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.
