TI  - Synergistic effect of GO/SrFe(12)O(19) as magnetic hybrid nanocatalyst for 
      regioselective ring-opening of epoxides with amines under eco-friendly 
      conditions.

AB  - Herein, a highly efficient magnetically separable hybrid GO/SrFe(12)O(19) 
      nanocomposite was synthesized via dispersing M-type strontium hexaferrite 
      (SrFe(12)O(19)) on graphene oxide (GO) sheets. First, SrFe(12)O(19) nanoparticles 
      (NPs) and GO sheets were prepared via chemical coprecipitation and chemical 
      oxidation of graphite powder, respectively. Chemically reduced GO (rGO) and 
      rGO/SrFe(12)O(19) were also prepared for comparison purposes. Thereafter, the 
      prepared nanostructured materials were explored by XRD, FTIR, FESEM-EDX, BET, and 
      Zetasizer analyses. All the characterizations confirm the nanoscale and the high 
      stability structures of the prepared materials. The prepared hybrid magnetic 
      nanocomposite GO/SrFe(12)O(19) exhibited a high surface area value resulting in a 
      high catalytic activity and selectivity for the epoxide ring-opening with amines 
      in neat water. The use of hybrid GO/SrFe(12)O(19) compared with pure 
      SrFe(12)O(19) and GO sheets is of great interest for using environmentally benign 
      heterogeneous nanocatalysts, for the synthesis of beta-amino alcohols, with 
      excellent recyclability under eco-friendly conditions. Moreover, a mechanistic 
      study was performed through density functional theory (DFT) calculations and Parr 
      functions to explain the observed reactivity and selectivity of SrFe-GO catalyst 
      in the epoxide ring-opening reactions.
