photocatalytic reaction meaning in English
光催化反应
Examples
- Photocatalytic reactions may take place under room temperature and atmospheric pressure ， so they can be applied into the area of new types of heating , ventilation and air condition
由于光催化反应在室温和常压下即可进行，因此可用于开发新型通风和空调系统。 - The photocatalytic degradation of titanium dioxide on pollutants was illustrated in detail and several important effects on photocatalytic reaction were also discussed
详细评述了二氧化钛纳米粒子对污染物的光催化降解作用，讨论了几个影响光催化反应的重要因素。 - This work introduces some of typical photocatalytic reactions , domestic and overseas development position of phocatalysis technologies , the principle of nano - tio _ 2 photocatalytic reactions , the influence of the structure and quality of nano - tio _ 2 and water vapor on photocatalytic reactions , usual preparation methods of photocatalysts such as gas phase and liquid phase methods and so on , as well as the carriers and methods of nano - tio _ 2 photocatalyst loading
本论文介绍了一些典型的光催化反应实例，光催化技术的国内外发展现状、纳米tio _ 2光催化反应的原理、 tio _ 2纳米粒子的结构与性质及水蒸气对光催化作用的影响，气相法、液相法等常用光催化剂的制备方法，纳米tio _ 2负载所用的载体及其在载体上的固定方法。 - It was still a technical problem on how to add the air to the reactor in so small pressure difference . in addition , the photocatalytic reaction efficiency was very low at the high speed . the reactor will be large , the price will be very high and the electricity will be enormously consumed during the photocatalytic - oxidation of h2s in the methane
主要原因是沼气中不含氧，使用时气体流速大，压差小，而用光催化氧化方法消除h _ 2s需要有相当量的氧参与，在压差很小的情况下，一次空气的加入存在技术困难；在高气体流速条件下，光催化效率低，若用光催化方法消除h _ 2s ，反应设备庞大，耗电量高，价格昂贵，农民难以负担。 - The type of photocatalytic reaction was first - degree reaction which was not very typical , and the reaction speed constants could be used to judge the efficiency of photocatalysis . the tio _ ( 2 ) films were prepared on glasses by magnetron sputtering . the influences on the tio _ ( 2 ) films properties of various o _ ( 2 ) partial pressure , various sputtering power , various heat treatment method and n was studied too
加入光催化剂tio _ 2粉末以后，光催化反应速率增幅较大，其过程可以认为是准一级反应，可以用一级反应速率常数来表征光催化效率，降解甲基橙和甲基蓝的反应速率常数分别为0 . 003min ~ ( - 1 )和0 . 35min ~ ( - 1 )左右。
