Abstract
En 中文
This study reports the design and fabrication of a series of heterogeneous N,S-rGO/NiFe2O4-X% nanocomposites, where X represents the weight percentage of NiFe2O4. Nitrogen and sulfur dopants were deliberately introduced into the graphene oxide framework, followed by the concurrent anchoring of NiFe2O4 nanoparticles within the graphene oxide layers through a controlled hydrothermal approach. The structure, morphology, optical characteristics, and photocatalytic activity of the nanocomposites were precisely characterized using XRD, XPS, FTIR, Raman spectroscopy, FESEM, TEM, EDAX, elemental mapping, DRS, BET, PL, and EIS, which collectively validated the successful integration of the designed components.
