Summary: This study investigated the effects of carbohydrate and lignin content in biomass on biochar production, and evaluated the adsorption behaviors of diazinon on biochar obtained from delignified oak. Delignification control the lignin content in biomass, resulting in decreased lignin content and increased cellulose content in delignified oak. The specific surface area and total pore volume of biochar from delignified oak were higher compared to raw material, and the removal efficiency of diazinon increased with delignification time. The adsorption of diazinon to biochar followed the Langmuir model.

Summary: Lignocellulosic biomass pyrolysis and gasification technologies have been widely explored for the production of bio-oil, syngas, and process heat. The byproduct of this process, biochar, has attracted attention for its potential value in carbon utilization and carbon neutralization. However, there is a lack of systematic studies on the chemical composition and structure changes during the carbonization process of lignocellulosic biomass, as well as the origin of biochar reactivity. This article provides insights into the decomposition/transformation mechanisms of lignocellulosic biomass and the reactivity-related compositions of biochar. The discussion also expands on the origin of biochar's reactivity and potential ways to express its reactivity. The outlook section highlights future directions and prospects for further research and green applications.

Summary: This study aimed to investigate the adsorption behavior of biochar on pesticides and its impact on the degradation of pesticide residues in soil. The results showed that rice straw biochar had similar adsorption characteristics to the selected triazine herbicides, and the adsorption amount increased with higher preparation temperature and the amount of biochar. The competition adsorption of the herbicides on biochar was lower compared to individual adsorption. Biochar addition increased the degradation of the evaluated herbicides in soil, indicating the potential use of rice straw biochar as a sorbent for pesticide removal.

Summary: This study investigates the adsorption characteristics of biochar prepared from hydrothermally pretreated biogas residue (HBRBC) for tetracycline (TC). The results show that hydrothermal pretreatment enhances the mesoporous structure, carbon defects, and polarity of biochar, thereby improving its adsorption performance. Additionally, hydrothermal pretreatment leads to changes in the composition and functional groups of biochar. HBRBC exhibits high adsorption capacity for TC over a wide pH range and in the presence of coexisting ion interference.
