Fe–N–C Electrocatalyst and Its Electrode: Are We Talking about the Same Material?
نویسندگان
چکیده
Evaluation of the electrocatalyst performance data includes an electrode preparation step. Herein, we compare structural composition Fe–N–C materials, used to electrocatalyze oxygen reduction reaction in proton-exchange membrane fuel cells, before and after catalyst layer preparation. The effects this step on electronic structure local coordination Fe were investigated by X-ray absorption (XAS) emission spectroscopies (XES), for materials prepared via different synthetic routes. This work underlines importance determining further studies structure–activity–stability correlations.

Health System Resilience: What Are We Talking About? A Scoping Review Mapping Characteristics and Keywords
Background Health systems are based on 6 functions that need to work together at all times to effectively deliver safe and quality health services. These functions are vulnerable to shocks and changes; if a health system is unable to withstand the pressure from a shock, it may cease to function or collapse. The concept of resilience has been introduced with the goal of strengthening healt...
