In this article, we present the synthesis of calcium sulfate nanoparticles (CaSO 4 NPs) from waste chalk powder by the calcination method. These CaSO 4 NPs were utilized for the construction of a mesoporous graphitic carbon nitride-calcium sulfate (mpg-C 3 N 4 -CaSO 4 ) photocatalyst. Synthesized materials were confirmed by several characterization techniques. The photocatalytic performance of the synthesized samples was tested by the degradation of methylene blue (MB) in the presence of both UV−vis light and sunlight. The efficiency of photocatalytic degradation of MB dye using the optimized mpg-C 3 N 4 -CaSO 4 -2 composite reached 91% within 90 min in the presence of UV−vis light with superb photostability and recyclability after five runs compared to individual mpg-C 3 N 4 and CaSO 4 NPs and reached 95% within 120 min under sunlight. Histotoxicological studies on fish liver and ovary indicated that the dye containing the solution damaged the structure of the liver and ovary tissues, whereas the photodegraded solution of MB was found to be less toxic and caused negligible alterations in their typical structure similar to the control group.

Photocatalytic degradation under ultra-low powered light is a viable advanced oxidation process technique against extensive emerging contaminants. As a new and remarkable class of nanoporous materials, metal-organic frameworks (MOFs), attract interest for the supreme adsorptive and photocatalytic functionalities. An outstanding MOF, MIL-101(Fe) chosen as a photocatalyst template for the synthesis of α-Fe2O3 by a simple thermal modification to improve the structural properties toward methylene blue (MB) eradication. Octahedron-like α-Fe2O3 photocatalyst (Modified MIL-101(Fe), M-MIL-101(Fe)) was superior in dispersion and separation properties in aqueous medium. Moreover, the adsorptive and catalytic performance was increased for modified form by ~ 7.3% and ~ 17.1% compared to pristine MIL-101(Fe), respectively. Synergistic improvement of MB removal achieved by simultaneous adsorption/degradation under 5-W LED irradiation. Parametric study indicated an 18.1% and 44.5% improvement in MB removal was observed by increasing pH from 4 to 10, and M-MIL-101(Fe) dose from 0.2 to 1 g L−1, respectively. MB removal followed the pseudo-second-order kinetics model and the process efficiency dropped by 38% as MB concentration increased from 5 to 20 mg L−1. Radical trapping tests revealed the significant role of $${\mathrm{OH}}^{.}$$ OH . and electron radicals as the major participants in dye degradation. A significant loss in the efficiency of M-MIL-101(Fe) was observed in the reusability tests that is good to study further. In conclusion, a simple thermal post-synthesis modification on MIL-101(Fe) improved its structural, catalytic, and adsorptive properties against MB.

“…10,11 Among these, ZnO is a promising candidate due to its superior oxidation resistance, stability, low cost, and non-toxicity, causing no secondary pollution. 12,13 However, the high band gap energy of ZnO (3.3 eV) leads to rapid recombination between holes (h + ) and electrons (e − ) resulting in reduced photocatalytic activity. 14,15 Consequently, researchers have focused on enhancing the efficiency of ZnO by combining it with other semiconductors, using carriers such as graphene, graphene oxide, and carbon nanotubes, doping metals or nonmetals, to reduce band gap energy, and the recombination potential of holes (h + ) and electrons (e − ).…”
