New paper published in Nature Communication. This highly collaborative work (spearheaded by Dr. Gündoğ Yücesan) presents polyphosphonate covalent organic frameworks (COFs) constructed via P-O-P linkages, synthesized through a one-step condensation reaction. This process involves heating a hydrogen-bonded precursor made from phenylphosphonic acid and porphyrin, without chemical reagents. At temperatures above 210 °C, the COF transforms into […]

New research paper from our collaboration with Michael Naguib: “Nitrogen-Doped Graphene-Like Carbon Intercalated MXene Heterostructure Electrodes for Enhanced Sodium- and Lithium-Ion Storage” published in Advanced Science. We’ve developed a novel N-doped graphene-like carbon intercalated Ti3C2Tx (NGC-Ti3C2Tx) heterostructure. But wait… why would one want to add something in-between the MX-layers, the wonderful interlayer space that should […]
New paper on solvation effects inside carbon nanopores during electrosorption published in Carbon. Our British-German study explores the solvation effects on ion adsorption and electrosorption within carbon micropores, employing nuclear magnetic resonance (NMR) spectroscopy to gain insights. Our data investigate how ionophilicity and ionophobicity – the tendency of ions to be uptaken by uncharged nanopores […]
New paper published in Chemical Engineering Journal on “A sustainable approach: Repurposing harmful algal biomass as carbon-based catalysts for nitrogen fertilizer electrosynthesis from nitrate and CO2“. 📜 Our research focuses on repurposing harmful algal blooms (HABs) biomass into carbon-based catalysts, specifically Cu1Mo1/NC, for the electrosynthesis of nitrogen fertilizers (urea and ammonia) from nitrate and CO2. […]
New paper published on “Freestanding Films of Reduced Graphene Oxide Fully Decorated with Prussian Blue Nanoparticles for Hydrogen Peroxide Sensing” in ACS Omega. This work explores freestanding graphene/Prussian blue (PB) electrodes for detecting hydrogen peroxide (H2O2). Using a two-step method, we synthesized reduced graphene oxide/PAni/Fe2O3 freestanding films, followed by electrochemical deposition of PB nanoparticles. This […]

New review article “Functional gel-based electrochemical energy storage” published Chemistry of Materials. This paper reviews the research field of gel polymer electrolytes (GPEs), which combine the ionic conductivity of liquid electrolytes with the mechanical stability of solid materials. GPEs are versatile materials in various electrochemical applications, including sensors, actuators, and energy storage devices. These quasi-solid […]
Panyu Ren gives a poster presentation on the topic “Carbon additives: friend or foe of capacitive deionization with activated carbon?” at the 37th Topical Meeting of the International Society of Electrochemistry (ISE) in Stresa, Italy.
Thanks to the creativity of Uwe Bellhäuser and the patience and positive energy of our whole team, we are happy to launch now our new team feature video – to share our team’s excitement about research and to showcase the real heroes and heroines of science: the people of our group! Enjoy the video and […]
Jonas Oehm presents a poster with the title “On the development of a digital data management platform for battery material and processing data?” at the 245th Meeting of the Electrochemical Society in San Francisco (USA).
It is a tradition at the Natural Science Faculty of Universität des Saarlandes to have the annual PhD Day in the Aula. This year, 60 PhD student presented their research, ranging from artificial muscles, to much real mucus, from 3D printed nanofluids to very solid metals, from quantum communication to quorum sensing inhibitors. From our […]
