The aims of this work were to synthesize and characterize the activated zeolite modified by tungstic acid (TA-AZ) and also evaluate its performance in LA esterification. We employed the wet impregnation approach and ultrasonication-assisted method to produce TA-AZ catalyst with different concentrations of TA (15, 20, and 25 wt%). Fourier transform infrared (FTIR), ammonia-temperature programmed desorption (NH₃-TPD), X-ray diffraction (XRD), scanning electron microscope with an energy dispersive X-ray spectrometer (SEM-EDX), transmission electron microscope (TEM), and surface area analyzer (SAA) were among the analytical methods used to investigate the chemical and physical characteristics of AZ and TA-AZ catalysts. The liquid yields from LA esterification were analyzed by GC-FID. The findings indicated that the 25TA-AZ catalyst exhibited the highest acidity, reaching 3.65 mmol/g. The presence of TA in AZ resulted in an enhancement of LA conversion and an increase in EL yield.

Among the avrious remediation methods, photocatalysis is considered optimal due to its efficiency and eco-friendly nature. Therefore, the development of highly active, visible-light-responsive, and noble-metal-free photocatalysts for the elimination of toxic heavy metal ions from wastewater is highly desirable. In this study, a facile two-step method, comprising solvothermal and hydrothermal, was used to synthesize visible-light-responsive CdS/MoS₂ heterojunctions (CM-HJs). Extensive structural characterization was performed to assess the crystal structure (XRD and XPS), morphology (SEM and BET), and optical (UV-Vis) properties of the as-synthesized photocatalysts. Aquatic Cr(VI) photoreduction was conducted on these photocatalysts under visible light irradiation. The results revealed the high photocatalytic activity and photostability of CM-HJs for Cr(VI) reduction compared to the bare CdS. Among the heterojunctions, CM-10 (10 wt % MoS₂) exhibted the highest acvtivty, reducing 99.04% of Cr(VI) within 60 min. The enhanced photocatalytic activity can be attributed to its high light harvesting capability and efficient separation and transportation of the produced electron-hole pairs due to the intimate contact interfaces and matching band potentials of CdS with MoS₂. Based on the literature and experimental evidence, a photocatalytic mechanism for the photoreduction of Cr(VI) is discussed in detail. The effect of different parameters; like the amount of photocatalyst, amount of Cr(VI), and pH were also evaluated.

The SEM results revealed that MnWO₄ and CuWO₄nanoparticles were well organized on the exterior of g-C₃N₄ forming interesting spherical particle morphology. Under optimized conditions, the nanocomposites MnWO₄@g-C₃N₄ and CuWO₄@g-C₃N₄ exhibited an impressive 98 and 98.5% removal of DBT, respectively from the model fuel (100 mg/L) within 180 min at a temperature of 45 °C using 1 mL of oxidant and 0.1 g of catalyst amount. Furthermore, the catalytic activity of composites was investigated for real fuel desulfurization and promising results were achieved. Moreover, the fuel properties were in accordance with ASTM specifications. The study found that the desulfurization reaction followed the pseudo 1st order kinetic models and the negative ∆G indicated a spontaneous method. The nanocomposites exhibited promising reusability as it could be used up to five times without significantly reducing their ability to desulfurize fuel oil.
