The development of N‐doped catalysts from biomass remains an important objective of chemical research. In this study, a simple fabrication process for renewable N‐doped carbon (RNC, N content 6.5 wt%) is provided to take the inexpensive of soybean pulp for efficient chemoselective hydrogenation of halogenated nitrobenzenes. The RNC precursor was activated by KOH and carbonized at high temperatures; this resulted in dramatically increased specific surface area and accessible active sites. Natural N atoms in the carbon matrix provide out‐of‐domain charge and modulate the electronic property of RNC as a metal‐like structure. The obtained RNC material shows excellent catalytic activity in the catalytic hydrogenation of halogenated nitrobenzenes using N 2 H 4 ⋅H 2 O as the reducing agent under mild reaction conditions. The catalytic activity of RNC only slightly decrease after repeated reaction cycles.
