The Influence of Top Layer on ZnO/Cu₂S/ZnO Films in Optoelectric and Photocatalytic Performance

Abstract

In this paper, the ZnO/Cu2S/ZnO complex films were fabricated by Radio Frequency (RF) magnetron sputtering, and their transparent, conductive and photocatalytic properties have been investigated. The results show the properties of ZnO/Cu2S/ZnO complex films vary when the top layer ZnO thickness changes.

Engineering Charge Transfer Characteristics in Hierarchical Cu2S QDs @ ZnO Nanoneedles with p–n Heterojunctions: Towards Highly Efficient and Recyclable Photocatalysts

“…In the last decade, enormous efforts have been made to prepare different photocatalysts, for example Ag 3 PO 4 /ZnO [105,106], ZnO/CuO [107,108], ZnO@AgI [109,110], TiO 2 /g-C 3 N 4 [111], MoS 2 @Cu 2 S [112], and so on, for degrading various organic dyes, such as methyl orange (MO) [112,113,114], RhB [105,106,107,108,115], methylene blue (MB) [116,117], phenol [118], etc. It can be seen from Table 1 that even if the components constituting the heterojunction photocatalyst are the same, the photocatalytic degradation efficiency is not the same due to the different conditions in experimental, such as, the amount of catalyst, the type and concentration of organic dyes, and the source used in photocatalytic degradation experiments, the distance between the sample and the source, and the exposure time.…”
