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), H<sub>2</sub> 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 H<sub>2</sub> 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}

This comprehensive review explores the evolving landscape of unconventional oil resources, focusing on the environmental and economic implications of bitumen partial upgrading technologies, particularly within the Canadian context. With over 55 % of the world's oil reserves comprising of unconventional oil, which includes extra-heavy oil and oil sand bitumen, there is a growing trend to shift from traditional oil sources to these abundant yet under-utilized reserves. This review delves into the challenges and advancements in bitumen partial upgrading, highlighting the latest technologies in thermal cracking, hydrocracking, catalytic cracking, and innovative methods like surfactant integration, cavitation, microwave, and plasma-assisted upgrading. It also discusses the environmental implications and economic feasibility of these technologies, emphasizing the necessity for sustainable and cost-effective solutions at petroleum field sites. Furthermore, the report introduces the transformative concept of Bitumen Beyond Combustion (BBC), which explores the non-combustion uses of bitumen and its asphaltene fraction in manufacturing high-value carbon-based products. These novel approaches align with global sustainability goals, offering the potential for significant reductions in greenhouse gas emissions and new routes to diversify the economic applications of bitumen. The review then concludes with an assessment of current challenges and future research directions, advocating for a balanced approach that harmonizes technological innovation, environmental stewardship, and economic viability in the field of bitumen upgrading.</div></div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"4 1","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748520","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}

Subsequently, <em>C. elegans</em> was cultivated on tailor-made semi-defined commercial substrates, resembling hydrolysates containing carbohydrates found in mushroom stalks, under both nitrogen-excess and nitrogen-limited conditions, and resembling that of hydrolysates of roots, under nitrogen-excess conditions. Based on the results, under nitrogen-excess conditions, in the case of media resembling stalks hydrolysates, higher production values for biomass, PUFAs, and GLA were observed (20.3 g/L, 1906 mg/L, 668 mg/L), accompanied by high productivity values due to short cultivation periods, while under nitrogen limitation, high lipid accumulation (lipid in dry cell weight =48%, w/w) was presented, and lipids rich in oleic acid were produced. Finally, the fungus was cultivated on a medium derived from hot water-extraction applied to mushroom stalks, enriched with organic nitrogen sources.

The conversion of toluene into higher value chemicals (benzyl alcohol, benzaldehyde, and benzoic acid, etc.) using sunlight is a very promising means. To achieve the full conversion and utilization of toluene, it is necessary to construct photocatalysts with high conversion and selectivity while synergistically optimizing the optimal reaction environment to significantly affect the photoconversion of toluene. High-performance photocatalysts not only widely absorb sunlight, but also have abundant active sites and generation of free radicals, which can promote the chemical bonds cleavage of toluene, thus greatly increasing the yield of higher-valued products. In addition, the type of photocatalyst and the modification strategy would influence the selectivity of toluene photo-conversion. Therefore, it makes sense that this review presents the reaction mechanism and the influence of reaction factors for the (mainly) photo-oxidation of toluene, a thorough analysis and prediction of the reaction mechanism by theoretical calculations, and the toluene oxidation by different photocatalysts (in particular halogen-containing perovskite materials) to yield specific products, as well as photocatalysts’ modifications.
