Abstract Heteroatom doping and structural modification can significantly improve the electrochemical properties of carbon materials, but it is difficult to achieve synchronous control two. To this end, N‐doped porous material (BCNK) was synthesized using bombyx mori silk as source, melamine KHCO 3 activators. When only added, prepared (BCN) increases heteroatom content. (BCK) specific surface area pore volume. The microstructure heteratom content materials be controlled simultaneously by adding two activators at same time. Electrochemical tests show that performance BCNK higher than BCN BCK. It worth mentioning much lower BCK, indicating increasing more conducive achieving excellent area. This study not provides a new way for application in supercapacitors, also enables researchers re‐understand relationship between structure materials.
