将商品化的二氧化钛(TiO2)与以尿素为原料制备的石墨相氮化碳(g-C 3N 4)混合,通过超声旋蒸方法制备g-C 3N 4/TiO2复合光催化剂。通过考察复合光催化剂对模型染料罗丹明B的可见光降解脱色反应,得到了最佳复合质量配比条件,并探讨了反应机理,在此基础上研究其对典型纺织染料雅格素蓝BF-RR和阳离子红FBL的光催化降解性能。结果表明:复合光催化剂较单一 g-C 3N 4 和TiO2的光催化活性高,并且当g-C 3N 4和TiO2的质量比为5∶1时,在氙灯照射下,复合光催化剂可在3 h内将罗丹明B染料几乎完全降解脱色,降解率达到95%以上。复合光催化剂循环回收使用5次后对染料的降解率仍可达到70%以上,表明其具有较好的稳定性和可重复利用性。使用g-C 3N 4/TiO2复合光催化剂,典型纺织染料溶液在可见光照射4 h后均可显著降解脱色,有望在印染工业废水的光催化降解脱色处理中得到实际应用。

在当代青年社交图景中,断亲现象的出现映射了青年群体在情感独立与自我实现间寻求微妙平衡的拉扯。疏离与牵绊的交织中,青年试图割断“关系”去定位真实的自我。搭子社交的兴起,则显露了青年群体对于轻松交往与情感保护的渴求。青年在浅交往与真情感间划清界限,展现了另一种以“缘分”开始的浅社交。然而,断亲并不代表青年可以忽视和谐亲缘关系的力量,而搭子社交所带来的短效保鲜式体验也需理性看待。浅缘社会中,青年应辩证看待“缘分”与“关系”,树立正确的家庭观与交往观,以寻求真正坚韧的亲密关系。
