Description
Biochar has drawn intensive attention, particularly in environmental remediation, such as the removal of various pollutants in water and air. However, dearth of research on the removal efficiency of VOCs on biochar. Honeycomb-like tubular biochars (HT-Bs) were synthesized from pre-treated corn stalks (CS) for the removal of acetone gas. The honeycomb-like tubular structure exhibited great influence on the adsorption efficiency of biochar resulting in higher acetone removal capacity. In this study, physicochemical and morphology characterization results of the HT-Bs synthesized from pre-treated CS, for the removal of acetone gas were analyzed. The impregnation ratio with ZnCl2 and biomass pore structure crucially influenced the formation of HT-Bs structure and the yield of biochar produced compared to the heating rate and residing time. The CS impregnated at a ratio of 1:0.2 exhibited more stable honeycomb-like structure, constructed from high amounts of tubular structure, and larger porosity. The influence of the im-pregnation ratio and the porosity of the HT-B on the acetone gas removal efficiency was investigated. The adsorption performance of HT-Bs were analyzed by adsorbed acetone gas. This study addressed the implementation of sustainable development goals (SDGs) that could be achieved by the application of biochar and effective adsorbent for the adsorption of VOCs.
