The few layered boron carbon nitride nanosheets (BCNNSs) have attracted widespread attention in the field of heterogeneous catalysis. Herein, we report an innovative one-pot route to prepare catalyst BCNNSs-encapsulated sub-10 nm highly dispersed nanoiron particles. Then novel was used Fischer–Tropsch synthesis for first time and it exhibited high activity superior stability. At a temperature 320 °C, CO conversion could reach 88.9%, corresponding catalytic per gram iron (iron yield, FTY) 0.9 × 10–4 molCO gFe–1 s–1, more than 200 times higher that pure iron. Notably, no obvious deactivation observed after 1000 h running. enhanced stability can be ascribed special encapsulated structure. Furthermore, formation mechanism nanoparticle also elaborated. This approach opens way designing metal nanoparticles with both reactivity nanocatalysts hydrogenation application.
