Cutting off refractory organosulfur compounds is an immense need in the modern age of petroleum refineries. The oxidation of these hard organosulfur compounds is dynamic in the course of deep oxidative desulfurization. Atmospheric molecular oxygen is an organic, innocuous, abundant, and economical oxidant. Microorganisms synthesize dendritic fibrous nanoparticles (DFNPs) in exposure to metal ions. In this research, microorganisms were used to produce Zn2MnO4 DFNPs in a biological process instead of a chemical method as a nanocatalyst. This biogenic nanoparticle has been used for the first time as a recyclable catalyst with external magnet and efficient in desulfurization process under environmentally friendly conditions with support of oxygen green oxidant, at atmospheric pressure, at low temperature, green water extraction agent, Distilled with the help of ultrasound as a source of green energy in a shorter time. This strategy has marvelous profits, including high economic yield and tolerance of functional groups. The present study underscores how metabolic processes in anaerobic bacteria could be mixed with green chemical technologies to generate extremely efficient catalytic reactions for ultrasound-assisted oxidative desulfurization of simulated fuel, natural gasoline, and sulfur mustard analogs.

Here, first, the Nd2Sn2O7 NPs were greenly generated in the participation of gum of ferula assa-feotida of SnCl4.5H2O and Nd(NO3)3. The uncontrolled release of CO2 by industrial processes that acidify the oceans and warm the planet has prompted scientists to try different methods to capture CO2 directly from wastewater sources. Considering the morphology of Nd2Sn2O7 NPs, an appropriate exterior layer for CO2 imbibition was created in all catalyst sites. Findings disclosed that Nd2Sn2O7 NPs positively affected the fabrication yield of 3a,4-dihydronaphtho[2,3-c]furan-1(3H)-one through a three-factor coupling reaction of alkynes, allylic chlorides, and carbon dioxide. The technique enjoyed profitable performance and forbearance of functional groups. [ABSTRACT FROM AUTHOR]

Simultaneously fabricating a fibrous structure and phase junction has the potential to improve the separation of nano titanium oxide, catalytic activity, and catalytic power. It is important to maintain an easy and environmentally-friendly fabrication process. This research led to the successful creation of a sophisticated type of titanium oxide, featuring a TiO2/anatase phase interface and a significant unique outer layer. A unique exterior level was created using an eco-friendly method and modification of deep tunable solvents. This resulted in a 3D structure made of 2D ultrathin nanosheets with mesopores. We synthesized Dy2Sn2O7 nanoparticles and combined them with aromatic ring-doped C3N4 nanosheets (Ar-C3N4; Ar = Ph, Pm, Py,) which were deposited onto nanofibrous titanium (Dy2Sn2O7@Ar-C3N4/NFT) as a nanoceramic. The employment of NFT was discovered to supply numerous hydroxyl groups, enabling consistent loading of Ar-C3N4 via molecular binding engagement. By exploring the potential of fibrous structure in nanoceramic production, a novel and innovative approach is being pursued, which has the potential to revolutionize the field of catalysis in the petroleum industry. Moreover, Ar-C3N4 could adjust fibre sizes and offer active amino group adsorption sites, aiding in chemisorption with organic compounds. The surface features and porous architecture of the Dy2Sn2O7@Ar-C3N4/NFT composite were preserved after Dy2Sn2O7@Ar-C3N4 loading, suggesting the maintained crystalline form. This remarkable catalyst, displays an impressive capability in facilitating the desulfurization process, all while adhering to environmentally friendly conditions. Moreover, in order to further enhance its sustainability credentials, this catalyst has been crafted with the support of oxygen green oxidant, ensuring a greener approach to the desulfurization process. Remarkably, this entire process is carried out at atmospheric pressure and at low temperatures, ensuring energy conservation and minimizing any potential adverse effects.Graphical Abstract: Simultaneously fabricating a fibrous structure and phase junction has the potential to improve the separation of nano titanium oxide, catalytic activity, and catalytic power.
