One‐step ultrasonic production of the chitosan/lactose/g‐C₃N₄ nanocomposites with lactose as a biological capping agent: Photocatalytic activity study

Abstract

In this work, the basic and applied purpose was to synthesize and modify chitosan/lactose nanocomposites with g-C 3 N 4 structures using the ultrasonic-assisted electrospinning method. We evaluated effective photocatalytic of chitosan/lactose/g-C 3 N 4 nanocomposites to photodegrade methyl red, methyl orange, and methyl blue in different nanophotocatalyst concentration such as 0.1-1%g/L in pH 6.5. According to the experimental results, it was found that nanocomposites in different concentrations of g-C 3 N 4 had high potential in degradation of organic compounds. The lactose structures as a green capping agent and stabilizer modified chitosan surfaces to produce uniform particle size distribution. Different lactose concentrations like 0.1-0.5%wt/vol indicate a particle size range between 270 and 422 nm. The obtained as-synthesized nanomaterials were characterized by scanning electron microscope, energy-dispersive X-ray spectroscopy, transmission electron microscopy, X-ray diffraction (XRD), Fourier-transform
