論文摘要翻譯 化學方面的論文
|
|
麻煩哪位幫我翻譯一下論文摘要，本人英語水平實在太差，拜托用點心，翻譯完之后馬上把分全給了： 摘要: 本文采用水熱法制備了ZnAl2O4/ZnO復合光催化劑，并與氧化石墨進行復合。采用SEM、 XRD等手段對所得的催化劑的顆粒形貌、結(jié)晶程度進行表征分析。在模擬太陽光照射下，以光催化降解水溶性甲基橙（MO）為探針對所制備的系列光催化劑進行活性評估。并考察了Zn/Al、Zn/PEG、pH值、水熱溫度、煅燒溫度、氧化石墨的量對光催化活性的影響。結(jié)果表明ZnAl2O4/ZnO復合光催化劑在Zn/Al=1∶1.5、Zn/PEG=10∶1、pH=9，水熱溫度為180℃、煅燒溫度在500℃時降解甲基橙的效果較好，60分鐘后對MO溶液的降解率為97.8%。 摘要： 本文采用水熱法制備CuAl2O4 光催化劑，采用SEM、 XRD等手段對所得 的催化劑的顆粒形貌、結(jié)晶程度進行表征分析。在模擬太陽光照射下，以光催化降解水溶性甲基橙（MO）為探針對所制備的系列光催化劑進行活性評估。在Cu/Al=1:2時，考察了煅燒溫度，pH值，水熱溫度對光催化活性的影響。結(jié)果表明CuAl2O4光催化劑在pH=8，煅燒溫度在600℃時降解甲基橙的效果最好，60分鐘后對MO溶液的降解率為97.79%。 再用CuAl2O4光催化劑分別復合氧化石墨、CuS、ZnS、PbS等，在模擬太陽光照射下，對其進行光催化產(chǎn)氫，結(jié)果表明：當CuAl2O4 與氧化石墨按100:2比例進行負載，得出的催化劑產(chǎn)氫活性最高。其產(chǎn)氫速率達到22.5ml/h。 [ Last edited by 歐陽環(huán)宇 on 2012-5-29 at 12:25 ] |

Abstract: This paper prepare a ZnAl2O4/ZnO of composite photocatalyst by hydrothermal method, and the oxidation of graphite composite. Means of SEM, XRD, particle morphology, crystallinity of the obtained catalysts were characterized. Under simulated sunlight irradiation, the photocatalytic degradation of methyl orange (MO) as a probe for activity assessment of a series of photocatalysts prepared. And investigated the Zn / Al, Zn / PEG, pH value, temperature of the hydrothermal calcination temperature, the amount of the photocatalytic activity of graphite oxide. The results show that the the ZnAl2O4/ZnO composite photocatalyst Zn / Al = 1:1.5, of Zn / PEG = 10:1, pH = 9, the hydrothermal temperature of 180 ° C, the calcination temperature at 500 ° C degradation of methyl orange is better the degradation of MO solution after 60 minutes was 97.8%. Abstract: Hydrothermal Synthesis CuAl2O4 photocatalyst, using SEM, XRD, and other means of income The catalyst particle morphology, degree of crystallinity were characterized. Under simulated sunlight irradiation, the photocatalytic degradation of methyl orange (MO) as a probe for activity assessment of a series of photocatalysts prepared. Investigated the calcination temperature, pH, and hydrothermal temperature on photocatalytic activity of Cu / Al = 1:2. The results show that the light CuAl2O4 catalyst at pH = 8, the calcination temperature at 600 ° C degradation of methyl orange the best, 60 minutes after the degradation of MO solution was 97.79%. Then CuAl2O4 light catalyst were composite oxide such as graphite, of CuS, ZnS, PbS, their photocatalytic hydrogen production under simulated sunlight |
