自从1972年日本学者Fujishima和Honda发现TiO2电极能光电分解水以来,TiO2因其具有合适的禁带宽度,耐光腐蚀、无毒害、稳定性好等优点,成为半导体光催化领域的重点研究对象。TiO2在自然界常见的物相有三种:金红石,锐钛
Since Japanese scientists Fujishima and Honda discovered that TiO2 electrode can decompose water by photoelectric in 1972, TiO2 has been the main research object in the field of semiconductor photocatalysis because of its advantages of suitable forbidden band width, corrosion resistance, no poison and good stability. There are three common phases of TiO2 in nature: rutile and anatase
