Fe-CeO₂ is the only one showing thermal CO₂ deoxygenation to CO at below 700 °C after reduction. XRD analyses of as prepared Fe-CeO₂ demonstrate the presence of segregated Fe₂O₃ and CeO₂ phases with partial mixing. Both Fe₂O₃ phase and CeO₂ phase show redox during sequential TPR (temperature-programmed reduction)-CO₂-TPRx (temperature-programmed reaction) up to 700 °C. The evolved Fe⁰ after TPR appears to be the main active phase for CO₂ deoxygenation which becomes oxidized back to Fe₂O₃ after CO₂-TPRx. The results indicate that the interface (interphase) between Fe-domain and CeO₂-domain is involved leading to the observed deoxygenation reactivity. That the stripped oxygen from CO₂ over Fe-domain can spillover to CeO₂ domain is considered as a possible explanation. We perform isothermal CO₂ deoxygenation test at 600 °C over TPR-treated Fe-CeO₂ using oxygen-conducting membrane reactor, and the CO₂ deoxygenation capacity is found significantly higher than that observed when in the absence of oxygen conducting membrane.

In a recent contribution, carbon-supported Bi-Sn-Sb nanoparticles with different atomic ratios were prepared and evaluated for the electrocatalytic reduction of CO₂ to formate, assessing their performance in terms of activity, selectivity, and stability under working conditions in an H-type cell. Under this electrochemical reactor configuration, the results clearly indicated that the incorporation of small amounts of Sb and Sn into Bi significantly enhanced stability without substantially affecting activity and selectivity, achieving promising results with Bi₈₀Sn₁₀Sb₁₀ electrocatalysts. Here, we report the use of Bi-Sn-Sb-based Gas Diffusion Electrodes (GDEs) in a flow electrochemical reactor for the electrocatalytic reduction of CO₂ to formate. The study also aims to rigorously compare the performance of Bi-Sn-Sb GDEs with that of analogous GDEs based solely on Bi or Sn. When compared to relevant references, the Bi-Sn-Sb catalyst demonstrates performance metrics that reflect comparable system efficiency to the Bi and Sn cathodes previously used by our research group, operating at current densities up to 200 mA·cm⁻² and achieving formate concentrations of approximately 15 g·L⁻¹. Furthermore, these materials exhibited technical feasibility, remaining stable throughout the 5-hour experiment with less than a 10 % decrease in concentration.

Based on systematic characterization and evaluation, it was found that Zn is the primary active component in the catalytic system for activating C₂H₆, but it is merely active towards CO₂, leading to rapid catalyst deactivation. Under the influence of Ga species, CO₂ can readily engage into the reaction network. During the initial stage of the reaction, the activated CO₂ primarily participants in dry reforming with C₂H_6-x species that rapidly formed on highly active Zn sites. However, the rapid cleavage of C-H bonds on these Zn sites leads to significant carbon deposition and subsequent deactivation. Following this rapid deactivation phase, CO₂ becomes involved in the reaction through the reverse water-gas shift (RWGS) reaction and carbon elimination reactions, thereby shifting the reaction equilibrium towards C₂H₄ formation while alleviating the accumulation of carbon deposition and thus enhancing stability. With the optimum catalyst (Ga_0.27ZnZ5), excellent and stable performance with 22.64 % C₂H₄ yield and nearly 100 % selectivity could be achieved after an induction period of ca. 100 minutes, these are among the highest values reported so far.</div></div>","PeriodicalId":350,"journal":{"name":"Journal of CO2 Utilization","volume":"95 ","pages":"Article 103066"},"PeriodicalIF":7.2,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143680412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, activated carbon (AC)-supported Ni catalysts modified with different promoters (Mg, Ca, La, Ce) were investigated for MW-DRM process. As proved by the experiment results, Ca-promoted catalyst exhibited the worst reforming activity and stability in the MW-DRM and conventional heating DRM (CH-DRM) processes due to the severe carbon gasification of AC support and the severe sintering of the active metal. Compared to Mg, Ca, and La promoters, Ni-Ce/AC catalyst was demonstrated the optimum catalyst for MW-DRM process, which showed the most excellent stability with good reforming activity over 96 % and 98 % for CH₄ and CO₂ conversion rates, respectively. By converting MW energy attenuation into heat and plasma, the locally-formed high-energy active sites composed of adjacent Ni, CeO₂ and AC support of the Ni-Ce/AC catalyst could contribute to achieving the effective and localized activation of CH₄ and CO₂ molecules, thus leading to the enhancement of the reforming activity and the reduction of the loss of AC support due to CO₂ gasification. Moreover, MW heating method could avoid the excessive consumption of the AC support in Ni-Ce/AC by increasing the graphitization degree of AC, thus prolonging the lifetime of the AC-based catalysts.

Emerging CO₂-augmented leaching techniques, including CO₂-water, supercritical CO₂, CO₂-ammonia, ionic-liquid, and CO₂-cyanide leaching have shown improved performance for a limited number of minerals at the laboratory scale. Similar to its role in leaching, CO₂ can act as a depressant or pH modifier in flotation, improving process selectivity and efficiency while reducing the need for additional chemicals. For water treatment, CO₂ facilitates the precipitation of heavy metals and contaminants under optimal conditions. CO₂ sequestration through mineral carbonation provides a sustainable method for locking CO₂ in stable mineral forms, utilizing tailings for both waste management and carbon capture. CO₂ utilization in flotation, leaching, and water treatment is currently limited to lab-scale experiments, emphasizing the need for scale-up trials to fully assess technical feasibility and identify potential bottlenecks associated with large-scale implementation.
