“…In addition, heterocyclic sulfides and their derivatives cannot be removed completely due to resistance at high temperatures. Therefore, alternative desulfurization techniques have been used, such as extraction, bio-desulfurization, adsorption, photooxidation, and oxidation [4,5]. Among these technologies, oxidative desulfurization (ODS) offers advantages such as simplicity, lower costeffectiveness, and carrying out at middle operating conditions [6].…”

In this study, the incipient wetness impregnation (IWI) method was used to prepare tin oxide nanoparticles supported on reduced graphene oxide nanosheets (SnO2/rGO). Characterize of catalyst composite were analyzed by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), Field emission scanning electron microscope (FESEM), energy dispersive X-ray spectroscopy (EDX), and Raman spectroscopy. The activity of the SnO2/rGO catalyst was evaluated in the catalytic oxidation process of dibenzothiophene (DBT) for modeled oil and diesel fuel in the presence of H2O2 as an oxidant. Optimum reaction conditions (the loading quantity of the tin oxide, the concentration of dibenzothiophene, the time of reaction, the temperature, the amount of oxidant, and the catalyst dosage) were investigated in a batch reactor. High-value of dibenzothiophene (DBT) removal from modeled oil samples was 79% at temperature = 60 ◦C, reaction time = 90 min, catalyst dosage = 0.04 g, amount of H2O2 = 0.375 mL, and 385 ppm concentration of dibenzothiophene. Catalyst activity at the same operating condition was also investigated for diesel fuel and the removal of sulfur was 41%

“…A variety of optoelectronic devices, including diodes, solar cells, and panel displays, among others, increasingly depend on transparent conductive materials (TCMs) as functional components [1][2][3]. ITO, an indium-doped oxide, has garnered significant attention as one of the transparent conducting oxides in recent times.…”

“…Metal oxide-loaded alumina nanoparticles that included 12.5 % ZnO and 12.5 % MgO significantly increased the effectiveness of oxidative desulfurization. The homemade Nano catalyst was characterized by applying the precipitation technique to the surface area of the Nano alumina analyzer and N 2 adsorption [3]. Magnesium oxide nanoparticles were synthesized using the chemical bath method in a range of concentrations, exploring their effect on morphologies, particle size, and energy gap in the fabrication of a UV detector [4].…”

Transparent conducting oxides (TCO) offer the uncommon functional combination of being both transparent and electrically conductive. For this reason, this study is concerned with the preparation of the triple heterojunction consisting of magnesium oxide, alumina, and ITO using a pulsed laser deposition method with a laser intensity of 3 J. Alumina bulk pellets in propanol were irradiated (Nd:YAG) at a wavelength of 1064 nm. Laser ablation was performed at a laser intensity of 3 J and deposited on ITO, which was then left to dry for 24 hours. The same method was used to attain magnesium nanoparticles, which were spin-coated on the previous sample and dried in a 500 °C oven for 4 hours. Then the properties of nanoparticles were investigated using X-ray diffraction, UV spectroscopy, and scanning electron microscopy (SEM). The results were obtained by UV and XRD analyses. From SEM images, the average size of the synthesized nanoparticles was determined to be about 25–35 nm. Aluminum oxide, MgO, and ITO are 1-D nanostructured semiconductors that function as transparent conducting oxide thin film while also increasing absorption in the visible spectrum. ITO is identified as an appropriate electrode material for infrared photoelectric devices.

“…Shi et al [31] found that the lower electron density upon sulfur atom led to lower activity in removing of sulfur related to the electron density of thiophene, BT, DBT and the oxidation reactivity of the model sulfur compounds has been conducted based on the oxygen as an oxidant and complex solid as a catalyst. Abdulateef et al [22] have used the ODS of sulfur compounds found in kerosene using several different reactor temperatures, different reaction time and different catalyst weight in a batch reactor based on a prepared nano catalyst of manganese oxide (ZnO-MgO/ɣ-Al2O3), and high sulfur removal was observed. Nawaf et al [21] have examined the ODS process of kerosene based on composite nano catalyst (18%ZnO/ɣ-Al2O3) prepared by thermal coprecipitation method in a batch system.…”

Oxidative desulfurization process (ODS), enhanced with a novel metal oxide (Ag ions) as an active component over nano-zeolite that has not been reported in the literature, is used here to improve the fuel quality by removing mercaptan (as a model sulfur compound in the light naphtha). Nano-crystalline (nano-support (Nano-zeolite)) composite is prepared by Incipient Wetness Impregnation method loaded with a metal salt to obtain 0.5, 1 and 1.5% of Ag2O3 over Nano-zeolite. The new homemade nano-catalysts (Ag2O3/Nano-zeolite) prepared are characterized by Brunauer–Emmett–Teller (BET) (surface area, pore volume and pore size), X-ray Diffraction (XRD), Fourier Transform Infra Red (FTIR), and Scanning Electron Microscopy (SEM) analysis. The ODS process is then used to evaluate the performance of the catalysts for the removal of sulfur at different reaction temperatures (80–140 °C) and reaction times (30–50 min) in a batch reactor using the air as oxidant. 87.4% of sulfur removal has been achieved using 1% silver oxide loaded on Nano zeolite (1% of Ag2O3/Nano-zeolite) giving a clear indication that our newly designed catalyst is highly efficient catalyst in the removal of sulfur compound (mercaptan) from naphtha. A new mechanism of chemical reaction for sulfur removal by oxygen using the new homemade catalyst (Ag2O3/Nano-zeolite) prepared has been suggested in this study. The best kinetic model parameters of the relevant reactions are also estimated in this study using pseudo first order technique based on the experimental results.
