Kinetic Enhancement of Toxic Organic Oxidation by Semiconductor Photocatalysis

本项目的目的是研究几种典型的水中有机污染物的光催化氧化，因为改变这一过程中使用的催化剂的性质会对它们产生影响。本研究项目选用的催化剂为二氧化钛。这种物质的催化性能将通过使其经历各种改变其表面特征的物理和化学过程来改变。导致该奖项的提案是在NSF项目公告中的条件下提交的，标题为：“研究启动奖”，NSF 88-99。该项目解决了从水溶液中去除相对少量的有机污染物的问题。最终目标是一种利用太阳能驱动氧化过程的水净化和废水中有机物去除的过程。研究成果可应用于水和废水处理工艺及系统的工程设计。

The objective of this project is to study the photocatalytic oxidation of several representative organic contaminants of water as they are affected by altering the properties of the catalyst used in this process. The catalyst selected for this research project is titanium dioxide. The catalytic properties of this substance will be altered by subjecting it to various physical and chemical processes that alter its surface characteristics. The proposal leading to this award was submitted under conditions in the NSF Program Announcement titled: "Research Initiation Awards," NSF 88-99. The project addresses the problem of removing relatively small concentrations of organic pollutants from aqueous solution. The ultimate goal is a process for decontamination of water and removal of organics from wastewater that utilizes solar energy to drive the oxidation process. Results of this project may be applied in engineering design of water and wastewater treatment processes and systems.
