“…were prepared at a concentration of 0.003 M and used throughout the experiment. The pH effect of the different test analytes with different dye solutions was analyzed in acidic (2,4,6), neutral, and basic (9,12) solutions. Each dye solution (10 mL) was treated with 1 mL of 0.5 ppm test solution (ethanol/formic acid/methanol) separately in the adjusted pH.…”

Carbon dioxide (CO2) is a greenhouse gas in the atmosphere and scientists are working on converting it to useful products, thereby reducing its quantity in the atmosphere. For converting CO2, different approaches are used, and among them, electrochemistry is found to be the most common and more efficient technique. Current methods for detecting the products of electrochemical CO2 conversion are time-consuming and complex. To combat this, a simple, cost-effective colorimetric method has been developed to detect methanol, ethanol, and formic acid, which are formed electrochemically from CO2. In the present work, the highly efficient sensitive dyes were successfully established to detect these three compounds under optimized conditions. These dyes demonstrated excellent selectivity and showed no cross-reaction with other products generated in the CO2 conversion system. In the analysis using these three compounds, this strategy shows good specificity and limit of detection (LOD, ~0.03–0.06 ppm). A cost-effective and sensitive Internet of Things (IoT) colorimetric sensor prototype was developed to implement these dyes systems for practical and real-time application. Employing the dyes as sensing elements, the prototype exhibits unique red, green, and blue (RGB) values upon exposure to test solutions with a short response time of 2 s. Detection of these compounds via this new approach has been proven effective by comparing them with nuclear magnetic resonance (NMR). This novel approach can replace heavy-duty instruments such as high-pressure liquid chromatography (HPLC), gas chromatography (G.C.), and NMR due to its extraordinary selectivity and rapidity.

“…At the same time, an Allam cycle operating in tandem with CCU, and water electrolysis could utilize partly or entirely the oxygen produced from the latter activity. An Allam cycle was successfully demonstrated in 2016 at a 50 MW th test facility at La Porte, Texas, while a utility-scale project (≈300 MWe) is expected to be operational by 2026. , In a recent study, Fernández-Torres et al investigated the integration of oxy-combustion with CCU for high-quality gasoline production from atmospheric CO 2 and H 2 , and compared it to the conventional alternative with a gas turbine along with additional heat recovery by the steam generator. They found that oxy-combustion cycles outperform conventional utilization in terms of mass and carbon efficiency.…”

The consequences of global warming call for a shift to circular manufacturing practices. In this context, carbon capture and utilization (CCU) has become a promising alternative toward a low-emitting chemical sector. This study addresses for the first time the design of an integrated CO 2 refinery and compares it against the business-as-usual (BAU) counterpart. The refinery, which utilizes atmospheric CO 2 , comprises three synthesis steps and coproduces liquefied petroleum gas, olefins, aromatics, and methanol using technologies that were so far studied decoupled from each other, hence omitting their potential synergies. Our integrated assessment also considers two residual gas utilization (RGU) designs to enhance the refinery's efficiency. Our analysis shows that a centralized cluster with an Allam cycle for RGU can drastically reduce the global warming impact relative to the BAU (by ≈135%) while simultaneously improving impacts on human health, ecosystems, and resources, thereby avoiding burden-shifting toward human health previously observed in some CCU routes. These benefits emerge from (i) recycling CO 2 from the cycle, amounting to 11.2% of the total feedstock, thus requiring less capture capacity, and (ii) reducing the electricity use while increasing heating as a trade-off. The performance of the integrated refinery depends on the national grid, while its high cost relative to the BAU is due to the use of expensive electrolytic H 2 and atmospheric CO 2 feedstock. Overall, our work highlights the importance of integrating CCU technologies within chemical clusters to improve their economic and environmental performance further.

Bismuth-based catalysts exhibit excellent activity and selectivity for the electroreduction of carbon dioxide (CO 2 ). However, single-component bismuth-based catalysts are not satisfactory for the electrochemical reduction of CO 2 to formic acid, mainly due to their high hydrogen production, low electrical conductivity, and small catalytic current density. Herein, we used a coordination strategy to recombine Bi and In at the molecular level to form Bi/In bimetallic metal−organic frameworks (MOFs), which were then calcined to obtain MOF-derived Bi/In bimetallic oxide nanoparticles embedded in carbon networks. Thanks to the synergistic effect of bimetallic components, high specific surface area, suitable pore size distribution, and high electrical conductivity of the carbon network, the material exhibits excellent activity and selectivity for electroreduction of CO 2 to formate. In H-type electrolyzers, the formate Faradaic efficiency reaches 91% at −0.9 V (vs RHE) and does not decrease significantly within 48 h. In situ Fourier transform infrared spectroscopy confirms the reaction intermediates and reveals that CO 2 electroreduction is dominant by the *OCHO pathway.
