Polycondensation as a Universal Method for Preparing High-density Single-atom Catalyst Libraries

Paul Joseph Dyson, Mounir Driss Mensi, Pascal Miéville, Laura Piveteau, Xunhui Wang, Xinbang Wu, Daniel Ortiz Trujillo, Miyeon Chang, Ariana Serban, Timo Markus Oskar Felder

Single-atom catalysts (SACs) present a promising subclass of classic heterogeneous catalysts by maximizing metal dispersion and enhancing efficiency. Although high-density SACs (HD-SACs) are reported, their synthesis is typically constrained to specific me ...

Non-fluorinated Asymmetric Ether Electrolytes with Controlled Solvation Structure for High-voltage Lithium Metal Batteries

Mounir Driss Mensi

Ether-based electrolytes are well-suited for lithium metal anodes but suffer from limited oxidative stability, restricting their use with high-voltage cathodes. Fluorination has been employed to mitigate this challenge; however, their recycling poses envir ...

Strain-induced rubidium incorporation into wide-bandgap perovskites reduces photovoltage loss

Michael Graetzel, Shaik Mohammed Zakeeruddin, David Lyndon Emsley, Ursula Röthlisberger, Mounir Driss Mensi, Felix Thomas Eickemeyer, Pascal Alexander Schouwink, Lukas Pfeifer, Jing Gao, Virginia Carnevali

A-site cation mixing can enhance the photovoltaic performance of a wide-bandgap (WBG) perovskite, but rubidium (Rb) cation mixing generally forms a nonperovskite phase. We report that lattice strain locks Rb ions into the α-phase of the lattice of a triple ...

p-NiO/LiNiO-GaN heterojunctions: a potential alternative to p-GaN for advanced devices

Elison de Nazareth Matioli, Mounir Driss Mensi, Zheng Hao, Alessandro Floriduz

In this work, we introduce a p-NiO/LiNiO stack grown via low-temperature deposition processes, offering an effective alternative for creating localized p-type regions in GaN devices. This stack combines a high hole concentration p-NiO film ([h] = 2 × 1019 ...

Selective light olefin synthesis with high ethylene abundance via CO2 hydrogenation over (Ga-In)2O3/SSZ-13 catalysts

Andreas Züttel, Mounir Driss Mensi, Laura Piveteau

Direct light olefin synthesis from CO2 hydrogenation is a new pathway to decarbonize the chemical industry. Inspired by the promising catalytic activity of Ga2O3-based catalysts in alkane dehydrogenation, this study reveals that optimizing Ga content in th ...

Solvation Structure Engineering of Weakly Coordinating Sulfonamide Electrolytes for 4.6 V Lithium Metal Batteries

Mounir Driss Mensi

A series of trifluoromethanesulfonamide solvents were synthesized with systematically controlled ring size (4-6) at the N-terminal to tune their steric and electronic properties to realize enhanced contact ion pairs for the formation of an anion-derived so ...
