This article discusses a study on a new copper-based catalyst structure that significantly improves the efficiency of converting carbon dioxide into ethanol using electrochemical methods. Researchers stabilized copper oxides within carbon nanofibers, creating a Cu/CuₓO heterojunction. This structure showed exceptional performance in reducing CO₂ with high stability under varying electrical conditions, maintaining effectiveness even at high current densities. The findings, published by the Chinese Academy of Sciences, also highlight the benefits of using porous carbon nanofibers to enhance the exposure of active sites in the catalyst, leading to better performance and lower metal usage.

The article on Phys org discusses the potential of single-atom catalysts (SACs) in enhancing chemical reactions with greater efficiency and reduced waste. Researchers highlight the use of SACs in energy systems, emphasizing their ability to make reactions more efficient and less dependent on rare metals. The development of these catalysts relies on sophisticated synchrotron technology, which allows for detailed atomic-level analysis necessary to understand and improve SACs. The study underlines ongoing challenges in stability and scalability for commercial application. For more detailed information, you can read the full article on Phys org: https://lnkd.in/eEWpBM-H

🔋 Sodium-ion batteries are a promising alternative to lithium-ion ones, and for these devices, the choice of anode material is crucial. That's why CERIC PhD candidate Matej Gabrijelčič, supervisor Alen Vizintin and colleagues investigated the structural changes of hard carbon negative electrodes in Na-ion batteries induced by different carbonization temperatures and insertion of Na+ ions during sodiation. Check out their findings in our latest highlight: https://bit.ly/4fMiJdr

Are you curious about the future of fast-charging battery technologies? In our latest work co-First authored with Abbas under the Destiny PhD Programme MSCA COFUND we dive to explore the lithium storage behavior of AgNbO₃ perovskite, revealing its potential as a high-performance electrode material for next-generation batteries. We've uncovered a unique electrochemically driven activation process that significantly enhances the material's capacity and stability, and proceed to shed light on the processes involed in the activation mechanism. Dive into our findings published in Energy Storage Materials 2024! 🚀🔋 #BatteryTechnology #EnergyStorage #Innovation Friedrich Schiller University Jena Andrea Balducci

The Carbon-Binder-Domain (CBD) is an effective phase describing the aggregates of carbon additive and binder in #lithium ion #battery #electrodes. Its spatial distribution within the electrode volume and its effective porosity impact the electrochemical response of the electrode. Though the importance of the inner structure of the CBD network (specifically the CBD porosity) has been acknowledged, in state of the art works the CBD porosity is still assigned an arbitrary value, based more on educated guesses rather than experimental determination. Check out our latest paper "Carbon-Binder-Domain porosity extraction through lithium-ion battery electrode impedance data" just appeared in #Energy #Storage #Materials: https://lnkd.in/eQMhRrt6 Here, a novel methodology is reported for the determination of the CBD internal #porosity through the combination of #computational modelling and #experimental electrochemical impedance spectroscopy. Great collaboration between my group and Sergio Pinilla Yanguas who visited us a few months last year. Thank you Sergio for the great collaboration, and looking forward to our next paper together !
