Solubility trapping is a key mechanism in geological carbon sequestration (GCS), yet CO2 solubility in water-filled nanopores often deviates markedly from bulk behavior. We hypothesize that variations in CO2 solubility within silica nanopores originate from differences in interfacial water structure that are controlled by surface chemistry. In particular, specific Si-OH arrangements on Q2, Q3, and Q4 silica surfaces (defined by the number of Si atoms bonded through oxygen to a central Si atom) modulate hydrogen-bonding (HB) environments and adsorptive volumes that regulate CO2-water-solid interactions. We conducted molecular dynamics simulations of water-saturated Q2, Q3, and Q4 silica confinements under representative GCS conditions. Interfacial density profiles, HB distributions, and CO2 spatial probability maps were analyzed to quantify fluid-solid interactions and to evaluate CO2 solubility relative to bulk water. Hydrophilic Q3 surfaces exhibit enhanced CO2 solubility compared to the bulk liquid, arising from CO2-water co-adsorption facilitated by a dense interfacial HB network. Hydrophobic Q4 confinements, by contrast, show pronounced over-solubility dominated by strong direct CO2 adsorption within enlarged low-HB regions. Q2 surfaces display intermediate behavior reflecting mixed hydrophilic-hydrophobic character. We introduce two mechanistic descriptors, adsorptive volume and HB site density. High HB site density promotes hydrophilicity and co-adsorption, whereas large adsorptive volume favors direct CO2 adsorption and over-solubility. Overall, these results demonstrate that CO2 solubility in silica nanopores is jointly governed by interfacial water structure and surface chemistry. The findings provide molecular-scale insights into solubility trapping in silica-rich formations and inform the design of engineered materials for CO2 capture and storage.

The development of green, high-efficiency biocides is critical for the effective control of microbial biofilms in water treatment processes. In this study, lignin nanoparticles (NPs), with an average size of around 30 nm, were synthesized via a 'green' process and applied as biocides. A gravity-driven ultrafiltration membrane system was employed to investigate their effects on biofilm composition. The results showed that when the dosage of lignin NPs was only 1 mg C/L, the abundances of bacteria and fungi in the membrane biofilms were reduced by >98%, and the total protein and polysaccharide contents in the extracellular polymeric substance (EPS) decreased significantly, demonstrating remarkable advantages. The core antimicrobial mechanism involves two synergistic effects: (1) Hydrogen bonds are formed between the hydrophilic carboxyl groups on lignin nanoparticles (NPs) and EPS-components of microbial cell walls, directly inhibiting microbial viability and proliferation while reducing EPS secretion; (2) Lignin NPs are oxidized to aromatic derivatives, with benzene rings converted into hydroxyl‑enriched phenolic structures, and the concurrent elevation of carbonyl (C=O) groups in extracellular proteins enhances hydrophobicity. The oxidized lignin NPs then amplify antimicrobial efficacy via hydrophobic associations with these modified aromatic compounds and proteins. This work provides a novel approach and new insights into the rational design of green biocides and the regulation of membrane biofilms.
