Abstract Single atom catalysts have received widespread attention for their fascinating performance in terms of metal atom efficiency as well as their unique catalysis mechanisms comparing to conventional catalysts. Here, we prepared a high-performance catalyst of single-Cu-atom-decorated boron nitride nanofibers (BNNF-Cu) via a facile calcination method for the first time. The as-prepared catalyst shows excellent catalytic activity and good stability for converting different nitro compounds into their corresponding amines both with and without photoexcitation. By combined studies using synchrotron radiation analysis, high-resolution high-angle annular dark-field transmission electron microscopy studies and DFT calculation, dispersion and coordination of Cu atoms as well as their catalytic mechanisms are explored. The BNNF-Cu catalyst is found to have a record high turn-over frequency comparing to previously reported nonprecious-metal-based catalysts. While the performance of the BNNF-Cu catalyst is only of the middle range level among the state-of-the-art precious-metal-based catalysts, due to the much lower cost of the BNNF-Cu catalyst, its cost-efficiency is the highest among these catalysts. This work provides a new choice of support material which can promote the development of single atoms catalysts.
