For the first time, Gd2ZnMnO6/ZnO ceramic nanocomposites (Gd2ZnMnO6/ZnO CNCs) were fabricated by a sol-gel auto-combustion process on the basis of a reaction between Gd, Zn and Mn nitrates and saffron as a green fuel. Gd2ZnMnO6/ZnO ceramic nanocomposites were greenly formed using saffron as a novel fuel and stabilizing agent. The morphology, phase, and anatomical purity of Gd2ZnMnO6/ZnO ceramic nanocomposites could be arranged by quantity and type of fuel, temperature, and reaction period. The specimens were explored by various microscopic and spectroscopic approaches. The uncontrolled release of carbon dioxide (CO2) by industrial processes that acidify the oceans and warm the planet has prompted scientists to try different methods to capture CO2 directly from waste water sources. The fabrication of green nanocatalysts with chemical modifications to create value-added products has many benefits. Considering the morphology of Gd2ZnMnO6/ZnO, an appropriate exteriorlayer for CO2 imbibition was created in all catalystsites. Findings disclosed that Gd2ZnMnO6/ZnO positively affected the fabrication yield of 3-aryl-2-oxazolidinones by carbon dioxide, olefins, and anilines. The product was obtained with an excellent yield of 98%. This high yield was obtained in very mild conditions, such as a pressure of 2.5 atm of carbon dioxide at 80 °C for 3 h. The technique enjoyed profitable performance and forbearance of functional groups. The retrievable catalyst was recycled up to ten times for synthesis of 3-aryl-2-oxazolidinones without significant loss in its activity. [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. [ABSTRACT FROM AUTHOR]

Ionic liquids attached to Bi7O9I3 fibers (located in the space between two fibers) can hold zinc oxide nanoparticles (NPs) well in this space and lead to the creation of a bifunctional nanocatalyst with high power (referred to as IL@Bi7O9I3-ZnO). The environmentally friendly and promising approach of photocatalytic degradation of organic dye residues serves as a means to address challenges that pose a threat to life forms. Here, an extremely effective Z-scheme heterojunction light-driven catalyst was deliberately formulated, constructed, and effectively employed for the eradication of erythrosine, methyl violet, and eriochrome black T. The outcomes acquired from the study revealed that the quantity of ZnO quantum dots directly impacts the degradation yield. The incorporation of quantum dots within the light-driven catalyst structure resulted in an enhancement in light-harvesting capability, charge transfer efficiency, and electron transfer rate. The evaluation of catalyst activity encompassed an examination of different elements in the catalyst used for producing and eliminating natural dyes. A prudent method has been suggested to optimize the collaboration between the Bi7O9I3 and ZnO groups at the nanoparticle locations on the catalyst, allowing for its recovery and subsequent reuse without any significant loss in reactivity for a minimum of ten successive cycles.

Anchoring 2,2,6,6-tetra-methylpiperidine-1oxyl radical (TEMPO) in the nanospaces a fibre of dendritic fibrous nanosilica (DFNS) together with Li2MnO3 nanoparticles (NPs) can lead to an unheard potent for the production of bifunctutional nanocatalyst (TEMPO@DFNS-Li2MnO3). The difference in the performance of DFNd2Sn2O7 photocatalyst in the removal of Acid Blue 92, Methyl orange, Acid Brown 214, Acid Black 1, eriochrome black T, and erythrosine under Visible and UV light was compared. Under the distance of TEMPO, catalytic activity in the case of Li2MnO3 nanoparticle is studied in the case of nano and bulk Li2MnO3 structures to removal of organic dyes on a multigram scale in aqueous solution. The analyses of BET, VSM, TGA, XRD, FE-SEM, EDX, UV–Vis, and TEM are used for characterizing the catalyst. The catalyst activity is evaluated considering different components of the catalyst for the synthesis of removal of organic dyes. The reasonable procedures were proposed according to the cooperation among the Li2MnO3 and TEMPO groups NPs sites over the catalyst that can be recovered and then reused without any significant reactivity loss considering at least 10 consecutive turns.

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.
