Novel Phosphazenium Tetrafluoroborate Dopant Enables Efficient and Thermally Stable n‐Doped Organic Semiconductors

open access: yesAdvanced Electronic Materials, EarlyView.
A novel n‐dopant, phosphazenium tetrafluoroborate (P2BF4), is introduced for efficient n‐doping in N2200, P(PzDPP‐CT2) and other organic semiconductors (OSCs). P2BF4‐doped OSC films exhibit exceptional thermal stability, maintaining electrical conductivity after heating at > 150 °C for 24 h. This stability allows organic thermoelectric devices based on

Challenges in Elucidating the Free Energy Scheme of the Laccase Catalyzed Reduction of Oxygen

open access: yesChemCatChem, Volume 15, Issue 1, January 9, 2023., 2023
Bioinorganic chemistry: High potential variants of the multicopper enzyme laccase have a remarkably low overpotential for the oxygen reduction reaction (ORR). Understanding the precise underlying principles are potentially of great value in light of the energy transition wherein the ORR plays a crucial role.

Designer Electrocatalysts for the Oxygen Reduction Reaction with Controlled Platinum Nanoparticle Locality

open access: yesAdvanced Energy Materials, EarlyView.
Pt/C catalysts differing only in the locality of the Pt nanoparticles, whether inside or outside of the pores of the same carbon support, are needed to study the effect of said locality. Depending on the carbon support used, nanoparticles inside the pores can show hindered accessibility and ORR performance.

Thermocatalytic Ammonia Decomposition – Status and Current Research Demands for a Carbon‐Free Hydrogen Fuel Technology

open access: yesChemCatChem, Volume 15, Issue 2, January 20, 2023., 2023
Ammonia Decomposition for a Carbon‐Free Hydrogen Fuel Technology: Ammonia is a promising example of an efficient and transportable hydrogen carrier. The thermocatalytic decomposition of ammonia can be used to produce COx‐free hydrogen on demand. Thorough research into this process and the development of active catalyst materials are seen as the ...
