In the present study, the superhydrophobic coating was synthesized by spherical silica nanostructures modified with organosilane compounds for glass surfaces. To optimize the conditions in terms of cost-effectiveness and create a super-hydrophobic coating with a high contact angle, the response surface method of the central composite design (CCD) model was performed for the StÖber method, and the contact angle was defined as the response surface for the model. Tetraethoxysilane (TEOS) was used as a precursor and poly(dimethylsiloxane) (PDMS) was used to modify the surface of a spherical silica nanostructure synthesized by a one-step sol–gel method using a base catalyst. The accuracy of the research was checked by the contact angle measurement test and an angle of 162° was obtained. XRD, FT-IR, EDS, SEM, DLS, and AFM analyzes were performed to investigate the synthesis of silica nanostructure. Chemical resistance was performed in acidic, neutral, and alkaline environments and the contact angles were 127°, 134°, and 90°, respectively, which indicates that the coating created on the surface glass has good chemical resistance in acidic and neutral environments.

To meet the requirements of sulfur standards, the desulfurization of liquid fuels is crucial. Oxidative desulfurization (ODS) has been widely employed to desulfurize liquid fuels. Various techniques can be combined with ODS to increase its efficiency. The present study surveys recent advances in the techniques of ultrasound-assisted oxidative desulfurization, plasma oxidative desulfurization, microwave-assisted oxidative desulfurization, hydrodynamic cavitation-assisted oxidative desulfurization, photocatalytic oxidative desulfurization, electrochemical oxidative desulfurization, magnetic field-assisted oxidative desulfurization, and bio-oxidative desulfurization. The advantages, drawbacks, and prospects of each method to desulfurize liquid fuels have been reviewed. All of these methods are in the research and development phases and often are at the laboratory stage. However, ultrasoundassisted ODS has been extensively investigated and its usage in industrial plants has been reported. The industrial applications of ODS and techniques assisted with ODS require more investigation.

“…However, the intensive use of petroleum, especially in transportation, causes gas emissions to be produced, namely SO x (Mahmoudi et al, 2021) . SO x signi cantly contributes to air pollution, acid rain, and damage to the gas emission section of vehicles (Abedini et al, 2021;Kang et al, 2018;Mousavi-Kamazani et al, 2020).…”

In the present study, composite layer double hydroxide-metal oxide (Ni/Al-TiO2 and Ni/Al-ZnO) was successfully prepared and used as catalyst of oxidative desulfurization of dibenzothiophene. Characterization of catalyst was used XRD, FTIR, and SEM-EDS. The structure of Ni/Al-LDH, TiO2, and ZnO in composite Ni/Al-TiO2 and Ni/Al-ZnO was consistent, which also indicated that the preparation of composite did not change the form of precursors. FTIR spectra of Ni/Al-TiO2 and Ni/Al-ZnO absorption band at 3398, 1639, 1339, 832, 731, and 682 cm−1. The catalysts have an irregular structure, TiO2 and ZnO adhere to the surface of Ni/Al LDH. The percent mass of Ti and Zn on the composite at 29.3% and 18.2%, respectively. The acidity of Ni/Al LDH increased after being composited with TiO2 and ZnO. The optimum reaction time, dosage catalyst, and temperature were 30 min, 0.25 g, and 50°C, respectively, and n-hexane as a solvent. The percentage conversion of dibenzothiophene on Ni/Al-LDH, TiO2, ZnO, Ni/Al-TiO2, and Ni/Al-ZnO were 99.44%, 91.92%, 95.36%, 99.88%, and 99.90%, respectively. The catalysts are heterogeneous system and the advantage is that can be used for reusability. After 3 times catalytic reactions, the conversion of dibenzothiophene still retains more than 80%, even Ni/Al-TiO2 and Ni/Al-ZnO composites still 97.79% and 98.99%, respectively.
