The immobilized enzyme was characterized using FTIR, XRD, SEM, and TGA, and the maximum adsorption capacity was found to be 672.1 ± 5.5 mg g⁻¹ at 40 °C. Adsorption equilibrium data indicated that alcalase physically adsorbed onto the ZIF-L, with the isotherm well described by the Freundlich model. The adsorption kinetics aligned best with the pseudo-first order model, suggesting that both film and intraparticle diffusion were significant. The hydrolytic activity of the immobilized A@ZIF-L was initially tested using BSA as a substrate. A diffusion-reaction model was developed and numerically solved to describe the reaction, with results confirming the presence of mass transfer limitations in the early stages of hydrolysis. The stability of the immobilized enzyme was demonstrated by retaining over 90 % of its initial activity after being stored at 4 °C for 70 days. Furthermore, the immobilized A@ZIF-L was used to hydrolyze protein extracts derived from <em>Scenedesmus sp</em>. microalgae. The bioactivity of the resulting protein hydrolysates was characterized, showing a total phenolic content of 29.1 ± 0.6 mg GAE g⁻¹ and a radical scavenging activity of 82.75 ± 2.20 %. These findings highlight the potential of Alcalase-based biocatalysts for applications in the food industry.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 2","pages":"Article 100091"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144713589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Potassium activation is a traditional and effective way to prepare oxygen-rich porous carbons. Efficient potassium activation is the key to develop high-performance oxygen-rich porous carbon cathodes. Herein, the alkali lignin, extracted from eucalyptus wood by geopolymer-assisted low-alkali pretreatment, is used to prepare oxygen-rich lignin-derived porous carbons (OLPCs) through KOH activation and K₂CO₃ activation at 700–900 °C. KOH activation constructs a hierarchical micro-mesoporous structure, while K₂CO₃ activation constructs a microporous structure. Furthermore, K₂CO₃ activation could more efficiently construct active oxygen (C = O) species than KOH activation. The OLPCs prepared by KOH/K₂CO₃ activations at 800 °C show the highest microporosity (78.4/87.7 %) and C = O content (5.3/8.0 at.%). Due to that C = O and micropore adsorb zinc ions, the OLPCs prepared by K₂CO₃ activation at 800 °C with higher C = O content and microporosity deliver superior capacitive performance (256 F g^-1 at 0.1 A g^-1) than that by KOH activation at 800 °C (224 F g^-1 at 0.1 A g^-1), and excellent cycling stability.

The activated carbon is prepared by using H₃PO₄ as a chemical activation agent, and then calcining the obtained product at 500 °C for different controlled atmospheres under (i) air (AC-Atm), (ii) vacuum (AC-Vac), and (iii) argon (AC-Arg).

However, utilization of CO-rich or H₂-rich gas of strong reducibility as reducing agent for magnetization roasting would lead to over-reduction of Fe₂O₃ in the ore to non-magnetic FeO, which makes the magnetism of the roasted ore be lower than its maximum, and hence leads to a lower iron recovery than expected. To explore the possibility of using CH₄ as reducing agent for controllable reduction of Fe₂O₃ in iron ores to selectively forming magnetic Fe₃O₄, i.e., for maximizing the magnetism of the reduced ore for efficient iron separation and recovery, a series of fluidized bed reduction tests in CH₄ were carried out on two iron ores of 55 % and 33 % iron at different temperatures for different periods of time, and the resultant reduced ore particles were magnetically separated for recovery of iron concentrate. XRD and ICP analyses were performed on all recovered iron concentrates to identify the crystal forms of their iron species and to quantify their iron contents. The results have shown that the controllable reduction by CH₄ of Fe₂O₃ in the iron ores to strongly magnetic Fe₃O₄ can be realized by controlling the reduction temperature and time condition applied. The resultant concentrates can be fully recovered by magnetic separation in a weak magnetic field of 60 kA/m to attain a maximum iron recovery of 98 % for the high-grade ore and that of 65 % for the low-grade ore. Besides, the results have also shown that the most critical factor affecting the controllability of the ore reduction process and the selectivity to the generation of magnetic Fe₃O₄-containing particles is the reduction temperature, and that the upper temperature threshold for the controllable reduction and selective generation of strongly magnetic iron concentrate is about 650℃.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 1","pages":"Article 100078"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141698256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biochar has emerged as an eco-efficient catalyst support material. In this study, biochar derived from corn stover (BCS) was first used as a metal catalyst support material for xylose hydrogenation into xylitol. The catalyst was prepared by carbonizing corn stover (CS), impregnating the resulting biochar with metal, and reducing the metal-impregnated BCS. The catalyst characteristics were comprehensively explored. The Ru/BCS catalyst was employed in xylose conversion to xylitol at different process temperatures (100 – 160 °C), retention times (3 – 12 h), H₂ pressures (2 – 5 MPa), and Ru contents (1 – 5 %). The highest xylitol yield (87.0 wt.%) and selectivity (91.6 %) were derived at 120 °C for 6 h under 4 MPa H₂ using 5 % Ru. Interestingly, the Ru/BCS catalyst showed high stability under the promising process condition. Additionally, xylitol production from hydrolysates enriched with CS xylose was subsequently explored. On the other hand, the catalyst characterization results revealed that the superior catalytic efficiency of 5Ru/BCS was mainly due to the metal nanoparticles embedded in the biochar. Additionally, BCS proved to be an outstanding support material for a bimetallic hydrogenation catalyst (Ru-Ni/BCS). Therefore, these results indicate that BCS can be a competitive support material for metal hydrogenation catalysts, enhancing environmental friendliness and potentially being employed in industrial-scale xylitol production.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 1","pages":"Article 100083"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748519","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
