| 摘 要：采用“靜電結合與水熱法”制備了二氧化鈦/氧化石墨烯（TiO2/GO）復合材料，并對該材料的光催化性能進(jìn)行了研究。以惡臭氣體中氨氣、硫化氫為代表性氣體，通過(guò)自制的反應裝置，研究了復合材料對它們的光催化性能，探究了GO摻雜比例、反應時(shí)間、紫外燈波長(cháng)等因素對光催化降解的影響。結果表明：在365 nm紫外燈照射下，GO摻雜量4%的TiO2/GO復合材料去除氨氣和硫化氫的效果最佳，去除率分別達96.01%和93.45%。 |

| Abstract：Titanium dioxide/graphene oxide (TiO2/GO) composites were prepared by “electrostatic bonding and hydrothermal method”, and their photocatalytic properties were studied. Taking ammonia (NH3) and hydrogen sulfide (H2S) in malodorous gas as the representative gases, the photocatalytic performance of the composites on them was studied through a self-made reaction device, and the effects of GO doping ratio, reaction time and wavelength of UV lamp on photocatalytic degradation were explored. The results showed that under the irradiation of 365 nm of UV lamp, the TiO2/GO composite with 4% GO doping had the best effect on the removal of NH3 and H2S, and the removal rate were 96.01% and 93.45%, respectively. |
