“…The textural parameters of the obtained biochars were discussed in detail in our previous work [24] . Briefly: the biochars are characterized by a poorly developed specific surface area ranging from 2.2 to 3.1 m 2 /g and total pore volume varying between 0.005–0.007 cm 3 /g, which can limit their adsorption capacity.…”

“…The gravimetric methods described in our previous paper were used for this purpose. [24] The surface charge density (σ 0 ) of the obtained biochars was determined applying the potentiometric titration method. For this purpose the 0.5 g of material was added to the 0.05 dm 3 of NaCl solution with concentration of 0.001 mol/dm 3 (supporting electrolyte).…”

However, it should be noted that all of the obtained adsorbents are classified as mesoporous (mean pore size in the range of 8.4-10.6 nm), which is a desirable property for the adsorption of large polymer macromolecules.…”

The nettle, sage, mint and lemon balm herbs were used for biochars preparation. The physicochemical parameters of obtained materials were related to the lignocellulose composition of the precursors. It has been proved that the content of mineral substance has a significant influence on development of surface area, whereas the amount of hemicellulose affects the content of surface functional groups. It has been also shown that the obtained biochars are characterized by great energy parameters. The higher heating values (HHV) of the carbonaceous materials are comparable to the typical energy sources. The greatest HHV value (20.36 MJ/kg) was characteristic for the biochar obtained by pyrolysis of the lemon balm. In addition, the biochars were used for ionic polymers adsorption from one‐ and two‐components solutions. Despite the adsorbed amounts of macromolecules are not great is has been proved that polyethylenimine and polyacrylic acid have positive influence on their mutual adsorption.

“…To further enhance the performance and value of LBC, activation or modification treatments are often applied, increasing its pore structure and surface functional groups to improve its adsorption capacity and reactivity. This method can produce biomass-based activated carbon with a high specific surface area and mechanical strength [ 25 , 26 ].…”

With the rapid growth in the global population and the accelerating pace of urbanization, researching and developing novel strategies for biomass utilization is significant due to its potential for use in renewable energy, climate change mitigation, waste management, and sustainable agriculture. In this environmental context, this review discusses the recent advances in biomass conversion technologies for biochar production, including the first carbonization process and the subsequent activation methods of the biochar derived from lignocellulosic biomass (LBC). Parallel to this, this review deals with other essential parameters in biochar production, such as feedstock types, reaction environments, and operating conditions in the pyrolysis process, to determine the production and composition of LBC. Moreover, the wide-ranging applications of LBC in areas such as adsorption, catalysts, and energy storage are discussed, offering sustainable and environmentally friendly alternatives while reducing reliance on traditional energy sources and mineral resources, thereby providing practical solutions to environmental and energy challenges. Overall, this review not only provides a comprehensive comparative analysis of different LBC preparation methods, but also facilitates a deeper understanding of the advantages and limitations of these methodologies when it comes to developing high-value materials for sustainable applications.
