摘要

•A simple method to realize the modulation of N-doped carbon content and macropore.•Optimizing microwave absorbing property by tuning Zn/Co molar ratio in precursor.•High-content pyridine N contributes to obtaining enhanced polarization loss.•The strong RL intensity can reach to −56.7 dB and EAB achieves as 8 GHz.
