| 中文摘要: |
| 我们通过原位还原的方法将吸附在g-C3N4表面上Cu2+还原，制备出Cu2O/g-C3N4复合材料，并利用XRD、SEM、FT-IR、XPS等分析手段表征Cu2O/g-C3N4.表征结果显示：Cu元素主要以Cu2O的形式吸附在g-C3N4载体上.另外，还考察了Cu2O/g-C3N4在"一锅法"合成吲哚-2-甲酸乙酯的反应中的催化性能.结果表明：即使在较低的催化担载量和温和的反应条件下，Cu2O/g-C3N4仍能表现出良好的催化性能并获得44.1%的收率. |
| 英文摘要: |
| The Cu2O/g-C3N4 composite material was prepared by in situ reduction of Cu2+ absorbed on the surface defects of the g-C3N4, and characterized by XRD, SEM, FT-IR, and XPS. The XRD and XPS analysis revealed that Cu element was mostly doped in the g-C3N4 in the form of Cu2O. The g-C3N4 and Cu2O closely together can be described, according to all the characterization result. In addition, the obtained composite was employed as catalyst for one-pot three-step formation of indole-2-carboxylic esters, and achieved the middle yield (44.1%) under the low catalyst loading and mild condition. |
