Preparation of the cathode includes:shaping under the press of 40Mpa, sintering at 550℃for 1 hour and at 900℃for 8 hours and threading with molybdenum bar; Considering the literatures we choose CaCl2 as salt for preparation titanium. Pretreatment of salt is for 1 hour at 100℃and for 2 hours at 300℃. Partial pressure of oxygen which need lower than 5.11×10-7Pa to reduct titanium oxides and hygroscopic property of salt need a sealed equipment to electrolyse. And finally successfully designed a satisfied one and the results show that the equipment can be satisfied the requirment of the experiment. Flow of the inert gas is 1.5L/min, the voltage is 2.8 V, temperature is 850℃and time is 2 hours during pre-electrolysis. Flow of the inert gas is 0.2L/min, the voltage is 3.1 V, temperature is 900℃and time changes with the mass of TiO2 during electrolysis, namely the greater need the longer time; To eliminate influence of salt and other impurities, the products need to wash with distilled water and dilute chlorhydric acid , then wash with dilute hydrochloric acid under supersonic wave assistant. Finally, electrometical properties of the electrolysis of TiO2 is researched by cyclic voltammetry and chronoamperometry, and results show that there are two main reodox steps, namely from TiO2 to TiO and from TiO to Ti.
阴极制备主要包括40MPa压力下模压成型、两段式烧结(1小时内升至550℃保温1小时,再1小时升温至900℃保温8小时)及烧结后TiO2块打孔用钼棒串接三个主要环节;实验中选用CaCl2作为电解熔盐,并对其进行预处理(100℃,保温1小时; 300℃,保温2小时);经热力学计算,还原钛氧化物的氧分压至少要低于5.11×10-7Pa,结合电解过程中所用熔盐CaCl2有极强的吸水性的特点,电解装置应有较高的密封性,自行设计了一套密封性可靠的电解装置,便于实验过程中熔盐预处理和氧分压的控制;通过干燥处理预电解过程中Ar流量大约为1.5L/min、电压为2.8 V、温度为850℃、时间为2小时,电解过程中Ar流量大约为0.2L/min、电压为3.1V、温度为900℃,实验结果表明电解时间与TiO2质量密切相关,质量越大需要电解的时间越长;通过自来水冲洗—稀盐酸浸泡、洗涤—在超声波辅助作用下稀盐酸洗涤,可减少熔盐及其它杂质对电解产物检测结果的影响;最后,通过循环伏安法、计时电流法对电解机理的研究,确定电解还原TiO2制备金属钛主要经历了TiO2-TiO-Ti的过程。

Under the influence of the sunlight and with the help of its strong oxidization capacity, the photo-catalyst can oxidize nearly all the organic matters on the surface into H 2 O and the corresponding nontoxic inorganic materials. At the same time, under the combined actions of the characteristic nanometer structure of its surface, the hydroscopic properties of the complex additives and the light-induced amphiphilic properties (hydrophilicity and lipophilicity) of Ti02 itself the surface of the glass is made superhydrophilic, so that it becomes easily washable, anti-fog and not vulnerable to recontamination to keep the glass clean and transparent. And it also has such functions as sanitization, sterilization, foreign odor elimination and air refreshing.
