Carbon nanotubes (CNTs) have attracted attention as high-performance materials. However, conventional synthesis methods face challenges in large-scale production. We are focusing on a novel method for synthesizing CNTs under atmospheric pressure and in a short time, which employs FeAlOx catalysts and waste plastic through microwave heating. However, the obtained CNTs contain a large amount of residual catalysts, which poses a barrier to practical applications. In this study, to remove the residual catalyst, we conducted microwave heating treatment in a dilute nitric acid solution and attempted efficient removal through selective heating.
