Biomass-derived carbon materials (BDCs) are highly regarded for their renewability, environmental friendliness, and broad potential application. A significant advantage of these lies in the high degree customization physical chemical properties, especially terms pore structure. Pore engineering is a key strategy to enhance performance BDCs critical areas, such as energy storage, catalysis, remediation. This review focuses on engineering, exploring definition, classification, adjustment techniques structures, well how factors affect application energy, Our aim provide solid theoretical foundation practical guidance facilitate rapid transition from laboratory industrial applications.

Methane (CH₄), a potent greenhouse gas (GHG) with high global warming potential, significantly contributes to urban GHG emissions. Organic mulching, commonly practiced in forestry, may promote CH₄ emissions via anaerobic decomposition; yet its impact on the carbon budget has largely been unexamined. Biochar shown promise mitigating agricultural soils, but effectiveness mulched systems remains unknown. This study employed mesocosm experiment investigate effects of organic mulches (woodchips and bark) biochar amendments (50 t/ha), applied either surface (top-dressed) or incorporated (mixed), fluxes CH₄, CO₂, H₂O. Fluxes were measured using an off-axis integrated cavity output spectroscopy analyzer. Results indicate that soils emitted at 1.0-1.5 nmol m⁻2.s⁻1, whereas promoted uptake, case both woodchips (-1.65 ± 1.03 m⁻2.s⁻1) bark mulch (-0.49 0.16 by second year. Mixed treatments showed greater uptake; for instance, incorporating into led mean uptake (-2.02 1.02 m⁻2.s⁻1), nearly fivefold than controls. While additions reduced water loss increased soil carbon-factors contributing emissions-biochar CO₂ 26.7%-121.1%. Biochar-mediated correlated substrate pH, bulk density, C:N ratio, suggesting enhanced microbial activity release. Overall, findings biochar, combined can serve as effective mitigation strategy, informing climate-smart management landscapes.
