In the solvolytic liquefaction reaction of biomass, biopolymers are produced by bond-breakage in the complex lignocellulosic composition using the appropriate solvent and functionalizing the related fragments under mild conditions. The utilization of these bio-polyols as carbon sources has enhanced the conspicuous relevance in the handling of agroforestry by-products as an alternative to fossil fuel-based sources, taking into account the terms sustainability and environmental impact. In this study, a green and inexpensive method based on the resinification and subsequent foaming of bio-polyols produced by solvolytic liquefaction of the tree bark was adopted to synthesize carbon foams with a well-developed hierarchical porous structure. The novelty of this study to brighten the studies in the literature was to examine the characteristics of biomass-based carbon foams produced by adding two types of non-ionic surfactants (P123 and PEG3000) into the synthesis medium at different surfactant/biomass ratios (0.15 and 0.20 w/w). This study comprises a promising technique that promotes self-foaming in the existence of non-ionic surfactants to produce reticulated carbon foams from forest industry wastes with porous graphitic structure, high surface area (up to 758 m²/g), and controlled pore size distribution in the micro-pore region (d_p<2 nm).

在生物质的溶剂化液化反应中，生物聚合物是通过使用适当的溶剂在复杂的木质纤维素组合物中破坏键并在温和的条件下功能化相关片段而生产的。这些生物多元醇用作碳源，在考虑到可持续性和环境影响这一术语的基础上，增强了农用农副产品作为化石燃料源替代品的重要性。在这项研究中，基于树皮的溶剂化液化产生的生物多元醇的树脂化和随后起泡，采用一种绿色且廉价的方法来合成具有发达的分级多孔结构的碳泡沫。这项研究的新颖性是为了启发文献研究，它是研究通过将两种类型的非离子表面活性剂（P123和PEG3000）以不同的表面活性剂/生物质比（0.15）添加到合成介质中而生产的基于生物质的碳泡沫的特性。和0.20 w / w）。这项研究包括一项有前途的技术，该技术可在存在非离子表面活性剂的情况下促进自发泡，从而从具有多孔石墨结构，高表面积（最大758 m）的林业废弃物中产生网状碳泡沫。² / g），并控制了微孔区域的孔径分布（d _p <2 nm）。
