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.

Glucose can form carbon material under hydrothermal conditions. Thus, carbon-layer-coated nickel sulfide nanoparticles were prepared using a one-step method with as the primary phase. The effect of glucose mass on structure and electrochemical properties was studied in detail. size decreased after surface coated by layer, forming uniform spherical particles 200–300 nm. layer thickness ∼3 nitrogen adsorption–desorption test revealed that specific area pristine 2.7 m2 g–1. Under optimal conditions, (NixSy-0.5) depicted 15.2 high provided additional electrochemically active sites. glucose-derived could be utilized conductive agent to enhance electron transport electrode. Electrochemical results capacitance NixSy-0.5 612.5 C g–1 at 1 A g–1, higher than (381.7 g–1). hybrid supercapacitor (HSC) assembled positive electrode commercial activated (AC) negative exhibited energy density 47 Wh kg–1. retention rate is (99%) 20 000 cycles. This study demonstrated simultaneous preparation sulfide–carbon composites feasible strategy for preparing economical efficient materials.
