Abstract
Methyl methacrylate (MMA) is a widely used oxygen-containing volatile organic compound, functioning as both an organic solvent and additive. Therefore, the advancement of effective methods for MMA removal is of great significance. In this study, three-dimensional nanostructured carbon (CNTs/CC) anode materials were prepared through the in-situ growth of carbon nanotubes (CNTs) on carbon cloth (CC) using chemical vapor deposition (CVD). The prepared material showed outstanding adsorption-electrocatalytic degradation performance towards MMA, with a saturated adsorption capacity of 2033 mg·g−1 and complete degradation achieved after 90 min of electrification at a 100 mg·L−1 MMA concentration. The electrochemically active surface area increased to 29.8 cm2 with an Rs value of 2.35 Ω for the CNTs/CC-2 anode material, leading to enhanced ·OH generation capability and faster degradation rates. The material also exhibited excellent reusability over thirteen cycles of adsorption-electrochemical degradation of MMA, with a degradation efficiency consistently above 92 %. This research provides valuable insights for developing new materials and technologies for MMA degradation.
