Abstract: A novel nanocatalyst design using nanomaterials through active-zone crystallisation was proposed. The hydrothermal crystallisation of amorphous dendritic fibrous nano-titanium dioxide with Ni (DFNT/Ni) sites was determined to be the main step in producing extremely active dendritic DFNT/Ni zones, which in turn dramatically enhanced their catalytic activities. DFNT/Ni was then combined with polyvinyl alcohol (PVA) by using a traditional individual-nozzle electrospinning method, and the resulting material was named PVA-DFNT/Ni. This method was utilised to produce 3-aryl-2-oxazolidinones from ethylene oxide, CO2, and anilines. The prepared catalytic apparatus was eco-friendly and had the advantages of high catalytic activity, ability to improve the reaction mixture, and reusability without a considerable decrease in efficiency. It is extracted in the straight and adoptive chemical fixation of flue-gas CO2 obtained from industrial emissions, thereby achieving high degrees of CO2 absorption and conversion.

In this study, a well-defined, novel NHC-Ni complex was developed and used to catalyze the N-arylation of alkyl- and arylamines with arylboronic acids in a rare version of Chan-Lam coupling. Although the same coupling using copper catalysts has been widely studied, the nickel-catalyzed version is rare and normally requires 10–20 mol% catalyst loading. This novel NHC-Ni complex in combination with 4,4′-dimethyl-2,2′-bipyridine, however, proved to be an effective catalyst that lowered the required catalyst loading to only 2.0 mol%.
