However, developing catalysts that exhibit both high activity and selectivity remains a considerable challenge. Composite catalysts based on metal clusters supported on MXene have emerged as a promising candidate for CO₂ reduction. A thorough understanding of the catalytic mechanisms of CO₂ reduction utilizing MXene-based catalysts is crucial for advancing and optimizing these catalysts. In this study, the detailed reaction mechanism of CO₂ reduction on composite Ru_n@Mo₂TiC₂O₂ catalysts was investigated theoretically, employing the four-atom Ru₄ cluster as the model system. Electronic structure analysis revealed that the orbital interactions between the Ru₄ cluster and CO₂ play a pivotal role in determining the adsorption configuration of the CO₂ molecule. Specifically, CO₂ exhibits distinct adsorption modes on planar and tetrahedral Ru₄ clusters, leading to divergent CO₂ reduction pathways. Density functional theory (DFT) calculations suggest that the tetrahedral Ru₄ cluster demonstrates higher selectivity for the reduction of CO₂ to carbon monoxide (CO) compared to the planar configuration. However, the results indicate that although the planar Ru₄ cluster is predominant on the Mo₂TiC₂O₂ surface at room temperature, there is a coexistence of planar and tetrahedral Ru₄ clusters at the higher temperature used in photothermal catalysis. It suggests that the configuration of Ru₄@Mo₂TiC₂O₂ can be modulated by manipulating the reaction temperature, thereby adjusting the selectivity. This finding provides comprehensive insights into the CO₂ reduction mechanism facilitated by MXene-supported metal cluster catalysts. This work also highlights that the impact of temperature on the catalytic activity and selectivity of catalysts comprising metal clusters should be subjected to more rigorous investigation.</div></div>","PeriodicalId":350,"journal":{"name":"Journal of CO2 Utilization","volume":"95 ","pages":"Article 103088"},"PeriodicalIF":7.2,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143850208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Textile dyeing sludge (TDS) and corncob are two common types of carbonaceous solid wastes that are abundant and easily accessible. In this study, TDS and corncob were co-pyrolyzed to produce a series of CO₂ adsorption biochars (SCs). Results show that the synergetic and self-catalytic effects of the reaction between alkali/alkaline earth metals and the organic matters in TDS and corncob can increase biochar yield and enhance the ultra-micropore structure accounting for effective CO₂ adsorption. Moreover, the specific surface area of SC activated at 700 °C (SC700) was higher than corncob-based biochar. SC700 exhibited the highest CO₂ adsorption capacity (128.1 mg/g) among the SCs, which was more than double that of TDS biochar. This is primarily because SC700 had the highest specific surface area of ultra-micropores (544.38 m²/g) and ultra-micropore volume (0.16 cm³/g) among the SCs. After ten cycles tests, SC700 still showed good CO₂ adsorption-desorption performance, with a decrease of less than 1.5 %. The analysis of in situ DFIRT spectroscopy revealed that the CO₂ adsorption of SC700 involved both physical and chemical adsorption processes, with physical adsorption being dominant.

However, enhancement of CO₂ reduction capacity, ordering transformation of carbon, and rational application of carbon-deposited products remain challenging. This work explored the effect of Mg²⁺ doping (0.0–1.0 mol/mol) on the CO₂ reduction efficiency of MFO NPs, investigated the kinetics and mechanisms of CO₂ conversion to highly graphitized nanocarbon (HGC), and evaluated the potential of Mg_<em>X</em>MFO NPs@HGC as lithium-ion batterie anodes. Results showed that moderate Mg²⁺ doping neither destroyed the Fd-3m space group of MFO NPs but rather induced abundant Mn⁴⁺, Mn³⁺ (B-site) ions production with high H₂ reduction activity, which promoted the generation of substantial oxygen vacancies, thereby achieving efficient CO₂ capture and reduction. Mg_0.5MFO NPs exhibited superior CO₂ adsorption (129.13 ml/g) and reduction (151.87 ml/g) performance, and CO₂ followed an adsorption-stretching-polarization-reduction mechanism at the (111) plane. During the reduction of CO₂ by Mg_0.5MFO NPs, the controllable synthesis of HGC (5–50 nm, 82 % graphitization) was realized by increasing the temperature (300 °C→650–660 °C) and extending the time (1 min→30 min). Massive Mn²⁺ generated along with oxygen vacancies played a crucial catalytic role in the graphitization of carbon.

The system captures approximately 97 % of CO₂ and completely removes SO₂ from the RFCC flue gas. The integration of two inter-coolers significantly enhanced CO₂ capture efficiency by dissipating the heat generated during absorption, resulting in an 82 % reduction in CO₂ emissions compared to systems without inter-coolers. A comprehensive analysis of absorbent operating parameters—including MDEA flow rate (1100–1300 m³/h), temperature (40–50 °C), concentration (20–30 wt%), and absorption pressure (25–28 bar)—revealed that increasing all factors except temperature improved CO₂ capture performance.

The progressive incorporation of platinum on Cu/C nanoparticles significantly impacts the CO₂ electro-reduction performance in a 0.1 M KHCO₃ solution. The results revealed that Cu:Pt atomic ratios of 99:1 and 95:5 enhance formate production at mild potentials (-0.6 V vs. RHE) due to an improved water activation compared to monometallic Cu/C and, thus a higher availability of protons (or adsorbed hydrogen, *H) near the active sites.
