Photocatalytic Degradation of Organic Pollutants in Aqueous Solution

这是一个教师早期职业项目，其研究部分涉及二氧化钛作为光氧化催化剂通过降解进行环境修复。本项目将研究二氧化钛催化光氧化过程中有机中间体的积累和衰变。许多小组为了目前的目的研究了二氧化钛，但通常的方法是研究最初的步骤，并假设随后的中间产物迅速矿化。将二氧化钛与稀释的有毒物质溶液一起使用（在现实世界中必须这样做）将使中间体在很大程度上自发衰变，只有在知道中间体的性质和浓度时，才能知道其生物后果。该项目将是使用这种方法的少数几个项目之一，也是唯一一个由合成化学家领导的项目。教育工作以使学生更积极地参与学习过程为中心。詹克斯博士将按照这项研究的思路开展本科生实验室实验。在这个项目中，中间体在一个可能的未来技术，催化光诱导分解有机环境污染物，将进行研究。该项目将提供资料，用以研究引入生物危害的可能性。本计划亦将强调以学生为中心的学习，并将本研究纳入本科实验教学。

This is a Faculty Early Career project, the research part of which deals with titanium dioxide as a photooxidation catalyst for environmental remediation by degradation. The project will study the organic intermediate buildup and decay during titanium dioxide catalyzed photooxidation. Many groups have studied titanium dioxide for the present purposes but the usual approach is to investigate the initial step and to assume that subsequent intermediates are rapidly mineralized. Use of titanium dioxide with dilute solutions of toxics (as in the real world one must) will leave intermediates largely to decay spontaneously and the biological consequences will only be known when the nature and concentrations of the intermediates are known. The project will be one of only a few, and the only led by a synthetic chemist, using this approach. The educational work centers on making students more active participants in the learning process. Dr. Jenks will develop undergraduate laboratory experiments along the lines of this research. In this project the intermediates in one possible future technology, catalyzed light-induced decomposition of organic environmental contaminants, will be studied. The project will provide information from which the possibility of introduction of biohazards will be studied. The project will also emphasize student-centered learning and the integration of this research into undergraduate laboratory teaching.
