Currently, electrocatalytic conversion of carbon dioxide into higher-value compounds is a promising approach. However, developing a stable and efficient catalyst with high selectivity for specific products remains a major challenge. Herein, we constructed a bismuth-based metal-organic framework (Bi-MOF) as a catalyst for the catalytic production of formic acid from carbon dioxide, to which different ratios of tin metal elements were doped. The catalyst Bi-MOF Sn6 exhibited excellent catalytic performance, with a formic acid selectivity of 80 % at −1.8 V and a current density of 25 mA/cm 2 . The catalytic mechanism of electrocatalytic CO 2 reduction reaction (ECO 2 RR) was revealed using density functional theory calculations. The work demonstrated that tin metal doping in Bi-MOF could effectively promote the catalytic process of ECO 2 RR, providing valuable insights for the subsequent design of more commercially available ECO 2 RR catalysts and more efficient CO 2 reduction systems.

Graphical Two systems including electrolysis-purification system (System I) and direct-electrolysis system (System II) were evaluated for their efficiency to produce fatty acid using cupriavidus sp. XH293. Our results shows that Sytem I was more favorable with higher yield of fatty acid, suggesting that decoupled electrochemical and microbial catalysis can be an efficient approach for CO 2 fixation driven by renewable energy. The heavy reliance on fossil fuels results in excessive greenhouse emissions, exacerbating environmental change, and global warming. CO 2 electrocatalysis has been widely studied and the products are limited to C 1-2 . Herein, we reported the integration of electrocatalysis and microbial catalysis for the synthesis of fatty acids from CO 2 . Here, we compared two decoupled MESs for fatty acid production, electrocatalysis-purification system (System I), and direct-electrocatalysis system (System II). Firstly, an upstream electrolysis was used to reduce CO 2 to formate using KHCO 3 and medium as electrolyte, respectively, with carbon nanofiber supported bismuth (Bi@PCF) catalyst. The results indicated that KHCO 3 as electrolyte had higher formate yield and Faraday efficiency than that of medium. Subsequently, a downstream microbial catalysis composed of Cupriavidus species was employed to synthesize fatty acids from formate in System I and System II, respectively. It was demonstrated that System I with the yield of 1.006 mg L −1 was more favorable for the synthesis of fatty acids than System II with the yield of 0.349 mg L −1 . These results suggested that decoupled electrochemical and microbial catalysis were an efficient approach for fixing CO 2 , indicating the great potential of a renewable energy driving artificial photosynthesis.

This study reports the mechanochemical synthesis of a highly efficient multicomponent CuInZnZrOx catalyst for the sorption-enhanced hydrogenation of CO2 to methanol. Through systematic optimization, the catalyst with a suitable indium loading of 0.5 wt % demonstrated favorable catalytic performance, achieving 22.5% CO2 conversion and 77.8% methanol selectivity under optimized reaction conditions (240 °C, 5 MPa, H2/CO2 = 10:1). Comprehensive structural characterization revealed that the incorporation of indium species significantly enhanced the dispersion of Cu nanoparticles while stabilizing the active Cu+/Cu0 sites, which are critical for both CO2 activation and methanol synthesis. The optimized CuIn0.5ZnZrOx catalyst exhibited remarkable long-term stability, maintaining over 95% of its initial activity during a 1000-h durability test, with a peak methanol space-time yield reaching 1974 g kgcat–1 h–1. Furthermore, when integrated with 13X zeolite in a sorption-enhanced reactor system, the catalyst system achieved a dramatic improvement in CO2 conversion (up to 65%), attributed to the in situ removal of the byproduct water that shifted the reaction equilibrium. This work not only elucidates the synergistic effects between indium modification and sorption-enhanced engineering but also presents a scalable and sustainable strategy for efficient CO2-to-methanol conversion, offering significant potential for industrial applications in carbon capture and utilization.

Electrochemical CO 2 reduction (ECR) to value-added products provides a pathway to reduce CO 2 emission and to enable a closed carbon cycle. Compared to powdered catalysts, self-supporting electrocatalysts have more prominent advantages such as high charge transfer capacity and the ability to serve directly as working electrodes without the need for binders. Herein, a self-supporting catalyst featuring SnO 2 nanoparticles incorporated into porous carbon nanofiber (SnO 2 -PCNF) was crafted via electrospinning followed by annealing in CO 2 . SnO 2 -PCNF can directly function as working electrode for ECR to produce HCOOH, achieving a high Faradaic efficiency of 92.3%. Also, the SnO 2 -PCNF can stably catalyze ECR process for more than 50 h. Theoretical calculations and in-situ Raman spectroscopy elucidate the underlying ECR mechanism over SnO 2 -PCNF, wherein the catalyst significantly reduces the energy barrier of the rate-determining step. This effectively suppresses the competitive hydrogen generation. This work provides some insights into design of binder-free and high-performance ECR electrocatalysts.

