“…Titania (TiO 2 ) as a distinctive semiconductor-based photocatalyst has been widely applied in the field of water treatment thanks to its extraordinary properties such as low cost, availability, substantial chemical stability, chemical inertness, as well as exceptional photocatalytic behavior against degradation of organic pollutants. Also, it is environmentally friendly and has an antibacterial property Ide et al, 2014).…”

The new nanocomposite with various molar ratios along with magnetic properties was fabricated via precipitation (assisted by ultrasonic) procedure. The photocatalytic effects of methylene blue (∼90% degradation for optimized sample in 100 min) for finding the optimized sample performed under visible light irradiation. Moreover, the photo-antibacterial impacts of bacteria culture environments were found with an optimized sample that had effective destruction of bacteria in comparison to control group. The cytotoxicity properties of panc1 cells and magnetic behaviors of the obtained nanomaterials were evaluated and its IC50 was about 500 mg/L. As an initial step, the structural, morphological and magnetic characteristics of the fabricated nanocomposites were evaluated by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX) and MAP, UV-visible diffuse reflectance spectroscopy (DRS), and vibrating sample magnetometry (VSM) approaches. Based on SEM results, the size of nanoparticles in fabricated nanocomposite was nearly 50-70 nm for Fe 3 O 4 /SiO 2 /TiO 2 and 80-100 nm for Fe 3 O 4 /SiO 2 /TiO 2 /CeVO 4 . XRD results showed that desired nanocomposites were truly synthesized without any impurities.

“…Firstly, the FE‐SEM reveals that g‐C 3 N 4 well‐distributed on the surface of porous CS, which can make the g‐C 3 N 4 /CS with higher surface area that can prevent the g‐C 3 N 4 /CS composites aggregation, which will prompt the photocatalysis process with remarkable cyclability . Besides, there are much function groups such as oxygen‐containing and carbon groups incorporated in g‐C 3 N 4 /CS composites during the synthesis processes, which is useful for adsorption and degradation process.…”

In this work, the preparation, characterization and removal capability of hierarchically porous carbonaceous sponges and their g-C 3 N 4 /CS composites were described. Possessing a hierarchically porous structure and extremely large surface areas, g-C 3 N 4 /CS composites are demonstrated to have advantages in adsorption and photocatalytic activities. The adsorption and photocatalytic activities of the as-prepared catalysts were evaluated by the degradation of RhB, MO, and phenol. The best results showed that 97% decomposition of RhB was obtained by using g-C 3 N 4 /CS-60 composites within 20 min at 25°C under visible light irradiation. Furthermore, the g-C 3 N 4 / CS-60 composites showed remarkable regeneration stability, which maintains high photocatalytic activity after the samples are saturated. Additionally, the degradation mechanisms of RhB and the photocatalytic mechanism are explained in this paper.
