However, despite the widespread use of copper-based systems for methanol synthesis in recent decades, the chemical state of the active Cu species remains controversial. In this study, various Cu/ZnO/SBA-15 catalysts possessing different interfacial structures were engineered by atomic layer deposition (ALD). The optimized Cu/50c-ZnO/SBA-15 afforded the highest mass-specific methanol formation rate of 211.7 g<sub>MeOH</sub>·kg<sub>cat</sub><sup>−1</sup>·h<sup>−1</sup> under the conditions of 250 °C and 3.0 MPa. In-depth characterizations indicated that the electronic state of Cu could be modulated by engineering the interfacial structures of the Cu/ZnO series catalysts, and the Cu cation sites (Cu<sup>δ+</sup> and Cu<sup>+</sup>) are the active centers for methanol synthesis reaction rather than the Cu<sup>0</sup> sites. Mechanistic analysis demonstrated that HCO<sub>3</sub>* and CO<sub>3</sub>* were slowly transformed to HCOO* and further hydrogenated to methanol following the formate-methoxy intermediate route.

The results indicated that a high C/N ratio was favorable for cell growth, whereas a low C/N ratio was advantageous for protein synthesis.

In this review, we have summarized the current understanding of macroalgal microbiomes, highlighting critically underexplored microbial components, such as overlooked taxa, host specificity, and the environmental factors influencing microbiome composition, which hinder the development of effective microbiome engineering strategies. We critically evaluate existing microbiome manipulation approaches and their applications in enhancing macroalgal growth, resilience, carbon fixation, and biomass yield and assess their potential for improving macroalgal carbon sequestration. Finally, we propose a holistic framework that integrates multi-omics and metabolic modeling, microbial functional and environmental compatibility, high-throughput rapid isolation, and <em>in vivo</em> validation to bridge critical knowledge gaps and unlock the full potential of macroalgal microbiome engineering for sustainable, large-scale macroalgal farming.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"3 1","pages":"Pages 63-73"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724857","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}
