摘要
纳米TiO_(2)光催化在降解水中的有机物、杀菌除藻等方面与其他技术相比具有催化效率高,可循环使用、无二次污染、费用低等优点。研究表明,锐钛矿TiO_(2)的{001}晶面有极高的化学活性,我们可以利用这种特殊的纳米结构来合成一种可以直接利用太阳光进行氧化的TiO_(2)光催化剂,取代传统的加药方式,有效地处理循环冷却水中的有机物、藻类和细菌,提高热交换效率,这将为未来的水处理带来巨大的潜力。
Compared with other technologies,nano-TiO_(2)photocatalysis has the advantages of high catalytic efficiency,recyclability,no secondary pollution,and low cost in degrading organic matter in water,sterilization and algae removal.The study shows that anatase TiO_(2)with{001}facets exposed has extremely high chemical activity,and we can use this special nanostructure to synthesize a TiO_(2)photocatalyst that can directly use sunlight for oxidation,replacing the traditional dosing method,effectively treating organic matter,algae and bacteria in the circulating cooling water,and improving the heat exchange efficiency,which will bring great potential for future water treatment.
