New paper published in the Journal of Industrial and Engineering Chemistry. In cooperation with former group member Choonsoo Kim (now at Kongju University, Korea), we have used redox flow desalination for the valorization of tetramethylammonium hydroxide as a value-added organic compounds from wastewater which is widely being used as an etching solvent, photoresist developer, and […]
New perspective paper published in Communications Materials. The high entropy concept is ideally suited for MXenes but also capable to be a unique tool to tailor and improve electrochemical properties in other materials. Multiple principal element or high-entropy materials have recently been studied in the two-dimensional (2D) materials phase space. These promising classes of materials […]

Very happy to see both Behnoosh Bornamehr and Mohammad Torkamanzadeh winning in the essay competition on open science / open data of Saarland University! This makes for a 100% win rate for applicants from our team 😉 Open access is not without challenges and caveats and the journey toward a world of true open science […]
New paper published in the Journal of the American Ceramic Society on the synthesis of new hybrid electrode materials for Li-ion batteries (LIBs). Through controlled oxidation of layered Ti2SnC, we were able to obtain TiO2-SnO2-C/carbide hybrid materials using two different methods: partial oxidation in an open-air furnace (OAF) and rapid thermal annealing (RTA). The resulting […]
New paper published in ACS Applied Nano Materials. Rolling bearings need lubrication to operate smoothly, but when traditional methods fail, multiwall carbon nanotubes (MWCNT) can come to the rescue. To understand how MWCNTs lubricate highly loaded contacts, we combined experimentation and large-scale molecular dynamics simulations. We applied tribometry to iron plates coated with different types […]
New paper published in Journal of Energy Storage on MXene battery electrode recycling. Even the most wonderful electrode material, some sooner than later, will degrade. Even the most wonderful battery, regardless of the used chemistry, will see the end of its life. Battery recycling, using hydrometallurgical or pyrometallurgical pathways, is very energy consuming. So are […]
New paper published in ChemSusChem in collaboration with the Kickelbick-Group at Saarland University. We have developed an exciting new class of inorganic-organic hybrid materials with redox-active components that have great potential for use in lithium-ion batteries (LIBs). The materials were prepared using an aqueous precipitation reaction of ammonium heptamolybdate (AHM) with para-phenylenediamine (PPD), and a […]

It is a privilege to receive, after 2018 and 2021, the recognition as 2022 Highly Cited Researcher (HRC) by Clarivate. Only 6,938 out of abut 8M researchers have received this recognition. Citation numbers are not the most important parameter in science, but I am grateful to our team and collaborators that the community so well […]
New paper published in Carbon. This is our latest work from our collaboration with our Austrian partners now being published in the January issue of Carbon. Combining the expertise in catalysis of the Eder group (TU Vienna) with the innovative carbon spherogel material developed by Michael Elsaesser from the Hüsing Group (Paris Lodron Universität Salzburg) […]
After a lot of work by our Ph.D. students Stefanie Arnold and Lei Wang, our invited article in the Wiley journal SMALL on the dual-use of seawater batteries for energy storage and water desalination. Seawater batteries are a unique type of device that capitalizes, in the most common design, on a ceramic separator, an electrocatalytic reaction on one electrode […]
New paper published in ACS Omega. Batteries employing transition-metal sulfides enable high-charge storage capacities, but polysulfide shuttling and volume expansion cause structural disintegration and early capacity fading. The design of heterostructures combining metal sulfides and carbon with an optimized morphology can effectively address these issues. Our work introduces dopamine-coated copper Prussian blue (CuPB) analogue as […]
I am honored to receive the 2022 Zhaowu Tian Prize for Energy Electrochemistry. This award by the International Society of Electrochemistry recognizes the achievements in the field of electrochemistry for energy of my team and I. I am fortunate to join the list of awardees which includes from past years Xiangfeng Duan (2017), Fabio la Mantia (2018), Zhichuan […]
New paper published in Electrochimica Acta on Ni-decorated AgAu alloy graphene/cobalt hydroxide electrodes for micro-supercapacitors to obtain high-performance micro-supercapacitors. A nanocomposite of graphene, cobalt hydroxide and nickel can was obtained from using gold-silver alloy lines. Using a two-step electrodeposition method, the scaly morphology is pre-deposited on a Ni film, followed by the interconnecting corrugated graphene/cobalt […]
Welcome to our new Postdoc Dr. Kaitlyn Prenger! Kaitlyn is a graduate of Tulane University from the esteemed team of Michael Naguib and will work on novel 2D (and other) materials for sustainable electrochemical applications.
Stefanie Arnold gives an oral presentation with the title “Design Matters: The Path to High-Performance Antimony / MXene Hybrid Electrodes for Sodium-Ion Batteries” at the MSE2022 conference in Darmstadt. This was joint work with Riccardo Ruffo‘s team and Stefano Marchionna (Italy).
new paper published in ACS Energy Letters on continuous electrochemical lithium-ion extraction. We used a redox electrolyte “engine” to drive the ion transfer (in our case: potassium ferricyanide). Employing a pair of ceramic lithium superionic conductor (LISICON) membranes meant that only Lithium ions were accessible to the redox electrolyte for charge compensation. And to complement […]
