This review provides a comprehensive overview of precursor types and synthesis strategies, including pyrolysis, chemical activation, template-assisted, hydrothermal, plasma, and microwave-assisted methods, and examines the effects of these approaches on the structural and surface properties of the materials. The role of nitrogen doping in enhancing CO₂ adsorption capacity, selectivity, and interaction mechanisms is critically assessed. Emphasis is placed on identifying active sites and understanding the contributions of pyridinic, pyrrolic, and graphitic nitrogen under various conditions. The discussion includes stability, regeneration behaviour, and comparisons with conventional adsorbents to assess their practical applicability. The review further integrates computational and data-driven approaches. Density functional theory studies offer atomistic insights into potential energy of CO₂ surface interactions, while machine learning (ML) models facilitate the mapping of structure performance relationships and the prediction of adsorption capacity based by analysing key input such as micropore volume, Brunauer–Emmett–Teller surface area, and nitrogen speciation. Key challenges are also addressed, including lack of data, inconsistent datasets from the literature, and limited experimental validation of ML predictions. Despite significant progress, challenges remain in scaling synthesis methods, improving long-term stability under realistic conditions, and optimising nitrogen functionalities.

Under optimal conditions (3 bar, pH 7, and polymer concentration of 1000 ppm), copper rejection reached 96% with PEI and 95% with PSS, while PAA exhibited lower performance due to increased membrane fouling. When applied to real industrial wastewater, copper removal efficiencies of approximately 91% and 87% were achieved with PEI and PSS, respectively. Significant reductions in suspended solids, turbidity and conductivity were also observed, with moderate chemical oxygen demand removal.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> CONCLUSION</h3>\u0000 \u0000 <p>The PEUF process demonstrates high efficiency for copper removal and enables compliance with the Tunisian discharge standard NT 106-02. These results highlight PEUF as a promising and effective technique for industrial wastewater treatment and reuse. © 2026 Society of Chemical Industry (SCI).</p>\u0000 </section>\u0000 </div>","PeriodicalId":15335,"journal":{"name":"Journal of chemical technology and biotechnology","volume":"101 9","pages":"1790-1800"},"PeriodicalIF":2.7,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148662667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
