论文摘要
制备CE-ETS-10，并详细研究了甲烷的光催化耦合的能力。 CE修饰增强了ETS-10在甲烷转化反应上的光催化性能，并且可以在可见光照射下进行甲烷转化率。为了研究对ETS-10的各种稀土修饰，将各种稀土元素引入了ETS-10分子筛，并研究了相对的光催化甲烷转化性能。应用各种特征来检查稀土的修饰行为。 SPS的结果表明，葡萄干修饰会诱导可见的光光波，这意味着强烈的电子孔分离，从而增强了光催化性能。对于电荷孔分离，电荷孔的分离是非传统的N-N异质结，在原子尺度上是高度定向且有效的。该机制显示出甲烷转化反应的显着增强。
Ce-ETS-10 was prepared and their ability on photocatalysis coupling of methane has been studied in detail. Ce modification enhanced the photocatalysis performance of ETS-10 on methane conversion reaction, and the methane conversion can be carried out under irradiation of visible light. To study the various rare earth modification to ETS-10, various rare earth elements were introduced to ETS-10 molecular sieve, and the relative photocatalytic methane conversion performance were studied. Various characterizations were applied to examine rare earth modification behavior. The SPS results show that the Cerium modification induce visible light photovoltage, which means the strong electron-hole separation which enhance the photocatalytic performance. The charge-hole separation is non-traditional n-n heterojunction for the charge-hole separation is highly oriented and efficient at atomic scale. This mechanism shows significant enhancement for methane conversion reaction.
