“…The higher intensity in the low angle region suggests the presence of a large number of micro pores which also substantiated by the N 2 sorption results earlier . The (0 0 2) reflection is generated from the interlayer diffraction of the aromatic carbon and the (1 0 0) reflection results from the in plane 2‐dimensional diffraction of graphitic layers …”

A facile one‐pot synthesis of porous activated biocarbons with a high nitrogen content (NEPBs) through a simple in‐situ self‐assembly of Arundo donax and urea combined with a solid state activation using KOH/ZnCl2 is presented. NEPBs show dominant microporous character and possess a high nitrogen content in the form of pyridinic‐N and pyrrolic‐N and a high specific surface area. The nitrogen content of NEPBs was determined to be in the range of 7.74–19.15%, which was much higher than that of biocarbon derived from non‐activated biomass (1.12%). We also demonstrate that the nitrogen content of NEPBs can easily be tuned by adjusting the impregnation ratios of urea and KOH/ZnCl2. The NEPBs show impressively high CO2 adsorption capacities of 4.8 mmol g−1 at 0 °C/1 bar and 14.1 mmol g−1 at 0 °C/30 bar. A high value of the isosteric heat of adsorption is observed (39 kJ mol−1), confirming the role of nitrogen to enhance the CO2 adsorption capacities through a strong adsorbent‐adsorbate interaction. It is anticipated that the strategy presented here could be extended for the generation of a series of other biomass‐based porous carbon materials with much higher nitrogen contents and controlled textural properties for applications including energy storage and conversion and carbon capture.

“…Nitrogen-containing carbonaceous materials are prepared by two primary methods: the post treatment and in situ method. In the former one, carbonaceous materials are treated with nitrogen containing compounds such as ammonia19, urea and melamine20 to incorporate nitrogen functional groups. It is commonly used to produce various porous carbons, such as carbon nanotubes, graphene, and activated carbons.…”

The preparation of nitrogen-doped activated carbon (NACs) has received significant attention because of their applications in CO2 capture and sequestration (CCS) owing to abundant nitrogen atoms on their surface and controllable pore structures by carefully controlled carbonization. We report high-surface-area porous N-doped activated carbons (NAC) by using soft-template-assisted self-assembly followed by thermal decomposition and KOH activation. The activation process was carried out under different temperature conditions (600–800 °C) using polyimine as precursor. The NAC-800 was found to have a high specific surface area (1900 m2 g−1), a desirable micropore size below 1 nm and, more importantly, a large micropore volume (0.98 cm3 g−1). NAC-800 also exhibits a significant capacity of CO2 capture i.e., over 6. 25 and 4.87 mmol g−1 at 273 K and 298 K respectively at 1.13 bar, which is one of among the highest values reported for porous carbons so far. Moreover, NAC also shows an excellent separation selectivity for CO2 over N2.

“…However, once the tobaccop lant is harvested, its stems and someleaves are generally not used and they are randomly discarded as solid waste or burned off in stacks without treatment; this disturbs the balance of the ecological environment and causes environmental problems.

Solid‐Waste‐Derived Carbon Dioxide‐Capturing Materials

Solid sorbents are considered to be promising materials for carbon dioxide capture. In recent years, many studies have focused on the use of solid waste as carbon dioxide sorbents. The use of waste resources as carbon dioxide sorbents not only leads to the development of relatively low‐cost materials, but also eliminates waste simultaneously. Different types of waste materials from biomass, industrial waste, household waste, and so forth were used as carbon dioxide sorbents with sufficient carbon dioxide capture capacities. Herein, progress on the development of carbon dioxide sorbents produced from waste materials is reviewed and covers key factors, such as the type of waste, preparation method, further modification method, carbon dioxide sorption performance, and kinetics studies. In addition, a new research direction for further study is proposed. It is hoped that this critical review will not merely sum up the major research directions in this field, but also provide significant suggestions for future work.
