The study of application of nonlinear dynamics on green chemistry

该计划将研究几种有机试剂的氧化动力学和机理，这些有机试剂可用于（1）还原染料，（2）形成新型光化学振荡器，以及（3）制备修饰电极。照明和非照明系统将进行研究，以设计一个绿色的过程中，还原剂可以通过光还原再生。研究将从以下三个方向进行：（1）均相体系中的反应动力学和机理，（2）反应扩散介质中的图案形成，（3）修饰电极的构建。对于动力学测量，反应将通过与参比电极耦合的Pt或离子选择性电极进行。光谱法也将被用来跟踪和分析反应。国家的最先进的仪器，如NMR，HPLC和质谱将被用来确定和量化的反应产物，这反过来将为我们的建模提供指导。除了对染色工业和化学分析新绿色技术的发展产生长期影响外，一类新型光控化学振荡器的实现还将极大地促进扰动非线性时空动力学的研究，该学科最近因其在催化、生物学、信息处理等领域的潜在应用而引起越来越多的关注。

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.
