    摘要:

    采用空气氧化法制备了六角状氧化亚铜的镂空结构。在空气中氧气的辅助下,液相还原法制备的形貌、尺寸均一的六角状氧化亚铜(Cu2O)可被原位镂空成鱼骨状结构。采用扫描电镜(SEM)、X线衍射(XRD)、透射电子显微镜(TEM)、比表面积测试(BET)、紫外可见吸收(UVVis)光谱等手段对Cu2O材料进行形貌、结构及催化性能表征。结果表明,六角状Cu2O沿{100}和{111}面逐步向内腐蚀镂空,在空气辅助腐蚀2 h后,材料的比表面积相比镂空前增加了90%。光催化实验结果表明,镂空Cu2O材料的光催化性能提高了30%。

    Abstract:

    The hexagonal cuprous oxide (Cu2O) hollow structures were prepared by using the air oxidation method. With the aid of oxygen in the air, the hexagonal cuprous oxide (Cu2O) with uniform morphology and uniform size prepared by liquid phase reduction can be hollowed out in situ into a fishbone structure. The morphology, structure and catalytic properties of Cu2O material were characterization by SEM,XRD,TEM,BET and UVVis spectroscopy. The results show that the hexagonal Cu2O was gradually eroded inward along the {100} and {111} planes and the specific surface area of the material increased by 90% after 2 h of airassisted corrosion. The photocatalytic experiment results show that the photocatalytic performance of the hollow Cu2O material is increased by 30%.
