AI Technical Summary
Existing technologies struggle to achieve a balance between high specific surface area and high nitrogen content in nitrogen-doped hierarchical porous carbon materials under low-cost and sustainable conditions, resulting in low efficiency in CO2 adsorption applications.
Using lignin, a byproduct of the pulp and paper industry, as raw material, and Lewis acid as a mild activator, a high-yield nitrogen and sulfur co-doped hierarchical porous carbon material was prepared through ball milling, carbonization, and activation treatment. The synergistic effect of nitrogen source and Lewis acid improved pore-forming efficiency and specific surface area.
This study achieved a multi-level porous carbon material with high yield, high nitrogen content, and well-developed pore structure, which improved the adsorption capacity and selectivity of CO2, reduced production costs, and enabled the high-value utilization of lignin.
