Facile synthesis of Bi2ZnB2O7-MoS2 Nanocomposites for Photodetector and Photocatalytic Rhodamine B dye degradation Application.

In this research, the visible light active performance of Bi₂ZnB₂O₇ (BBZO) was significantly enhanced through the formation of a composite with few layer MoS₂. The resultant MoS₂@BBZO catalyst was employed in both photocatalysis and photodetector applications. Comprehensive structural and morphological analyses of the MoS₂@BBZO catalyst were conducted using X-ray diffraction (XRD), Raman spectroscopy, field-emission scanning electron microscopy (FE-SEM), and transmission electron microscopy (TEM). The estimated band gaps of BBZO and the composite were found to be 2.8 eV and 1.74 eV, respectively. Rhodamine B degradation studies demonstrated that the catalyst achieved 75% degradation within 30 minutes. Additionally, the photodetector application was investigated, revealing rapid photo-switching capabilities and an increased photocurrent.
