Here, this study systematically decouples these roles by comparing pristine biochars from four feedstocks, their acid‑demineralized counterparts, and the demineralized biochar subsequently reloaded with K, Na, Mg, or Ca. Using multi-technique characterization (XPS, FTIR, Raman, XRD, SEM‑EDS, zeta potential measurements) and mediated electrochemical analysis, this study confirms that endogenous AAEMs act as structural dopants, catalyzing the formation of oxygen‑containing groups (C-O and carboxyl) and defect sites (high I_D/I_G), resulting in an intrinsically negative surface charge and a high electron donating capacity (EDC up to 1.25<!--> <!-->mmol e^-·g^-1 in CMBC). Acid demineralization removes AAEMs, drastically lowering EDC by 85–90% and shifting the surface charge from permanent to pH‑dependent. Reloading AAEMs creates cation-specific effects, and monovalent K⁺ and Na⁺ mainly form soluble salts and enhance EDC modestly through electrostatic screening and cation‑π interactions, while divalent Mg²⁺ and Ca²⁺, especially Ca²⁺, re‑establish oxygen‑rich surfaces (O/C up to 0.48) and induce new defects, achieving the highest EDC recovery among all loaded biochars (0.29<!--> <!-->mmol e^-·g^-1). These findings demonstrate that endogenous AAEMs build an effective electron reservoir, while exogenous AAEMs act as tunable surface modifiers, providing a mechanistic framework for designing biochars with predictable electrochemical properties.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"14 5","pages":"Article 123460"},"PeriodicalIF":7.2,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148193455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By combining lean vapor compression (LVC), an electric heat pump (HP), turbo-generation, and conventional solvent-based post-combustion CCS, this design tackles key bottlenecks in marine carbon capture: poor fuel adaptability and low energy self-sufficiency. The system is evaluated under LNG and HFO modes and compared with HP+CCS and standalone CCS using a 5E (energy, exergy, economic, environmental, energy level) analysis. The influences of flue gas temperature (<span><math><msub><mrow><mi>T</mi></mrow><mrow><mi>F</mi></mrow></msub></math></span>), flow rate (<span><math><msub><mrow><mi>m</mi></mrow><mrow><mi>F</mi></mrow></msub></math></span>), and liquid‑to‑gas ratio (L/G) are also analyzed across fuel conditions. Under design conditions, the LVC+HP+CCS configuration outperforms both HP+CCS and standalone CCS systems. The system achieves energy efficiencies of 26.74% _(LNG) and 22.31% _(HFO), with improvements of 7.11% and 3.02% compared with HP+CCS.

Despite its foundational role, the hydroxyl radical is denoted in multiple, often inconsistent forms across the literature. As these representations propagate across chemistry, environmental engineering, and mechanistic and photochemical modeling frameworks, they increasingly obscure structural meaning and complicate mechanistic interpretation. This is not a cosmetic issue. In aqueous systems where multiple radical families coexist (HO^•, SO₄^•−, CO₃^•−, Cl^•/Cl₂^•− and related chemical species), dot placement encodes the location of the unpaired electron and implicitly defines the presumed site of reactivity. Ambiguous notation therefore propagates into mechanistic schemes, kinetic interpretations, reaction databases, modelling frameworks, and education. Here, we explain the scientific and IUPAC basis for writing the hydroxyl radical as HO^•, clarify a persistent typographic confusion between the radical dot and the hydrate separator dot, and propose a practical pathway for standardizing radical notation across water research. Correct and uniform notation is a step toward greater mechanistic clarity, reproducibility, and interoperability in aqueous radical chemistry.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"14 3","pages":"Article 122281"},"PeriodicalIF":7.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148184408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically elucidates the deactivation mechanism of industrial waste vanadium-titanium-based catalytic filters and proposes an efficient thermal regeneration method by ammonium sulfate. The catalytic performance tests of poisoned industrial catalytic filter and simulation poisoning/regeneration samples demonstrate that the catalyst deactivation is caused by Ca(OH)₂ rather than thermal sintering or ammonium sulfate deposition and the Ca(OH)₂ poisoned catalytic filter can be easily/effectively regenerated by thermal treatment with ammonium sulfate. Multiple structural characterizations reveal that the catalytic filter poisoned by calcium originates from the formation of inert CaV₂O₆ phases between Ca²⁺ and active VO_<em>x</em> species during the long-term use under high application temperature, and SO₄^2- can preferentially react with CaV₂O₆ to form thermodynamically stable CaSO₄ and release the active VO_<em>x</em> sites with recovered catalytic ability (e.g., easy oxidation reduction cycle of V⁵⁺/V⁴⁺, sufficient surface acidity and active oxygen species). <em>In situ</em> FTIR spectra analysis further indicates toxic calcium species severely suppresses NH₃ adsorption, but thermal regeneration by (NH₄)₂SO₄ can restore the adsorption capacity and enhance the adsorption rate of NH₃, accounting for the recovered catalytic performance of the regenerated catalytic filter.
