The Fe uptake influence on Ni-MOF-74 derived oxygen evolution electrocatalysts is studied bridging operando XAS studies with implementation in AEM-WE.
ABSTRACT Metal organic frameworks (MOFs) have a promising perspective as oxygen evolution reaction (OER) electrocatalysts due to their high surface areas and tunable structures. However, one of the main challenges for further application is inferior stability during alkaline OER. Herein, operando x‐ray absorption spectroscopy diffraction NiCo‐MOF‐74 materials unveil electrochemical transformations differentiating between electrolyte‐induced, beam‐induced, electrochemically induced changes...
The paper contains the study of sharp extensions weak-type estimates for a martingale maximal function. Given 1<p<∞ and pair (x,y) nonnegative numbers satisfying xp≤y, we identify optimal upper bounds ‖|supnfn|‖p,∞, martingales f=(fn)n≥0 ‖f‖1=x ‖f‖pp=y.
