Description
技术领域
本发明涉及水污染处理技术领域，具体为一种氮掺杂多孔碳负载花状Dy掺杂TiO2及在水污染处理中的应用。
背景技术
水污染主要是未经处理的生活污水、工业废水等随意排放进自然环境中，污染物主要有无机污染物和有机污染物，如Cu2+、Cd2+等重金属离子；亚甲基蓝、甲基橙等有机染料；四环素等抗生素等，目前对于污水处理和水污染治理的方法主要有物理絮凝法、化学吸附法、生物降解法、光催化降解法等。
吸附法是一种简单高效、成本低廉的水污染治理方法，吸附材料主要有活性炭、氧化铝、聚丙烯酰胺等，其中活性多孔碳材料具有孔隙丰富、比表面积高、结构稳定，重金属离子吸附和有机污染物吸附方面具有广泛的应用，纳米TiO2是一种常见的光催化剂，无毒无污染、制备方法简单、形貌可调控、光化学性能优异，在有机污染物降解方面具有重要的应用，因此可以采取提高纳米TiO2的光催化活性，增强活性多孔碳材料的吸附性能，同时将两者进行原位复合，得到具有吸附和光催化降解的双功能材料，应用于重金属离子和有机污染物的污水处理中。

(三)有益的技术效果
与现有技术相比，本发明具备以下有益技术效果：
该一种氮掺杂多孔碳负载花状Dy掺杂TiO2，通过调控氧化剂高碘酸钠的用量和反应条件，控制纤维的氧化度，得到醛基含量较少的低氧化度的纤维素，低氧化度的纤维素的开环度较少，碳骨架更加完整，成炭率高，容易被碳化。
该一种氮掺杂多孔碳负载花状Dy掺杂TiO2，纤维素分子链上的醛基与2,5-二氨基嘧啶的两个氨基发生席夫碱交联反应，得到嘧啶席夫碱交联纤维素，形成三维化学交联网络，三维空间结构使纤维素的比表面积更大，并且空间网络结构有利于碳化形成多孔碳结构，以纤维素三维碳骨架作为碳源，接枝的2,5-二氨基嘧啶作为氮源，通过碳化和氢氧化钾制孔作用，得到得到纤维素基氮掺杂多孔碳，并通过控制氧化度和醛基含量，来调节与和2,5-二氨基嘧啶的接枝率，从而控制多孔碳的含氮量，氮掺杂在碳层基体中形成丰富的含氮官能团，这些活性含氮官能团的氮原子上含有孤对电子，对Cu2+等重金属具有很强的螯合作用，起到对重金属离子的吸附效果，同时氮原子的电负性比碳大，具有高电负性，可以调节碳层表面的电荷排布，从而增强碳层的表面亲和性，促进对亚甲基蓝的吸附作用。
该一种氮掺杂多孔碳负载花状Dy掺杂TiO2，在醋酸的热溶剂体系中，以氮掺杂多孔碳作为生长载体，硝酸镝作为Dy源，通过热溶剂法，在氮掺杂多孔碳基体中原位生成花状Dy掺杂TiO2，原位生长法有利于花状Dy掺杂TiO2的分散性，改善团聚现象，同时花状的纳米TiO2具有更高的比表面积，同时Dy掺杂取代了部分Ti的晶格，产生的杂质能级有利于促进TiO2的光吸收边发生红移，使Dy掺杂TiO2在可见光下也具有良好的光吸收范围和光化学响应性，克服了传统的纳米TiO2只能在紫外光下进行吸收和光催化活性，使Dy掺杂TiO2具有优异的光催化降解活性，当氮掺杂多孔碳将亚甲基蓝吸附后，碳基体负载的Dy掺杂TiO2可以将亚甲基蓝充分降解为无毒的小分子，实现高效的光催化降解过程。
