0102983CrittendenThis proposal was received in response to NSE, NSF-0019. The goal of this project is to design and synthesize novel TiO2-based nanotube p-n junction photocatalysts. The principal investigators have combined the p-n junction principle and concepts of template preparation of nanomaterials toyield a new general route for preparing nanotube p-n junction photocatalysts. Through this process, they will further understand the nucleation and growth of very small diameter semiconductor nanotubes. The morphology of these TiO2 nanotubes will be analyzed. The photocatalytic activity will be evaluated by examining the destruction of representative organic pollutants in the gas phase. The proposed research is expected to improve the quantum efficiency for photocatalytic destruction of environmental pollutants by providing a basis for designing and constructing TiO2-based nanotube photocatalysts. An important feature of the multidisciplinary research team is the integration of research and education through broader academic and research training of students in fundamental materials science, environmental science, and related technological areas.

0102983Crittenden 此提案是针对 NSE、NSF-0019 收到的。 该项目的目标是设计和合成新型 TiO2 基纳米管 p-n 结光催化剂。 主要研究人员结合p-n结原理和纳米材料模板制备的概念，提出了制备纳米管p-n结光催化剂的新通用路线。 通过这个过程，他们将进一步了解极小直径半导体纳米管的成核和生长。将分析这些 TiO2 纳米管的形态。将通过检查气相中代表性有机污染物的破坏来评估光催化活性。该研究有望为设计和构建二氧化钛基纳米管光催化剂提供基础，从而提高光催化破坏环境污染物的量子效率。多学科研究团队的一个重要特点是通过对基础材料科学、环境科学和相关技术领域的学生进行更广泛的学术和研究培训，将研究和教育融为一体。
