This study developed an mechanical activation enhanced pyrolysis method, using ball-milled macadamia shell@FeCl<sub>3</sub>/urea as a precursor, to prepare iron–nitrogen co-doped biochar (Fe-NMBC) for investigating Cr(VI) adsorption. Characterization reveals that the surface of Fe-NMBC exhibits dense needle-shaped structures, with abundant functional groups (C=O/C-O/C-N) and Fe (II)/Fe (III). It boasts a larger specific surface area and higher O/C and N/C ratios compared to the pristine biochar. The results of the adsorption study demonstrate that Fe-NMBC effectively removes Cr(VI) from solution. The adsorption process was found to the pseudo-second-order kinetic model and Langmuir model, with the saturated adsorption capacity(<em>Q</em><sub>m</sub>) is 40.7 mg·g<sup>−1</sup>. Both monolayer chemical adsorption and diffusion processes are influential in the adsorption process. The adsorption is a spontaneous reaction driven by entropy. The removal mechanism involves the coupled process of adsorption and reduction with surface complexation and reduction reactions serving as the primary driving forces.

A mixture containing 2 wt% CNC and 0.5 mM CTAB produced CO<sub>2</sub> foam with a half-life nearly four times longer than that of CTAB alone at 20 °C and 10 bar. At 50 bar, foam stability extended beyond two weeks, with no observable foam decay and only an 18 % increase in bubble size after 14 days.</div><div>These lifetimes far exceed those reported in prior studies and demonstrate the potential of CNC–CTAB mixtures for applications that demand long-lasting CO<sub>2</sub> foams at elevated pressures. This improved stability is attributed to suppressed drainage and coarsening, resulting from increased bulk viscosity from large CNC-CTAB aggregates, as confirmed through cryo-TEM, confocal microscopy, and rheological analysis.</div></div>","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"154 ","pages":"Pages 397-408"},"PeriodicalIF":5.9,"publicationDate":"2026-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145924188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
