Summary: This work systematically investigates the doping of sulfide ions (S2-) on photoactive MIL-53(Fe) and evaluates its performance. The study found that doping can influence the optical band-gap energy of materials, but this does not always lead to improved performance in photocatalytic reactions, especially for hybrid materials like Metal Organic Frameworks (MOFs). By varying the percentage of dopant in the reaction mixture, the study explored the effects of doping on the structural conformations and optical properties of MIL-53(Fe), demonstrating changes in band-gap energy and electron cloud expansion. The best performance in terms of MB degradation was observed for 1% S doped MIL-53(Fe) and the material showed stability even after multiple cycles, indicating potential for practical applications.

Summary: The novel semiconductor-MOF composites based on TiO2 and MIL-53(Fe) showed enhanced adsorption and photocatalytic activity for tetracycline under visible light, with the 1:2 ratio of MIL-53(Fe)@TiO2 demonstrating optimal performance. The improved performance was attributed to the n-n type heterojunction photocatalysts and synergy between MIL-53(Fe) and TiO2 in the composites, leading to enhanced visible light absorption and boosted charge carrier transfer ability.

Summary: MIL-101(Fe)/WS2 catalyst was synthesized using a solvothermal method. The physical and chemical properties of the composite material were studied using various characterizations. The photocatalysis of the catalyst in the degradation of tetracycline under visible light illumination was investigated using persulfate as a cocatalyst. The catalyst showed high efficiency in removing tetracycline, with a removal rate of over 80% within 40 minutes. The material also demonstrated good recycling capability after multiple cyclic experiments. The enhanced performance of the catalyst was attributed to the reduction of photogenerated electron-hole recombination efficiency and the activation of persulfate to produce free radicals.

Summary: The 20NaF-60P2O5-20Na2O fluorophosphate glass systems doped with 3 wt% of CoO and NiO were investigated for their optical parameters before and after gamma irradiation. The presence of defects within the glass network and the addition of transition metals were found to affect the properties of the composites. After irradiation, a red shift was observed in the dissipation factor spectrum. The energy lost at the surface of the composites was larger than the energy lost within the constituent materials. All investigated composites showed insulating behavior and exhibited increased nonlinear optical parameters after irradiation, with the CoO-doped composite showing the highest values.
