Abstract Single atom catalyst becomes a popular choice in various catalysis applications, which takes advantages of both homogeneous catalysis (e.g., high efficiency) and heterogeneous catalysis (e.g., easy catalyst recovery). The atom support plays an indispensable role in anchoring atomic species and interplaying with them for ultimate catalytic performance. Therefore, development of new support materials for superior catalysis is of great importance. Here we reported the synthesis of carbon nanofibers based on the reaction between P2O5 and N-Methyl-2-pyrrolidone. The underlying reaction process was systematically investigated by FTIR and NMR. The carbon nanofibers owned interesting -P = N- units in their chemical structure, which acts as the anchoring site for single atom catalyst. The Pt atoms anchoring carbon nanofibers exhibit high activity for hydrosilylation with a turnover frequency of 9.2×106 h−1 and a selectivity > 99%. This research affords not only a new in-situ chemical strategy to synthesize multiatom doped carbon nanofibers but also presents a potential superior support in catalysis, which opens a hopeful window in materials chemistry and catalysis applications.
