In the context of climate change, advanced methods for carbon dioxide (CO₂) capture are needed. Organic biomass from living organisms, e.g., plants, is known to capture CO₂ by photosynthetic assimilation, yet physical adsorption of CO₂ onto biomass is poorly known. Here, we used molecular modeling of various biomass components to estimate the efficiency of CO₂ capture by biomass. Results show that that CO₂ adsorption is controlled by a ‘CO₂–water–biomass’ network involving the sharing of common water molecules. Water interacts with CO₂ through CO–OH bonds. A single water molecule participates in water–biomass interaction through either H–OH or HO–H bonds. CO₂ adsorption is controlled by biomass moisture. Data show that 5–56 g of CO₂ could be adsorbed per gram of biomass at 230–310 K and atmospheric pressure.

在气候变化的背景下，（CO二氧化碳先进方法₂需要）捕获。已知来自生物等生物的有机生物质通过光合同化来捕获CO ₂，但对CO ₂在生物质上的物理吸附却知之甚少。在这里，我们使用了各种生物质组分的分子模型来估计生物质捕获CO ₂的效率。结果表明，CO _2的吸附受“ CO _2-水-生物质”网络的控制，该网络涉及共同的水分子的共享。水与CO ₂相互作用通过CO-OH键。一个水分子通过H-OH或HO-H键参与水与生物质的相互作用。CO ₂吸附受生物质水分控制。数据显示，在230-310 K和大气压下，每克生物量可吸附5-56 g CO ₂。
