The utilization of urea as a nitrogen source during the hydrothermal process significantly influenced the morphology and defects of the obtained catalyst. Within an optimal range, the actual nitrogen promoter content could be controlled by altering the amount of urea introduced. The presence of a nitrogen promoter not only impacts catalytic activity but also plays a crucial role in product distribution. The FeC-N catalyst exhibited 32.0% selectivity toward light olefins, with a CO₂ conversion of 26.8%. The improvement in catalytic performance correlated with the specific surface area, dispersion of iron species, number of defect sites, and content of pyrrolic N species. Moreover, the enhanced selectivity for light olefins can be attributed to easier desorption from the FeC-N catalyst, thereby avoiding the over-hydrogenation of light olefins to paraffins.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"3 1","pages":"Pages 36-43"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724853","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}

Herein, anchoring the H₂ production sites onto the surface of CdIn₂S₄ (CIS) with a nanoscale hollow sphere allows for the photoconversion of CO₂ into syngas and water splitting to H₂. The CO/H₂ ratio can be realized in a remarkably wide range from 1:0.38 to 1:3.76. The optimized CIS/Co-PBA/NaY-5 hybrid exhibits superior photocatalytic syngas evolution up to 1458.48 μmol·g⁻¹·h⁻¹ (H₂/CO, 1152.29/306.19 μmol·g⁻¹·h⁻¹), and the H₂ evolution rate increases by 431.70% compared with CIS. The CIS/Co-PBA/NaY-5 hybrid exhibited not only superior H₂ evolution but also recyclability. The experimental, energy-dispersive X-ray spectroscopy, and electron spin resonance results indicate that the Co sites serve as H₂ production sites and promote the H₂ evolution reaction.

Based on the solubility of the two alcohols, the methanol and pentanol pretreatments are homogeneous and biphasic, respectively. Carbon flow analysis revealed that 1 kg of corn stalk (CS) yielded 111.9 g of lignin with the homogeneous pretreatment (lignin yield: 60.0%), while 149.8 g of lignin was obtained with the biphasic pretreatment (lignin yield: 80.3%).

Fourier Transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD) were employed to verify the component fractionation results. The Hansen solubility parameter and combined severity factor analysis were used to evaluate the effects of various factors on component fractionation.

In microalgae, ALE has been employed to improve resilience against varying environmental and stress factors and increase carbon capture efficiency, and for the production of valuable bioproducts through gradual accumulation of beneficial mutations following manual or automated selection. Furthermore, advancements in the understanding of microbial symbiotic relationships in the phycosphere have facilitated microbiome optimization in microalgal cultivation systems, significantly improving their functionality and productivity. In this study, we provide a comprehensive overview of the latest advancements in ALE and microbiome optimization of microalgae for CCUS across different carbon emission scenarios, including flue gas, biogas, wastewater, and landfill leachate. We further discuss the current challenges and future directions for the integration of ALE with microbiome optimization, focusing on the potential synergies of these methodologies.

However, it is challenging to achieve a metal–nitrogen–carbon (M–N–C) catalyst that exhibits high resistance to corrosive Cl^– in seawater-based electrolytes and possesses a strengthened binding affinity with O₂, which enables catalysts with an optimized oxygen reduction reaction (ORR) and enhances the applicability of S-ZABs. Herein, we propose a combined wet chemistry-pyrolysis strategy to obtain atomically dispersed Fe-decorated nitrogen-doped mesoporous carbon spheres (N-MCS-Fe-900). Benefiting from the capacity of the Fe decorations to form the edge-hosted aerophilic FeN₄-O₂ sites at the optimized three-phase interface, N-MCS-Fe-900 affords the enhanced resistance of the active Fe sites to corrosive Cl^–, as well as improved interaction with O₂, thereby facilitating the ORR process. As expected, the N-MCS-Fe-900 delivers high half wave potential of 0.90 V and kinetic current density of 18.61 mA cm⁻² at 0.85 V in seawater-based 0.1 M KOH. More importantly, the S-ZABs equipped with N-MCS-Fe-900 exhibited long-term stability under a high current density for over 140 h without voltage decay. Theoretical calculations and electrochemical performance evaluations collectively revealed the superior catalytic efficacy and genesis of this activity in N-MCS-Fe-900, which features edge-hosted FeN₄-O₂ sites at the stable three-phase interface in seawater electrolytes.

If CO₂ is injected into NGH sediments, CH₄ is released and CO₂ hydrate formed. The extraction of gas from NGH, combined with carbon capture, presents significant potential advantages in the energy infrastructure and various economic and political contexts, aligning with future green policies. This study contributes to the advancement of knowledge by reviewing the findings of a three-year Italian research project focused on methane recovery and carbon dioxide disposal in NGH. The consortium comprises seven multidisciplinary Italian partners. This study introduces a novel process wherein the CO₂–CH₄ replacement process is integrated with methane purification and CO₂ recirculation, which has been experimentally tested and represents a new advancement in gas hydrate science. Experimental tests at the microscopic and macroscopic levels showed that the efficiency of the process strongly depends on the mutual influence of the properties of water, sediment, and the involved gaseous species. Energy evaluations show that the ratio between the energy spent to complete an entire cycle of replacement and recirculation over the stored energy in the recovered methane is 17%, resulting in a beneficial energy balance, while economic analysis shows that the transition could generate—even in the short term—large high-impact cash-out.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"2 4","pages":"Pages 351-365"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098284","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}
