“…Figure 7 presents the N 2 adsorption and desorption isotherms and pore size distribution curves obtained for the NPPCs. According to the IUPAC classification, the N 2 adsorption-desorption isotherms for the NPPCs exhibited characteristic type I behavior, indicating that a porous carbon material was dominated by micropores [48,49]. When the relative pressure (P/P 0 ) approached 0, the observed vertical linear region could be attributed to the monolayer adsorption of N 2 in the microporous.…”

The adsorption and enrichment of greenhouse gases on biomass porous carbon is a promising approach. Herein, a simple type of nitrogen and phosphorus co-doped biomass porous carbon (NPPC), which was derived from fast-growing eucalyptus bark, was reported via one-step method of carbonization and activation, and the nitrous oxide (N2O) adsorption performance and the adsorption mechanism of the NPPCs were also investigated. The results showed that NPPC-800-2 demonstrated a high specific surface area (1038.48 m2∙g−1), abundant micropores (0.31 cm3∙g−1), and enriched content of N and P (4.17 wt.% and 0.62 wt.%), which also exhibited a high N2O adsorption capacity of 0.839 mmol∙g−1. Moreover, the addition of N enhanced the surface polarity of carbon, thereby altering its pore structure. And P doping induced changes in the structural orientation of carbon, resulting in an increased presence of N-P functional groups. This finding reveals that the eucalyptus bark-based N and P co-doped porous carbon shows great potential for wide applications in N2O capture and provides effective guidance for the design and development of waste biomass adsorbent.

“…In the context of the global production of activated carbons from agro‐industrial residues, the choice of this precursor becomes strategically relevant. According to the findings of Serafin and Dziejarski , [33] most biomass precursors essential for activated carbon synthesis originate from various economic sectors. Walnut shell is a vital raw material, considering its widespread availability worldwide.…”

In a single step, nitrogen‐doped activated carbons have been synthesized using walnut shells and urea as precursors by chemical activation with K2CO3. The textural and elemental properties such as surface area, micropore volume, nitrogen content, and yield were optimized in a multivariable way using a central composite design of experiments 23, varying the urea‐nutshell ratio, K2CO3 ratio, and activation temperature. Activated carbon doped with the highest nitrogen presented a surface area of 895 m2 g−1, a micropore volume of 0.22 cm3 g−1, and a nitrogen content of 4.11 %. Furthermore, the yield of 13.85 % at urea impregnation ratio 1.56 gUrea gNutshell−1, activating agent ratio 1.4 gK2CO3 gCarbon−1, and temperature of 591 °C, being the temperature and the urea impregnation ratio the significant variables in the responses evaluated. The best‐activated carbon doped with nitrogen presented a CO2 adsorption capacity of 2.78 mol kg−1, reversible adsorption‐desorption, and selectivity against nitrogen of 33.2 molCO2/molN2, superior to a commercial activated carbon with similar textural properties at the same experimental conditions and being in the order of magnitude as activated carbons synthesized under similar conditions.

Inexpensive porous activated biocarbons were prepared from biomass and agriculture waste following the method of thermal and hydrothermal carbonization and activation with superheated water vapor. The activated biocarbons were characterized by nitrogen adsorption–desorption at 77 K, SEM, XRD, Raman spectrometry, FTIR spectroscopy, determination of particle size, and elemental composition by XRF. The specific surface area was in the range of 240–709 m 2 /g, and the total pore volume was from 0.12 to 0.43 cm 3 /g. The percentage of microporosity in activated biocarbons was 89–92%. These activated biocarbons have been used for CO 2 and heavy metal sorption. Activated biocarbons based on pine cones and birch prepared by thermal carbonization and activation with superheated water vapor had the highest ability to capture CO 2 and amounted to 6.43 and 6.00 mmol/g at 273 K, as well as 4.57 and 4.22 mmol/g at 298 K, respectively. The best activated biocarbon was characterized by unchanged stability after 30 adsorption and desorption cycles. It was proved that the adsorption of CO 2 depends on narrow micropores (<1 nm). Activated biocarbons have also been analyzed as effective adsorbents for removing Cu 2+ , Zn 2+ , Fe 2+ , Ni 2+ , Co 2+ , and Pb 2+ ions from aqueous solutions. Activated biocarbons are effective adsorbents for the removal of lead and zinc ions from aqueous solutions.
