微时代背景下高职院校图书馆社会服务创新实践探讨——以大连职业技术学院图书馆为例

采用光沉积-液相化学法调节电子流向，构建了直接Z型TiO₂/Ag/Ag₃PO_{(4 )}(TAAPO)光催化材料.通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射仪(XRD)、X射线光电子能谱(XPS)、紫外-可见漫反射光谱仪以及光致发光(PL)光谱仪等手段对其进行表征，并对其在可见光照射下催化降解环丙沙星(CIP)的性能进行了研究.结果表明，当水体pH为3.0,催化剂分散浓度为0.3 g/L,CIP的初始浓度为15 mg/L时，光催化降解体系能够取得最佳的去除效果.在该组条件下，光照120 min CIP的降解率约为99%,并且在经历4个循环后仍然保持了良好的降解效果.在光催化降解CIP的过程中，主要反应活性物种为超氧自由基(·O₂

On the Innovative Practice of Higher Vocational Colleges Libraries Service Facing the Community under the Micro-Era Background: Taking Dalian Vocational and Technology College Library as an Example

under the micro-era background, the higher vocational college library has the responsibility to actively carry out various types information services for the community, participate in the construction of local economic and social, provide intellectual support for building a scholarly society. Taking Dalian Vocational and Technology College Library as an example, this paper elaborates the social service meaning, principle and the path of social service innovation practice.
