Acetonitrile solutions of Cu(tmby)22+ exhibit aging-dependent changes of UV–Vis spectra, which were attributed to partial reduction to Cu(tmby)2+. This effect is boosted by the addition of imidazole bases, i.e., N-methyl-benzimidazole (NMB) or 5‑chloro-1-e ...
In situ investigation of the surface composition of catalyst particles improves the understanding of the active species in heterogeneous catalysis. This study analyzed the surface chemistry of ruthenium nanoparticles supported on alumina during CO2 methana ...
Perovskite solar cells (PSCs) with ammonium passivation exhibit superior device performance and stability. Beyond typical chemical passivation, ammonium salts control the electronic structure of perovskite surfaces, yet the molecular structure-property rel ...
In conventional n-i-p perovskite solar cells, unsolved issues persist, particularly concerning notorious performance degradation under prolonged heat exposure at 85°C. By reducing the concentration of 4-tert-butylpyridine (tBP) and lithium bis(trifluoromet ...
CO2 electrolysis is a promising process to produce synthetic and carbon-neutral chemicals. Zero-gap CO2 electrolyzers featuring a forward bias bipolar membrane (BPM) solve problems like salt precipitation and CO2 crossover but still suffer from limited per ...
The OER involves a four-electron transfer and is a kinetically sluggish reaction that requires additional potential to drive. To enhance the electrochemical performance of the above-mentioned applications, highly efficient, corrosion-resistant, earth-abund ...
A new concept based on Power Plant Units, able to deliver renewable energy on demand, for the transition from fossil fuels to renewable energy in Switzerland is presented. The technically realized efficiencies showed that complete electrification leads to ...
This article aims to present the redox aspects of lithium-ion batteries both from a thermodynamic and from a conductivity viewpoint. We first recall the basic definitions of the electrochemical potential of the electron, and of the Fermi level for a redox ...
Due to their high structural tunability, remarkable internal surface areas, readily accessible pore space, and host of possible applications, covalent organic frameworks (COFs) remain at the forefront of materials science research. Unfortunately, many COFs ...