The rapid recombination of photoinduced charge carriers in semiconductors remains a significant challenge for their practical application in photocatalysis. This study presents the design of a step-scheme (S-scheme) heterojunction composed of carbon nitride (g-C3N4) and nickel-based metal–organic framework (Ni-MOF) to achieve enhanced charge separation. The establishment of an S-scheme charge transfer configuration at the interface of the Ni-MOF/g-C3N4heterostructure plays a pivotal role in enabling efficient charge carrier separation, and hence, high CO2photoreduction efficiency with a CO evolution rate of 1014.6 µmol g−1h−1and selectivity of 95% under simulated solar illumination. CO evolution represents an approximately 3.7-fold enhancement compared to pristine Ni-MOF. Density functional theory (DFT) calculations, supported by in situ irradiated X-ray photoelectron spectroscopy (XPS) and electron paramagnetic resonance (EPR) experimental results, confirmed the establishment of a well-defined and strongly bonded interface, which improves the charge transfer and separation following the S-scheme mechanism. This study sheds light on MOF-based S-scheme heterojunctions as fruitful and selective alternatives for practical CO2photoreduction.

The solubility of dyes in supercritical carbon dioxide (ScCO 2 ) is a critical parameter in their processing. This study focuses on triazine-based reactive disperse dyes. Their solubility in supercritical carbon dioxide was determined using the static weighing method. The measurement pressure range was 11-23 MPa, and the temperature range was 343.15-383.15 K. The experimental data were analyzed using multiple models. These models included density-based semi-empirical models (Chrastil, MST, Bartle, K-J, and SS) and state equation models (SRK and PR). Compared to the state equation method, the semi-empirical model method does not require the acquisition of complex physical parameters of the solute and exhibits superior correlation performance. The results indicate that the K-J model provides the best prediction accuracy for experimental data, with AARD% values of 3.18, 3.60, and 3.76, respectively. These findings provide critical solubility data and thermodynamic insights for the rational selection of carbon dioxide supercritical fluid dyes, dye structure design, and operational parameters for textile dyeing processes.

In this work, through mixing alkyl primary amines of C n H 2n+1 NH 2 （n=6, HA; n=12, DA; n=18, ODA） and disodium 4-formylbenzene-1, 3-disulfonate (DFD) at 1:1 mol ratio, three novel dynamic imine surfactants (DFD-HA, DFD-DA and DFD-ODA) were synthesized. The imine bond was verified by infrared spectroscopy (IR) and nuclear magnetic resonance (NMR). After preparing the emulsion, DFD-DA exhibited superior stability among the three surfactants at lower concentrations (< 20 mM). Subsequently, an emulsifier system (DFD-DA/LHSB) with excellent interfacial activity and emulsification stability was obtained by blending DFD-DA with lauramidopropyl hydroxy sulfobetaine (LHSB). The system effectively reduced the interfacial tension to the order of 10 −2 mN/m. At a total concentration of 5 g/L and mole ratio (DFD-DA: LHSB = 1:2), the emulsion could be stable for more than 60 days. Contact angle measurements substantiated the superior wettability inversion capability of the system, facilitating the formation of oil-in-water emulsions more effectively. Furthermore, this system possesses remarkable CO 2 responsiveness. After CO 2 injection, the emulsion can be completely demulsified within 45 s in a broad mole ratio range. Changing the relative content of DFD-DA and LHSB can also dynamically regulate the demulsification rate of emulsion. In contrast to previous imine surfactants, the system can achieve full demulsification under higher pH conditions (about 6.0), thereby significantly enhancing the response efficiency and alleviating the equipment corrosion. This discovery provides a new approach to tackling the problems associated with surfactant flooding and heavy oil demulsification, holding important implications for enhancing oil recovery (EOR).

The primary issues impeding oxygenation efficacy in extracorporeal membrane oxygenation (ECMO) are low CO 2 /O 2 selectivity and insufficient permeability of CO 2 . Herein, sulfonated polyphenylene oxide (SPPO) was chosen as a candidate for the oxygenation membrane material. The CO 2 -affinitive sulfonic acid groups on the molecular chain of SPPO enhance the interaction between CO 2 and the SPPO membrane; thereby, the CO 2 /O 2 selectivity is effectively enhanced. When the solid content of the casting solution is 23 %, the SPPO membrane achieves a CO 2 /O 2 selectivity of 17.0, almost as selective as human alveoli. The blood clotting time, red blood cell adhesion, platelet adhesion, and hemolysis ratio were employed to evaluate the blood compatibility of SPPO materials. The results demonstrated that the manufactured SPPO membranes exhibited good hemocompatibility. This work offers novel thinking for researching and applying effective artificial lung membranes.

