麻烦哪位帮我翻译一下论文摘要，本人英语水平实在太差，拜托用点心，翻译完之后马上把分全给了： 摘要: 本文采用水热法制备了ZnAl2O4/ZnO复合光催化剂，并与氧化石墨进行复合。采用SEM、 XRD等手段对所得的催化剂的颗粒形貌、结晶程度进行表征分析。在模拟太阳光照射下，以光催化降解水溶性甲基橙（MO）为探针对所制备的系列光催化剂进行活性评估。并考察了Zn/Al、Zn/PEG、pH值、水热温度、煅烧温度、氧化石墨的量对光催化活性的影响。结果表明ZnAl2O4/ZnO复合光催化剂在Zn/Al=1∶1.5、Zn/PEG=10∶1、pH=9，水热温度为180℃、煅烧温度在500℃时降解甲基橙的效果较好，60分钟后对MO溶液的降解率为97.8%。 摘要： 本文采用水热法制备CuAl2O4 光催化剂，采用SEM、 XRD等手段对所得 的催化剂的颗粒形貌、结晶程度进行表征分析。在模拟太阳光照射下，以光催化降解水溶性甲基橙（MO）为探针对所制备的系列光催化剂进行活性评估。在Cu/Al=1:2时，考察了煅烧温度，pH值，水热温度对光催化活性的影响。结果表明CuAl2O4光催化剂在pH=8，煅烧温度在600℃时降解甲基橙的效果最好，60分钟后对MO溶液的降解率为97.79%。 再用CuAl2O4光催化剂分别复合氧化石墨、CuS、ZnS、PbS等，在模拟太阳光照射下，对其进行光催化产氢，结果表明：当CuAl2O4 与氧化石墨按100:2比例进行负载，得出的催化剂产氢活性最高。其产氢速率达到22.5ml/h。 [ Last edited by 欧阳环宇 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 |
