本研究利用溶胶-凝胶方法创建CoFe2O4/g-C3N4纳米复合材料(NC),并探索了几种分析方法来评估物理,基于XRD的化学和光学特性,FTIR,UV-vis,所制备的纯CoFe2O4、g-C3N4和CoFe2O4/g-C3N4NC的SEM/EDS和XPS。XRD结果表明,制备的g-C3N4,CoFe2O4,分别呈六方相和立方相,而g-C3N4/CoFe2O4NC表现出两相混合。纯g-C3N4,CoFe2O4和g-C3N4/CoFe2O4NC值的能带隙为。,2.75、1.3和2.4eV。作为光催化剂,合成材料用于罗丹明-B(RhB)染料的分解。最后,CoFe2O4/g-C3N4NC在可见光刺激下对RhB染料崩解具有良好的光催化性能。根据诱导的可见光,发现CoFe2O4/g-C3N4NC在120分钟内发生光催化降解的速率为57%,与纯催化剂如CoFe2O4(28%)和g-C3N4(10%)相比,该速率更高。这些结果表明,与纯材料相比,制备的NC在光催化过程中有效地工作。
The present research utilizes a sol-gel approach to create a CoFe2O4/g-C3N4 nanocomposite (NC) and explored several analytical methods to evaluate physical, chemical and optical based characteristics via XRD, FTIR, UV-vis, SEM/EDS and XPS for the prepared pure CoFe2O4, g-C3N4, and CoFe2O4/g-C3N4 NC. The XRD results show that the prepared g-C3N4, CoFe2O4, exhibits hexagonal and cubic phases respectively, whereas the g-C3N4/CoFe2O4 NC exhibit mixing of two phases. The energy band gaps for pure g-C3N4, CoFe2O4 and g-C3N4/CoFe2O4 NC values are viz., 2.75, 1.3, and 2.4 eV. As photocatalysts, synthesized materials were utilized for the decomposition of Rhodamine-B (RhB) dye. Finally, the CoFe2O4/g-C3N4 NC showed good performance of photocatalysis for RhB dye disintegration under the stimulus of visible light. According to the induced visible light, the rate at which the photocatalytic degradation occurs for the CoFe2O4/g-C3N4 NC was found to be 57% in 120 min and this is greater when compared with pure catalysts like CoFe2O4 (28%) and g-C3N4 (10%). These outcomes suggest that the prepared NC have efficiently worked during the photocatalytic process compared with its pure materials.
