Synthesis of a Carbon-Containing Composite Based on Aspen Wood and Its Structural and Electrochemical Properties

Highly porous ZnO/carbon composite with a specific surface area of up to 2050 m 2 g –1 was prepared from aspen sawdust modified with zinc chloride. The effect of temperature, modifier, and long preliminary keeping in water on the structural characteristics of the final product was examined. The possibility of using porous materials synthesized from aspen wood waste as electrode materials was demonstrated. As shown by cyclic voltammetry, the apparent specific electrical capacitance reaches 104 F g –1 .
