This program will investigate the kinetics and mechanism of the oxidation of several organic reagents which can be employed to (1) reduce dyestuffs, (2) form novel photochemical oscillators, and (3) prepare modified electrodes. Both illuminated and non-illuminated systems will be studied in order to devise a green process in which the reducing agent can be re-generated through photoreduction. Research will be pursued from the following three directions: (1) Reaction dynamics and mechanism in homogeneous systems, (2) pattern formation in reaction-diffusion media, and (3) the construction of modified electrodes. For kinetic measurements, reactions will be followed by a Pt or an ion selective electrode, coupled with a reference electrode. Spectroscopic method will also be employed to follow and analyze the reaction. State-of-the-art instruments such as NMR, HPLC, and mass spectrometry will be employed to determine and quantify the reaction products, which will in turn provide guidance to our modeling. In addition to the long term impacts on the development of new green technology for dyeing industry and chemical analysis, the achievement of a new class of photo-controlled chemical oscillators will also greatly facilitate studies of perturbed nonlinear spatiotemporal dynamics, a subject which has recently attracted increasing attention due to its potential applications in catalysis, biology, information processing, etc.

该程序将研究几种有机试剂的氧化的动力学和机制，这些试剂可用于（1）减少染料，（2）形成新型的光化学振荡器，（3）制备修饰电极。为了设计一个绿色过程，可以研究发光和未刷新的系统，可以通过光摄影来重新生成还原剂。研究将从以下三个方向进行：（1）均质系统中的反应动态和机制，（2）反应扩散介质中的模式形成，以及（3）修饰电极的构造。对于动力学测量值，反应将在PT或离子选择性电极之后与参考电极结合。光谱法还将采用遵循和分析反应。 NMR，HPLC和质谱等最先进的工具将用于确定和量化反应产品，这反过来又将为我们的建模提供指导。除了对用于染色行业和化学分析的新绿色技术的长期影响外，成就新的照片控制的化学振荡器还将极大地促进对扰动非线性时空动态的研究，该主题最近由于其潜在的应用而引起了越来越多的主题，该主题引起了人们的越来越多的关注，其潜在的应用在催化，生物学，信息处理等上，因此
