Palm kernel shell (PKS) lignin was effectively fractionated and oxidatively depolymerized into valuable phenolic monomers using bimetallic Co–Cu catalysts supported on modified zeolite HY. The catalyst support was optimized by modifying zeolite HY through aluminum doping (Al-HY) and desilication (D_S-HY) to fine-tune its acidity and pore structure. The bimetallic catalysts were synthesized using these modified supports with 10 wt% total metal loading at a Co:Cu ratio of 4:1. Characterization techniques, including BET, XRF, NH₃-TPD, H₂-TPR, XPS, and TEM, confirmed successful metal incorporation and preserved crystallinity, hierarchical porosity, and redox-active metal states. Catalytic oxidative cracking was conducted in a 9:1 isopropanol/water medium with hydrogen peroxide as the oxidant at atmospheric pressure. The implementation of the desilicated zeolite-supported bimetallic catalyst (10 %Co₄-Cu₁/D_S-HY) substantially improved the catalytic reaction, achieving a lignin-derived monomer yield of 37.62 % and 86.75 % biomass conversion. This represents a 9.83 % improvement over the conventional zeolite HY-supported bimetallic catalyst. The enhanced activity is attributed to the synergistic interaction between the Co–Cu redox sites and the tailored acidity and mesoporosity of the modified zeolite support. Furthermore, catalyst reusability tests demonstrated that the optimized catalyst retained over 90 % of its initial activity after four reaction cycles, confirming its stability and potential for industrial applications. The insights from this study are expected to drive progress in lignin-based biorefinery technologies.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 6","pages":"Article 119233"},"PeriodicalIF":7.2,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145048496","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}

Alkali-activated materials (AAMs) have emerged as promising low-carbon alternatives that offer high mechanical performance and reduced environmental impact. However, their widespread adoption is limited by the high cost and environmental risks associated with conventional strong alkali activators. All-solid-waste alkali-activated materials (ASW-AAMs) provide an innovative “waste-treats-waste” strategy through the synergistic substitution of conventional strong alkalis with alkaline industrial byproducts. This approach aligns with principles of resource efficiency and environmental protection. Despite its promise, the development of ASW-AAMs faces several critical challenges, including variability in raw material composition, incomplete understanding of reaction mechanisms, and inadequate long-term performance data. To address these issues in a systematic manner, this review investigates three key research domains, namely, the synergistic optimization of multi-source solid waste co-processing, the mechanisms that govern the regulation of mechanical properties, and the micro-scale elucidation of hydration reaction dynamics. Furthermore, the study emphasizes the indispensable role of molecular dynamics simulations in unraveling atomic-scale reaction mechanisms. It also explores the potential of machine learning-based approaches for predictive modeling. These insights contribute to the establishment of a foundational framework for the industrial implementation of ASW-AAMs. By enabling the transformation of industrial byproducts into high-performance construction materials, ASW-AAMs offer a viable pathway toward decarbonization and the advancement of circular economy objectives in the construction industry.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"13 6","pages":"Article 119204"},"PeriodicalIF":7.2,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145061425","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 modification strategy achieved the synergistic enhancement of “skeleton nitrogen” and “functional group nitrogen”. N₄₀₀-BC/P₁₀ exhibited a high affinity toward Cr(VI). At pH 2, the adsorption capacity of the material progressively increased with the augmentation of nitrogen content. At an initial concentration of 200 mg·L⁻¹, N₄₀₀-BC/P₁₀ exhibited an order-of-magnitude increase for Cr(VI) equilibrium adsorption capacity (340.02 mg·g⁻¹) compared with that of single-nitrogen-source modified counterpart (251.36 mg·g⁻¹). Even in the presence of interfering coexisting anions and cations, N₄₀₀-BC/P₁₀ maintained an adsorption capacity of at least 296.68 mg·g⁻¹ and a removal efficiency of at least 74 %. The adsorption process followed the pseudo-second-order kinetics and the Langmuir isotherm model, indicating that chemical adsorption was the predominant mechanism. XPS analysis revealed that the removal of Cr(VI) by N₄₀₀-BC/P₁₀ followed a coupled mechanism of “adsorption-reduction-stabilization”. Moreover, N₄₀₀-BC/P₁₀ demonstrated excellent practical wastewater treatment capability, highlighting its significant potential for industrial wastewater treatment. The dual-nitrogen-source anchoring strategy proposed in this study provides a new paradigm for the design of biochar-based heavy metal removal materials with high performance, low cost, and low environmental load.

DFT calculations demonstrated that the higher reactivity of HNR was closely related to the stronger affinity between its surface Fe(III) and amino groups of 6PPD. This process led to more vigorous electron transfer, as verified by more environmentally persistent free radicals (EPFRs) formation. Moreover, more reactive oxygen species (ROS) induced by HNR were involved in 6PPD degradation, which significantly drove the oxidation of EPFRs and other intermediate products.

Abiotic aqueous and soil microcosm incubations were conducted to explore the response of N₂O emissions to these materials. Results showed that additions of BC, ZVI, and ZVI/BC lowered N₂O emissions from nitrate-fertilized paddy soils, with mitigation efficiencies of 67.0 %, 36.3 %, and 54.0 %, respectively. Specifically, BC increased soil pH and dissolved organic carbon, which stimulated the growth of N₂O-reducing microorganisms (e.g., <em>Bryobacter</em> and <em>Candidatus_Solibacter</em>) and inhibited the growth of N₂O-producing microorganisms (e.g., <em>Terrabacter</em>, <em>Conexibacter</em>, and <em>Pseudeurotium</em>), thereby increasing the <em>nosZ</em>/(<em>nirK</em> + <em>nirS</em>) ratio and decreasing N₂O emissions. Oppositely, abiotic aqueous experiment indicated that ZVI resulted in the accumulation of nitrite (NO₂⁻-N) and N₂O. However, ZVI converted nitrate nitrogen (NO₃⁻-N) to ammonium nitrogen (NH₄⁺-N) via abiotic reduction, decreasing denitrification substrate and N₂O emissions. Further, BC as a support inhibited the chemical reaction of ZVI with NO₃⁻-N to produce NO₂⁻-N and N₂O and improved the mitigation of N₂O emissions by ZVI via inhibiting NO₃⁻-N reduction.
