CO2 TO CO SK Innovation Institute of Environmental Science & Technology, an R&D organization of SK Innovation Co. Ltd. has successfully manufactured about 1 kg/d of CO using diatomic catalyst (DAC) technology, which selectively converts CO2 into CO in an electrochemical process. The results of this demonstration were published, the diatomic catalyst consists of heteronuclear Ni and Fe sites anchored on N-doped carbon material (NiFe-DAC). A “unique coordination structure of hetero-diatomic site” enables the catalyst to preferentially convert CO2 into CO with a CO selectivity of more than 97% under an industrially-relevant current density of 200 mA/cm2 in 25-cm2 and 140-cm2 zerogap membrane electrode assembly (MEA) CO2 electrolyzers. A scale-up demonstration using a 140 cm2 four-cell stack achieves an exclusive CO2-to-CO generation rate of about 45 L/h.

Exploring Iridium as a Catalyst in Electrolyzers 🌟 As we advance toward sustainable energy solutions, finding efficient and cost-effective materials for electrolyzers is critical. Iridium stands out due to its exceptional stability and high catalytic activity, especially in the oxygen evolution reaction (OER) within electrolyzers like Proton Exchange Membrane (PEM) systems. Its performance in harsh environments and its ability to drive OER effectively make it a valuable asset in improving water splitting technologies and overall energy conversion rates. However, despite its advantages, iridium's high cost and limited availability present challenges for widespread adoption. Researchers are actively working to address these issues by exploring ways to reduce costs and enhance performance, often through innovative alloys or combinations with other metals. Iridium remains a pivotal element in advancing green energy solutions, driving both efficiency and innovation in the field. https://lnkd.in/dv47kntH #Electrolyzers #Iridium #SustainableEnergy #Catalysts #GreenTechnology #Innovation #EnergyStorage #HydrogenEconomy

#Electrocatalytic Enhancement of CO Methanation at the Metal–#Electrolyte Interface Studied Using In Situ X-ray #Photoelectron #Spectroscopy by Christoph W. Thurner et al. C 2023, 9(4), 106; https://lnkd.in/dztXt93p Current number of article views: 1259 Abstract For the direct reduction of CO2 and H2O in solid oxide electrolysis cells (SOECs) with cermet electrodes toward methane, a fundamental understanding of the role of elemental carbon as a key intermediate within the reaction pathway is of eminent interest. The present synchrotron-based in situ near-ambient-pressure X-ray photoelectron spectroscopy (NAP-XPS) study shows that alloying of Ni/yttria-stabilized-zirconia (YSZ) cermet electrodes with Cu can be used to control the electrochemical accumulation of interfacial carbon and to optimize its reactivity toward CO2. In the presence of syngas, sufficiently high cathodic potentials induce excess methane on the studied Ni/yttria-stabilized-zirconia (YSZ)-, NiCu/YSZ- and Pt/gadolinium-doped-ceria (GDC) cermet systems. The hydrogenation of carbon, resulting from CO activation at the triple-phase boundary of Pt/GDC, is most efficient. Keywords: SOEC; methanation; #electrocatalysis; NAP-#XPS

Delighted to share that our recent paper, titled "Efficient #hydrogen splitting via single atom catalysts supported on Zn12O12 nanocage for sustainable clean fuel production" has been published at the International Journal of Hydrogen Energy (Q1 Journal). Hydrogen, as a #renewable_energy source, offers numerous advantages such as high energy density, zero carbon dioxide emissions, lightweight properties, and non-toxicity, making it a promising candidate for future #energy_systems. In many industrial processes, #hydrogen_dissociation reactions play a crucial role. These reactions involve breaking down H2 molecules into reactive hydrogen atoms, which then bind with support materials or catalysts. This enables the storage of significant amounts of hydrogen at low temperatures and pressures. The primary objective of our study is to design first-row transition metals (Sc–Zn) doped zinc oxide (Zn12O12) and investigate their thermodynamic stability, electronic properties, and ability to facilitate hydrogen dissociation reactions through DFT simulations. For more details, the paper is attached.
