Efficient and selective cycloaddition of carbon dioxide, amines, and alkenes using Gd2ZnMnO6/Zn2MnO4 supported on dendritic fibrous nano-titanium

[Display omitted] •DFNT@Gd2ZnMnO6/Zn2MnO4 nanoparticles were synthesized through a straightforward method.•The catalyst’s properties were specified by FTIR, XRD, BET, EDX, SEM, VSM, TEM, and ICP analyses.•DFNT@Gd2ZnMnO6/Zn2MnO4 was deployed to synthesis of 3-aryl-2-oxazolidinones by olefins, anilines, and carbon dioxide. The co-fabrication of a phase junction and fibrous structure has been demonstrated to enhance the catalytic ability, catalytic performance, and separation of nano titanium oxide. Nevertheless, despite these benefits, there remains a critical need for facile and environmentally sustainable fabrication methods. In this study, we present an innovative approach to synthesizing dandelion-like TiO2 with anatase/TiO2 phase interfaces and a highly specific exterior level using a user-friendly and green deep eutectic solvent-tuning method. This impressive outer layer is the result of the 3D-ranked assembly of 2D ultrathin nanosheets with mesopores. Additionally, we have successfully fabricated Gd2ZnMnO6/Zn2MnO4 nanospheres on dendritic fibrous nanotitanium (DFNT@Gd2ZnMnO6/Zn2MnO4) via a facile synthetic pathway. Notably, the overall mapping of the DFNT@Gd2ZnMnO6/Zn2MnO4 composite remained largely unchanged after the loading of Gd2ZnMnO6/Zn2MnO4, and its mesoporous architecture and crystalline morphology were preserved. The investigation of diverse DFNT@Gd2ZnMnO6/Zn2MnO4 configurations as a nanocatalysts for the preparation of 3-aryl-2-oxazolidinones by anilines, carbon dioxide, and olefins was also conducted. It demonstrated appropriate stability over ten cycles, indicating its potential as a highly proficient catalyst to mitigate environmental concerns.
