<p><strong>Czech researchers from Charles University, Prague, led by Pavla Eliášová, have developed an advanced photocathode that helps convert the greenhouse gas carbon dioxide into pure ethanol using sunlight. The new technology solves a long-standing problem of material degradation in water, achieves record conversion efficiency, and opens the way toward sustainable production of green fuels.</strong></p><p>Converting carbon dioxide (CO2) into useful fuels using solar energy represents the holy grail of modern green chemistry. The device enabling this conversion is called a <strong>solar reactor</strong>. Its key element is a <strong>photocathode</strong>: a material that absorbs light and enables the chemical reaction. Cuprous oxide long appeared to be an ideal material because it is inexpensive, readily available, and excels at capturing solar rays. In practice, however, it faced a fundamental obstacle: in an aqueous environment under light, it transforms and degrades extremely rapidly—much like iron undergoing swift corrosion—and loses its functionality within just tens of minutes.</p><p><strong>The team from the Chemistry Section of the Faculty of Science, CU</strong>, led by<strong> Pavla Eliášová</strong>, in collaboration with <strong>Tomáš Hrbek from the Faculty of Mathematics and Physics, CU</strong>, resolved this issue by creating a <strong>unique "nano-sandwich"</strong>. The scientists combined cuprous oxide with advanced two-dimensional materials called MXenes and, through precisely controlled heating, created an <strong>ultrathin layer of titanium dioxide</strong> on their surface. MXene modified in this way can rapidly drain electric charge from the cuprous oxide, thereby slowing down its decomposition. At the same time, it uses the charge further to convert carbon dioxide into liquid fuel.</p><p><i>"Surface-engineered MXene combined with cuprous oxide allowed us to unite the best of both materials. The copper base enables maximum utilization of light energy, while the conductive MXene framework ensures that the material remains active even after many hours of operation," </i>explains research<strong> team leader Pavla Eliášová from the Chemistry Section of the Faculty of Science, Charles University</strong>.</p><p>In laboratory tests, the new photocathode achieved a record solar-energy-to-ethanol conversion efficiency of <strong>2,74 %</strong>. A crucial improvement is the formation of only a single product. While other systems often produce a mixture of byproducts, the material designed by the research team produces pure ethanol as its sole liquid product, which significantly simplifies its potential industrial application.</p><p><i>"This is a major step forward for us. On our laboratory scale, the system works very well and produces ethanol over many hours. In the next step, we want to further reinforce the stability of the entire photocathode and begin testing on a larger scale and under real daylight conditions," </i>adds physical chemist Pavla Eliášová.</p><p><strong>The research was conducted within the international European project DESIRED (Horizon Europe), with support from the Charles University Research Centre (UNCE) and the L'Oréal-UNESCO For Women in Science program.</strong></p><blockquote><h4><strong>Article</strong></h4><h4><a target="_blank" rel="noopener noreferrer" href="https://advanced.onlinelibrary.wiley.com/doi/10.1002/aenm.71469"><span><strong>Surface-Engineered Ti3C2Tx MXene/Cu2O Photocathodes for Highly Selective Photoelectrocatalytic CO2 Reduction to Ethanol</strong></span></a></h4><p><span>Luis A.

While its low bandgap enables photoexcitation by visible light, long-term stability remains limited due to quick charge recombination and photocorrosion. Here, we enhanced charge separation and extraction by combining Cu<sub>2</sub>O with surface-engineered MXenes. In this novel architecture, TiO<sub>2</sub> grows in situ on the surface of Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub> and serves as a charge-transport layer, forming a junction with Cu<sub>2</sub>O. On the other side, the outer TiO<sub>2</sub> surface exposed to the CO<sub>2</sub>-saturated electrolyte offers catalytically active sites for CO<sub>2</sub> reduction. Acting as a central layer, the MXene conductive backbone provides an electronically continuous pathway for electron transport. In PEC CO<sub>2</sub>RR, the photocathode containing 50 wt.% of MXene and a balanced amount of TiO<sub>2</sub> on the Ti<sub>3</sub>C<sub>2</sub> surface outperformed the best Cu/Cu<sub>x</sub>O-based systems operating in non-organic electrolytes reported in the literature. The FTO/Cu<sub>2</sub>O/ml-Ti<sub>3</sub>C<sub>2</sub>T<sub>x</sub>-350-N<sub>2</sub> photocathode reached 8.4&nbsp;µmol&nbsp;cm<sup>−2</sup> h<sup>−1</sup> ethanol production rate and 2.74% solar-to-ethanol efficiency after 2&nbsp;h. Moreover, pairing TiO<sub>2</sub>-MXene with Cu<sub>2</sub>O significantly stabilized the photocathode, which maintained 76% of the ethanol production rate after 6 h. Overall, our results establish surface-engineered Cu<sub>2</sub>O/TiO<sub>2</sub>-MXene heterostructures as a solid platform for highly selective, visible-light-driven ethanol production with significantly improved operational stability.</p>

<div><div><p><strong>Protons play a central role in many chemical reactions in living organisms.

In contrast to techniques that record time-averaged proton positions, like nuclear magnetic resonance, photoelectron spectroscopy captures instantaneous proton distribution due to its ultrafast probing time scale. The method is, therefore, uniquely sensitive to the occurrence of proton sharing in an aqueous environment, as demonstrated here. We only observe significant proton sharing dynamics in maleic acid, where its monoanionic form shows a single, delocalized peak in the carbon 1s spectrum. Conversely, succinic acid, fumaric acid, malic acid, glutaric acid, and citric acid exhibit distinct peaks corresponding to separate, localized COOH and COO<sup>–</sup> groups, instead of shared protons. Our results reveal that intramolecular proton sharing in water is rather an exception for most biologically relevant polycarboxylic acids. This highlights the importance of enzyme-driven structural changes of polycarboxylic acids associated with proton sharing during metabolic processes.</p></div>

Following the successful market introduction, LECO will present an overview of the latest technological innovations and performance enhancements of this GDS platform.</strong></p><p>The webinar will briefly revisit the basic working principles of Glow Discharge Spectroscopy, explaining how controlled sputtering combined with optical emission detection enables precise elemental analysis. Emphasis will be placed on the strengths of GDS in bulk analysis as well as composition depth profiling (CDP), demonstrating how both surface-near and bulk material information can be obtained with high accuracy and reproducibility.</p><p>A series of application examples will be shown to highlight the analytical advantages of the GDS 900/950 series. Grey cast iron, for example, can be analyzed directly without melting or the formation of chilled cast iron, making the results independent of the metallurgical history of the sample. The method is free of memory effects, allowing rapid matrix changes from sample to sample with minimal changeover effort.</p><p>Further benefits discussed include the very low argon consumption, the low consumption of CRM and SUS materials. No special sample preparation is required, as existing preparation methods are fully compatible with the GDS 900 series.</p><p>Finally, the webinar will address calibration concepts, highlighting the use of linear calibration curves that provide wide analytical ranges with limited interferences. Stable calibrations with reduced drift behavior minimize the need for frequent recalibration, beyond routine quality control checks, ensuring long-term reliability and efficiency in routine laboratory operation.</p><blockquote><p><strong>Presenter: </strong>Michael Jakob (Elemental Field Product Manager)</p></blockquote></div></div></div>