Waterborne polyurethanes emulsions (WPU) based on polyethylene carbonate diol (PECD) were synthesized, characterized and modified by polypropylene carbonate diol (PPCD) and organosilicon KH-792. The mechanical, thermal and hydrolysis resistance properties of waterborne polyurethanes were comprehensively investigated. The results show that PECD based WPU has very excellent mechanical properties. The tensile strength and the elongation at break the PU was up to 73 MPa and 1040%, which was much higher than that reported for similar types of PPCD-based WPU. It was found that water absorption of PECD based WPU can be decreased dramatically, from 40.9% to 21.1%, after 50% PECD was replaced by PPCD, while tensile strength only decreased from 73.0 MPa to 63.4 MPa. The addition of KH-792 has great influence on PECD based WPU, when 1% KH-792 was added, the water absorption rate decreased from 21.1% to 11.88%, the mechanical strength remained at 63.3 MPa, the WPU film remained transparent after soaking in 80 ℃ hot water for 4 h.

CO 2 methanation is gaining renewed attention due to the emerging application needs such as the power-to-gas concept and long-term space exploration missions. Maximizing the amounts of interfacial sites generally regarded as the efficient active sites is considered to be one of the most direct means to enhance catalytic activity but few breakthroughs have been made. Here, Eu 3+ is introduced to Ni/CeO 2 to promote the Ni-CeO 2 interaction, resulting in a remarkable low-temperature CO 2 methanation activity. Structural characterization indicates that the Ni/CeEu(9:1) catalyst achieves higher Ni dispersion compared to Ni/CeO 2 , which consequently generates more interfacial sites. More interfacial sites enhance the proportions of bidentate carbonates closer to interfacial sites as a faster hydrogenated species during the catalytic process, leading to enhanced low-temperature CO 2 methanation activity over the Ni/CeEu(9:1) catalyst. This work provides a chemical strategy to enhance the amounts of active sites and bring insights into the origin of enhanced catalytic performance.

Efficient conversion of CO 2 to high value-added chemical products is a promising strategy for achieving carbon neutrality . Although the photocatalyst technique has been made widespread researched, highly efficient photoreduction CO 2 with metal-free photocatalysts remains a challenge. Herein, we report a zero-dimensional black phosphorus quantum dots (BPQDs)-decorated one-dimensional carbon nitride nanotubes (CNNT) photocatalyst that reduces CO 2 to CO with a rate of 44.6 μmol g –1 h –1 , which is better than the similar photocatalysts and pristine carbon nitride nanotubes . Synchrotron radiation XAFS measurements substantiate the construction of N-P electron transfer channels within BPQDs and CNNT. Time-resolved PL spectrum demonstrates the faster separated electron hole pairs . In situ irradiated X-ray photoelectron spectroscopy confirms the photogenerated-electron flow trend and the active site of photocatalytic reaction. Moreover, the main intermediate *COOH is verified by in situ FT-IR characterization which is corresponding to the previous research. The construction of atomic-level N-P charge transfer channel efficiently facilitates the charge transfer and accelerates the catalytic rate. This work provides a novel insight into the design of BPQDs-anchoring heterostructures for photocatalytic CO 2 reduction.

A highly effective catalyst is desired for CO 2 selective hydrogenation to methanol due to the kinetic limitation of this process, considering the heavy impact of CO 2 emission on global environment. Herein, a type of ammonization-treated CuMo catalyst was developed for CO 2 -to-methanol hydrogenation, which contains MoN and Mo 2 N species. The effect of catalyst preparation conditions on the physicochemical properties of the resulting sample was systematically investigated using multiple characterization techniques, including physical N 2 adsorption and desorption isotherms, XRD, HRTEM, XPS, Cu Auger spectra, H 2 -TPR and CO 2 -TPD. Structure-activity relationships analysis revealed that the proportion of Cu 0 and Mo δ+ (1 < δ < 4) in the catalyst is linearly correlated to the CO 2 transformative rate and methanol selectivity, respectively, which is considered to show synergistic effect on methanol production. Consequentially, the methanol production could reach up to 177.2 mg/g cat /h with a selectivity of 95.7 % at 230 °C and 4 MPa. In addition, the catalytic mechanism exploration employing in situ IR indicated the CO 2 hydrogenation towards methanol follows the formate route, and the Mo δ+ species facilitated the stabilization of CO 2 -derived reactive intermediates on the catalyst surface. Additionally, kinetic studies reveal methanol formation is primarily limited by CO 2 adsorption/activation rather than H 2 dissociation.
