Poultry feather is renewable, inexpensive and abundantly available. It holds great business potentials if poultry feather can be converted into valuable functional materials. Herein, we describe a strategy for the catalytic conversion of chicken feather waste to Ni₃S₂-carbon coaxial nanofibers (Ni₃S₂@C) which can be further converted to nitrogen doped carbon nanotubes (N-CNTs). Both Ni₃S₂@C and N-CNTs exhibit high catalytic activity and good reusability in the reduction of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) by NaBH₄ with a first-order rate constant (k) of 0.9 脳 10^鈥? s^鈥? and 2.1 脳 10^鈥? s^鈥?, respectively. The catalytic activity of N-CNTs is better than that of N-doped graphene and comparable to commonly used noble metal catalysts. The N content in N-CNTs reaches as high as 6.43%, which is responsible for the excellent catalytic performance. This strategy provides an efficient and low-cost method for the comprehensive utilization of chicken feathers. Moreover, this study provides a new direction for the application of N-CNTs.
