| 最近在准备毕设，外文翻译都不会。求助万能的吧友翻译下面这3句话：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. |
