Effect of extraction pre-treatment of larch bark on the structural and electrochemical characteristics of the carbon product

Abstract

Abstract This paper presents the synthesis of carbon material from the untreated and extracted larch bark. The influence of the extracting reagents (water, ethanol, hydrogen peroxide, and sodium hydroxide) on the structural changes of ash components of the bark was revealed. It is assumed that one of the reasons for the development of the porous structure of carbon products during carbonization of the extracted bark is associated with a decrease in ash content. It was found that the carbon product obtained from washed-out water bark has the highest value of the specific surface area (401 m2/g) and the largest accumulation of electric charge.
