were prepared by a facile solvothermal method using terephthtic acid and different molar ratios of SrCl2/Bi(NO3)3 at 5%10%30%,50% and 80% in N,N-dimethylformamide. Their degradation activities were evaluated under UV-visible light irradiation. The results indicated that these hybrids exhibit excellent UV-visible light degradation activities of rhodamine B. The hybrid with molar ratio of SrCl2/Bi(NO3)3 at 10% exhibits excellent degradation activities. This was ascribed to its good UV absorption and effective separation of photogenerated electrons and holes. Dual metal ions can synergistically tune the photocalytic activities of organic hybrids.
