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.

已经通过电化学方法获得了泡沫状二元Cu ₂ O/Ag _{2 O纳米异质结构。}已经研究了它们的光电化学和光谱特性。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 Cu 2} O相比，当系统用可见光照射时，二元纳米异质结构的形成导致甲烷产量增加和其他有机产物（乙醛、乙烯和乙醇）的量增加。这种效应可以解释通过形成具有相互一致的能量分布的纳米结构的Cu ₂ O/Ag _{2 O二元复合材料。}
