This novel nitrogen-rich sorbent achieves a CO2 uptake capacity of 3.11 mmol g−1, nearly three times that of conventional sorbents.
Under accelerated ageing at 85°C, the new sorbent retains over 75% of its capacity after seven days, outperforming traditional materials.
The synthesis method is environmentally friendly, enabling rapid production in just 10 minutes under ambient conditions.
This advancement addresses major challenges in direct air capture, paving the way for scalable CO2 removal technologies.
