Macroalgal carbon sequestration primarily refers to the long-term storage of macroalgae-derived organic carbon in the ocean. However, calcium carbonate (CaCO₃) formation is frequently observed in non-calcifying macroalgal environments, suggesting the existence of an overlooked inorganic carbon process in macroalgal ecosystems. Here, we introduce multiple pathways that may drive CaCO₃ formation in macroalgal ecosystems. These include the effects of macroalgal photosynthesis and carbon-concentrating mechanisms on the seawater carbonate system, the role of phycosphere interfacial properties in facilitating CaCO₃ nucleation, and the macroalgae-bacteria synergy that promotes CaCO₃ formation. We identified several current knowledge gaps—the unclear carbon sequestration or source effect of CaCO₃ formation in macroalgal ecosystems and the stability of CaCO₃ minerals in macroalgal ecosystems—that require further investigation. This review advances the understanding of macroalgal carbon cycling beyond organic pathways and emphasizes the importance of a comprehensive assessment of macroalgal carbon sequestration, including that of inorganic carbon.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"4 3","pages":"Pages 285-292"},"PeriodicalIF":14.2,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149028878","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}

We first profiled the gut transcriptome of <em>Z. morio</em> larvae to uncover this mechanism, and identified a host-encoded, midgut-specific lytic polysaccharide monooxygenase gene, <em>ZmLPMO15-2,</em> which was significantly upregulated in response to straw feeding. Functional characterization confirmed that ZmLPMO15-2 oxidatively cleaves cellulose and synergistically boosts its glycosyl hydrolase activity. Its functional role in the degradation of straw cellulose by <em>Z. morio</em> was further validated by RNAi knockdown and subsequent rescue <em>via</em> bacterial replenishment. Concurrently, the gut microbiota of straw-fed larvae shifted significantly, becoming enriched for <em>Kluyvera</em>. Using culturomics, whole-genome sequencing, and structural characterization, we isolated a novel lignin-degrading bacterial strain, <em>Kluyvera</em> sp. Zm8 in the gut of straw-fed larvae.

The partial molar enthalpy and entropy of oxygen were determined as functions of the oxygen nonstoichiometry. The incorporation of Ni into LSFNb resulted in an increase in the partial molar entropy owing to the increased concentration of oxygen vacancies. A hollow fiber membrane based on LSFNbNi oxide with Ni-Fe decorated surfaces was investigated for use in a catalytic membrane reactor for the simultaneous oxygen separation and the partial oxidation of methane (POM) to syngas. An <em>in situ</em> exsolution of Ni-Fe nanoparticles on the inner membrane surface enhanced the oxygen exchange kinetics, increasing the oxygen flux by approximately 2.8-fold and reducing the effective activation energy by a factor of 1.5. The LSFNbNi hollow fiber membrane featuring exsolved Ni-Fe nanoparticles showed high catalytic activity in both synthetic air and POM-CO₂-splitting modes. Plane-wave density functional theory (DFT) was used to unravel the POM mechanism and model the exsolved Ni⁰ particles on the surface of the perovskite. DFT simulations showed that the oxidative elimination of H-atoms from methane (CH₄) on the FeO₂-terminated perovskite surface ceased upon the formation of stable methoxy species.

However, achieving selectivity in multifunctional molecules remains a significant challenge because of the nondiscriminative nature of conventional heterogeneous metal catalysts toward competing reducible groups. Specifically, the fundamental issue stems from the kinetic and thermodynamic overlap of reducible groups with similar redox potentials, making it difficult to suppress side reactions by optimizing the reaction conditions. This study proposes a “group recognition hydrogenation” strategy that achieves breakthrough selectivity by precisely controlling surface adsorption and activation processes. “Group recognition hydrogenation” is defined as a strategy that selectively distinguishes functional groups by regulating surface adsorption and activation in a spatially or electronically discriminative manner. It comprises functional group recognition adsorption and activation: the former enables preferential adsorption by modulating the adsorption strength, spatial constraints, and microenvironments, whereas the latter achieves selective activation by controlling the electronic structure and orbital interactions. This framework enables exclusive recognition of target functional groups while maintaining catalytic activity, providing a quantifiable approach for catalyst design. Future research directions in this field may include electronic–geometric structure decoupling and enantioselective control. This framework offers a novel perspective on selectivity control in heterogeneous catalysis with broad application prospects; therefore, researchers are encouraged to propose more effective selectivity control methods inspired by these concepts.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"4 2","pages":"Pages 142-148"},"PeriodicalIF":14.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148573320","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}

In this study, highly selective RuSn/SiO₂ catalysts were developed for the DMA-to-1,6-HDO transformation. The Sn addition demonstrated a promotion effect on the selectivity of 1,6-HDO due to the inhibition of the undesired hydrogenolysis of C–C and C–O bonds. The optimized 4Ru2Sn/SiO₂ catalyst afforded a high 1,6-HDO selectivity of ∼98.4% at ∼100% DMA conversion, almost double the value obtained over 4Ru/SiO₂ in H₂O under 120 °C and 8 MPa H₂. Additionally, the 4Ru2Sn/SiO₂ catalyst can be reusable up to five recycling cycles with almost unchanged activity and selectivity. Sn was found to be in close contact with the Ru centers in the form of SnO_<em>x</em>, which reduces the proportion of Ru⁰ species in RuSn/SiO₂, thereby significantly suppressing hydrogenolysis side reactions and enabling high selectivity toward 1,6-HDO in the aqueous phase.
