These results indicated that a well structured anatase TiO2 was obtained by impregnation method under 500℃. Flow rate, in the activity test, could be neglected for mass transfer effects. As a matter of fact, relative humidity played the most important role in this reaction. The highest removal efficiency was obtained while relative humidify of 56.8%. Water molecules are sources of ; however, excessive water molecules could inhibit reactions by competing activity sites with organic containments. In the regeneration test, photocatalyst could be reactivated through a running water vapor with UV light illumination process.

研究结果指出，以含浸法制备之触媒於500℃锻烧下，具有良好的锐钛矿晶体结构；另外在活性测试的部份，流量的增加，污染物之去除效果不受影响，所以本实验选择以200ml/min之流量可忽略质传影响；湿度扮演重要的角色，当RH=56.8％时去除效率最高，主要因水气是产生氢氧自由基的主要来源，但是过多之水气可能与有机物竞争触媒表面上的活性位置，因而抑制反应的进行；初使浓度对去除率之影响中得知，初使浓度的高低不会影响触媒对有机物的催化能力，实验使用之触媒量适合催化200~250ppm之有机物，可藉由增加触媒量提高对有机物之催化能力；此外再生的测试，触媒可经由连续曝水及紫外光的照射，使触媒恢复原有的活性，可再次利用。

There are three platinum catalyst micro channels which have different width ,such as 1000 m , 400m and 40m. The platinum catalyst micro channel reactor is fabricated by MEMS technology. The reactor uses the exothermic reaction of hydrogen and oxygen on the platinum catalyst plate as the heat source and the platinum thin film resistance deposited on a glass chip by face micro machining process as catalyst and temperature sensor. The channel is bonded with a cover plate etched by bulk micromachining technology to become a mico- channel reactor.

Although many researchers have studied the synthesis of allyl phenyl ether by phase-transfer catalysis, no studies have used it in membrane reactor up to now. The purpose of this paper is to combine the studies of membrane reactor and phase-transfer catalysis. The membrane was used to stabilize the aqueous/organic interface at a fixed position, also the quaternary ammonium ion in the membrane was used as the catalyst to partake in the reaction system directly, and so it can also separate the product and reactants at the same time. A theoretical model is also presented.

中文摘要对於利用相间转移触媒催化技术来合成丙烯基苯基醚的反应，已有不少专家学者研究过，而至今还无在薄膜反应器中进行此反应之研究，本研究则是要结合薄膜反应器与相间转移触媒两者之特性，固定水油两相之界面，并且利用薄膜上的四级铵离子为触媒，直接在反应系统中参与反应，并同时分离产物及反应物，进而推导出相关之理论模型。

Different from Ni70Mn25Co5（suitable for growing （100）crystal plate）, Fe is suitable for growing (111) crystal plate. It may be related to that (100)growing area of Fe is very narrow. In diamond research with medium of Fe, most crystals are octahedron or six-eight body. It is very hard to synthesize hexahedron diamond.

与Ni70Mn25Co5触媒生长特性（适合于（100）晶面生长）不同，Fe作触媒适合于（111）晶面生长，这可能跟Fe触媒的（100）生长区非常窄有关，因为在Fe触媒粉末金刚石研究中，晶体基本为八面体或六八面体，很难合成六面体金刚石。
