| Abstract |
The Bi2O3/Bi2S3 composite was synthesized via an in-situ sonochemical reaction. The in-situ growth of Bi2S3 provides a good interaction with the Bi2O3 layer. The resulting Bi2O3/Bi2S3 composite showed enhanced photoelectrochemical (PEC) activity compared to those of the other Bi2S3 electrodes. These enhanced levels of activity mainly originate from two factors: (1) the enhanced charge separation of Bi2S3 on the Bi2O3 layer due to the CB and VB of Bi2O3 being more positive than those of Bi2S3, which are favorable for the charge separation of Bi2S3, and (2) the effective composite interface with less interfacial defects by the in-situ growth method. These findings provide important guidance for the design of highly efficient electrodes, particularly bearing on hetero-structures, for enhanced PEC performances. |
