Preparation and Characterization of Phenolic Resin/Bamboo Based Composite Activated Carbon for Supercapacitors
摘要
Abstract
To investigate the effect of phenolic resin addition on the microstructure and electrochemical properties of carbon materials,and to obtain a relatively economical method of preparing carbon materials for supercapacitors,phenolic resin/bamboo based composite activated carbon was prepared by KOH activation using bamboo waste as raw material and phenolic resin as modifier.The results showed that the microstructure of the composite activated carbon was affected by the addition of phenolic resin.The specific surface area and total pore volume of the composite activated carbon with the resin addition of 15%～35%increased.The average pore diameter decreased,providing more adsorption sites for storage charge.The specific surface area and total pore volume of the composite activated carbon were increased by 28.5%and 29.2%,respectively,and the average pore size was reduced to 1.78 nm compared with that of the bamboo-based activated carbon when 35%of phenolic resin was added;the specific capacitance at a current density of 0.5 A·g-1 reached 263.85 F·g-1,which was 53.3%higher than bamboo activated carbon.The results indicated that the electrochemical properties of activated carbon prepared by adding phenolic resin were obviously improved.关键词
