N-DOPED ACTIVATED CARBON OBTAINED FROM PLANT WASTE BY DIFFERENT PRODUCTION METHODS FOR ADSORPTION OF CO2
Аннотация
The pressing need to reduce CO2 emissions and combat climate change has spurred a global commitment towards achieving carbon neutrality. While transitioning to renewable energy is pivotal, the limitations in renewable energy production highlight the necessity for alternative approaches. The focus on capturing and sequestering CO2 has led to the exploration of porous solids, including zeolites, metal-organic frameworks (MOFs), porous organic polymers (POPs), and porous carbons. Porous carbons, with their low cost, widespread availability, large surface area, and ease of design, have garnered attention. However, their reported CO2 adsorption capacities are currently limited. Addressing this constraint, nitrogen doping (N-doping) has proven effective in augmenting surface adsorption sites on porous carbon structures. Various production methods, such as chemical activation with nitrogen-containing compounds, physical methods utilizing nitrogen-containing gases, and hydrothermal methods, have been implemented. Particularly noteworthy is the application of nitrogen-doped activated carbon derived from plant waste, showcasing high surface areas, suitable structures, and significant CO2 adsorption capacities. This positions them as promising candidates for large-scale CO2 capture initiatives, contributing to global efforts in mitigating climate change.
