摘要

采用电化学方法制备了泡沫状Cu2O/Ag2O二元纳米异质结构。研究了它们的光电化学和光谱性质。研究了这些复合材料在水蒸气气相还原二氧化碳过程中的光催化性能。与Cu2O相比,在可见光照射下,二元纳米异质结构的形成导致甲烷产量增加,其他有机产物(乙醛、乙烯和乙醇)的数量增加。这种效应可以通过形成具有相互一致能量分布的纳米结构Cu2O/Ag2O二元复合材料来解释。

Photocatalytic Reduction of Co2 Under Visible Light with the Participation of Binary Cu2O/Ag2O Nanoheterostructures

Foam-like binary Cu2O/Ag2O nanoheterostructures have been obtained by an electrochemical method. Their photoelectrochemical and spectral properties have been studied. The photocatalytic properties of these composites in the process of gas-phase reduction of carbon dioxide with water vapor have been studied. The formation of binary nanoheterostructures leads to an increase in methane yield and an increase in the amount of other organic products (acetaldehyde, ethylene, and ethanol) while the system is irradiated with visible light when compared to Cu2O. This effect can be explained by the formation of a nanostructured Cu2O/Ag2O binary composite with a mutually consistent energy profile.
