摘要

在这项研究中，通过与少层 MoS₂形成复合材料，Bi₂ZnB₂O₇（BBZO）的可见光活性性能得到了显著提高。由此产生的 MoS₂@BBZO催化剂可用于光催化和光探测器应用。利用 X 射线衍射 (XRD)、拉曼光谱、场发射扫描电子显微镜 (FE-SEM) 和透射电子显微镜 (TEM) 对 MoS₂@BBZO 催化剂进行了全面的结构和形态分析。BBZO 和复合材料的估计带隙分别为 2.8 eV 和 1.74 eV。罗丹明 B 降解研究表明，催化剂在 30 分钟内实现了 75% 的降解。此外，还对光电探测器的应用进行了研究，结果表明这种催化剂具有快速的光开关能力和更大的光电流。

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.

期刊介绍： The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
