| 最近在準(zhǔn)備畢設(shè),外文翻譯都不會(huì)。求助萬能的吧友翻譯下面這3句話:Among various metal oxides being targeted for hierarchical pore design, titania thin films are promising multifunctional materials due to their high photoactivity and redox activity in applications including water purification, photovoltaic cells, and gas sensors.All of these applications employ the photoelectrochemical properties of titania, but the efficiency in these types of processes is limited by the rate of electron/hole pair generation at the active surface of the titania and by possible recombination of these charge carriers.In addition to doping with other transition metals or anions to tune the band gap, the photovoltaic performance of titania can be improved by the introduction of a mesoporous structure to provide abundant pores and large surface area. |

| 在針對(duì)分級(jí)孔設(shè)計(jì)的各種金屬氧化物中,二氧化鈦薄膜是具有前途的多功能材料,由于其有高光催化活性和高氧化還原活性,二氧化鈦薄膜廣泛應(yīng)用于水凈化、光伏電池、氣體傳感器,所有這些應(yīng)用都用到二氧化鈦的光電化學(xué)性質(zhì),但在這些應(yīng)用類型過程的光電效率受制于電子-空穴對(duì)在二氧化鈦的活性表面產(chǎn)生的速度、受制于光生載流子的復(fù)合幾率。除了摻雜其它過渡金屬或陰離子來調(diào)整帶隙外,也可引入一個(gè)孔結(jié)構(gòu)以提供大量的孔隙、擴(kuò)大表面積,來提升二氧化鈦的光電性能。 |
