摘要

本研究报告介绍了氮掺杂 Ag/ZnO/MWCNT 纳米复合材料的性能，利用微波辅助水热法通过银（Ag）掺杂变化来调节带隙。该研究采用透射电子显微镜 (TEM)、傅立叶变换红外光谱 (FTIR)、光致发光 (PL)、场发射扫描电子显微镜 (FE-SEM)、紫外-可见-近红外分光光度法、X 射线衍射 (XRD) 和能量色散 X 射线光谱 (EDX)，对纳米复合材料的光学和结构特性进行了表征。值得注意的是，随着银含量的增加，带隙从 3.18 eV 变窄到 2.52 eV，使亚甲基蓝和刚果红染料的光催化降解率分别提高了 97% 和 89%。这些发现揭示了 Ag/ZnO/MWCNT 纳米复合材料在环境和光电应用方面的潜力。

Bandgap Optimization in N-Doped Ag-Enhanced ZnO-MWCNT Nanocomposites for Improved Absorption

The present work reports the performance of nitrogen-doped Ag/ZnO/MWCNT nanocomposites, leveraging a microwave-assisted hydrothermal approach to modulate the bandgap via silver (Ag) doping variations. Employing transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), photoluminescence (PL), field emission scanning electron microscopy (FE-SEM), UV-visible-NIR spectrophotometry, X-ray diffraction (XRD), and energy-dispersive X-ray spectroscopy (EDX), the study characterizes the nanocomposites’ optical and structural properties. Notably, the bandgap narrows from 3.18 to 2.52 eV with increasing Ag content, enhancing photocatalytic degradation of methylene blue and congo red dyes by up to 97 and 89%, respectively. These findings reveal the potential of Ag/ZnO/MWCNT nanocomposites in environmental and optoelectronic applications.
