摘要

采用水热法合成了0 - 8% Sr掺杂ZnO@g-C3N4的纳米复合材料，并对其进行了综合表征。研究通过x射线衍射（XRD）技术证实了ZnO@g-C3N4纳米复合材料的相纯度和Sr的成功掺杂。傅里叶变换红外光谱（FTIR）分析进一步支持了纳米复合材料中金属-氧键以及各种官能团的鉴定。场发射扫描电子显微镜（FESEM）成像显示了ZnO@g-C3N4纳米复合材料和Sr-ZnO@g-C3N4纳米复合材料的六角形纳米圆盘结构，透射电子显微镜（TEM）观察证实了这一发现。能量色散x射线光谱（EDAX）分析证实了合成的纳米复合材料的元素组成。采用紫外-可见光谱法研究了原始ZnO和Sr-ZnO@g-C3N4纳米复合材料的光学性质。随着Sr含量的增加（从0到5%），Sr掺杂ZnO的红移增强，证实了Sr掺杂水平的提高。而当Sr在ZnO中含量为7%和8%时，其吸收率降低，这是由于ZnO中Sr含量增加所致。x射线光电子能谱（XPS）提供了对元素氧化态的深入了解，特别是在5% Sr-ZnO@g-C3N4纳米复合材料中。对合成样品进行了光致发光（PL）光谱，以检测纳米复合材料内部的载流子动力学和缺陷状态。合成的Sr-ZnO@g-C3N4纳米复合材料可用于储能装置、环境修复和有机转化。

Tailoring structural and chemical properties of ZnO@ g-C3N4 nanocomposites through Sr doping: Insights from multi technique characterization

Nanocomposites comprising 0–8 % Sr doped ZnO@g-C₃N₄ were synthesized hydrothermally and comprehensively characterized. The study confirmed phase purity and successful Sr doping in ZnO@g-C₃N₄ nanocomposite through X-ray diffraction (XRD) technique. Fourier Transform Infrared Spectroscopy (FTIR) analysis, further supported identification of metal-oxygen bonds as well as various functional groups within the nanocomposites. Field emission scanning electron microscopy (FESEM) imaging revealed hexagonal nano disk-shaped structures of both ZnO@g-C₃N₄ nanocomposite and Sr-ZnO@g-C₃N₄ nanocomposite, a finding corroborated by Transmission Electron Microscopy (TEM) observations. Energy dispersive X-ray Spectroscopy (EDAX) analysis confirmed the elemental composition of the synthesized nanocomposites. Optical properties of pristine ZnO and Sr-ZnO@g-C₃N₄ nanocomposite were examined using Ultraviolet–Visible (UV–Visible) spectroscopy. With the increase in the percentages of Sr (from 0 to 5 %), the red shift of Sr-doped ZnO intensifies, which confirm higher levels of Sr doping. Whereas Sr with 7 and 8 % percent in ZnO, there is decrease in absorption, this is due to the increased of Sr content within the ZnO. X-ray photoelectron spectroscopy (XPS) provided insights into the oxidation states of elements, particularly in the 5 % Sr-ZnO@g-C₃N₄ nanocomposite. The Photoluminescence (PL) spectra of as-synthesized samples were carried out to check the charge carrier dynamics and defect states within the nanocomposite materials. The synthesized Sr-ZnO@g-C₃N₄ nanocomposites may find its uses in the energy storage devices, environmental remediation, and organic transformations.
