Examples
- First there are the inputs and requirements from three different segments of the process industry .
首先存在着供应问题和技术要求问题，它来自催化过程工业的三个不同部门。 - Various synthetic procedures , modification methods of mesoporous alumina and its application for acid catalysis are reviewed herein
本文综述了介孔氧化铝合成、改性研究的历史与现状，及在酸催化过程中的应用。 - Then light - induced - electrons were not only on conduction band but on the continuum band , mainly between 2 . 65 - 3 . 0ev . the electrons whose levels state was below o _ ( 2 ) / o _ ( 2 ) had not deoxidizing ability , it was the electrons whose level state was above 0 _ ( 2 ) / 0 _ ( 2 ) that contributed to the photocatalysis , this conclusion was also proved by experiments
理论上说明，位于02 / o2一能级之下的光生电子不具有还原能力，对光催化过程有贡献的电子主要为位于02 / o2一能级之上的电子，实验过程也说明， 02 / 02一能级之上电子占据状态较多时其光催化性能较好。 - In this research , nanosize tio2 were prepared by wet chemistry method . the effects of technical condition , ion doping and noble metal modification on crystal structure of ti02 , crystal size and its distribution , spectrum and photocatalytic activity were studied in order to prepare nanosize tio2 of high photocatalytic activity . effect factors such as temperature in photocatalytic process were also studied
本工作选用湿化学方法制备纳米tio _ 2光催化剂，研究制备工艺条件、离子掺杂和贵金属沉积等对纳米tio _ 2晶体类型、粒径大小及分布，光谱性质和光催活性的影响规律，以期研制出具有高光催化活性的纳米tio _ 2光催化剂；同时研究光催化过程中光催化环境温度等因素对光催化活性的影响规律。
