Several studies have shown that adsorption based on carbonaceous materials and their composites is an efficient technique for the remediation of these pollutants. This review extensively addresses the recent advances in preparation, characterization, and application of the abovementioned adsorbents against a variety of phenolic pollutants. The carbonaceous materials, including activated carbon, biochar, and carbon nanotubes, as well as their composites with magnetics, clays, chitosan, zeolites, etc., exhibited favorable properties in terms of porosity and functionality. Activated carbon was the most frequently used adsorbent, with a higher performance against phenolic pollutants relative to biochar and carbon nanotubes. Moreover, carbonaceous material composites mostly showed higher adsorption performance than their raw forms. Phenol and its derivatives, such as p-nitrophenol, p-chlorophenol, 2,4-dichlorophenol, p-cresol or p-methylphenol, and resorcinol or 3-hydroxyphenol, were the most widely tested pollutants. The results of isotherm, kinetic, thermodynamic, mechanism, and regeneration studies were discussed. Pseudo-second order and Langmuir/Freundlich equations well represented most of the adsorption data. The dependence of adsorbent performance on pH, adsorbent dose, temperature, contact time, and inlet pollutant amount was also considered. Important findings, limitations, and future ideas are finally displayed.</div></div>","PeriodicalId":345,"journal":{"name":"Journal of Analytical and Applied Pyrolysis","volume":"195 ","pages":"Article 107629"},"PeriodicalIF":6.2,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146074509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of dual K/F doping on the structural evolution, surface chemistry, and electrochemical behavior of pistachio shell-derived activated carbon (PSAC) was systematically investigated. XRD and Raman analyses revealed partial graphitization accompanied by increased defect density after K/F incorporation, as evidenced by the appearance of a broadened (002) diffraction peak at ∼26° in the XRD pattern and an increased Raman <em>I</em>D/<em>IG</em> ratio compared to pristine PSAC, while FTIR and XPS confirmed significant modification of surface functional groups and successful introduction of K, F, and oxygen-containing species. Textural characterization demonstrated that K/F doping induced pore widening and the development of a hierarchical pore structure, with a decrease in BET surface area from 483 to 383 m² g⁻¹ accompanied by a substantial increase in average pore radius from 1.65 to 3.94 nm. Electron microscopy analyses showed that K/F modification resulted in rougher, more heterogeneous surfaces and a more uniform layered morphology at the nanoscale. Electrochemical evaluation in aqueous electrolytes revealed that K/F-doped PSAC exhibited significantly enhanced charge-transfer kinetics, lower interfacial resistance, and improved ion diffusion compared to pristine PSAC. The modified electrode delivered a high specific capacitance of 188 F g⁻¹ at 0.5 A g⁻¹ and maintained excellent rate capability and cycling stability, retaining 88.2 % of its initial capacitance after 10 000 charge–discharge cycles. Kinetic analysis indicated that K/F doping strengthened diffusion-controlled charge storage without shifting the mechanism toward purely capacitive behavior.

To elucidate the low-temperature oxidation characteristics of biomass coupled with coal and establish a hierarchical early-warning method, this study employs systematic investigations using thermogravimetric analysis, thermal analysis kinetics, and programmed temperature experiments. Results indicate that biomass blending lowers the characteristic temperature of samples and increases mass loss rates. The presence of alkali metal ions significantly reduces the activation energy of oxidation reactions, accelerating coal oxidation. Kinetic analysis reveals that both activation energy and pre-exponential factor increase overall as biomass content decreases, indicating the blending ratio regulates the reaction energy barrier. Programmed temperature experiments further revealed that as the biomass proportion increases, the generation of typical indicator gases such as CO and CO₂ in the low-temperature oxidation process of biomass-coupled coal exhibits exponential growth. The release temperature occurs significantly earlier than that of raw coal, and the release rate intensifies. Based on this, key gas indicators were optimized to establish a three-tiered early warning system, Level I, II, and III, for biomass-coupled coal fuels.
