Summary: In this study, soluble portions obtained from the co-thermal dissolution of rice husk and coal were used as carbon precursors to synthesize 3D hierarchical porous carbons. The electrochemical properties of the resulting carbons were investigated, and the results showed that the composition of the carbon precursors played a crucial role in determining the characteristics of the carbon materials. Nitrogen-containing organic matters in the precursors improved the conductivity, while oxygen-containing compounds contributed to pseudocapacitance. Moreover, carbon precursors with a high content of unsaturated structures exhibited excellent electrochemical properties.
