Understanding the behavior of high-entropy carbides (HECs) under oxygen-containing environments is particular importance for their promising applications in structural components, catalysis, and energy-related fields. Herein, evolution (Ta, Ti, Cr, Nb)C (HEC-1) nanoparticles (NPs) tracked situ during oxidation at atomic scale by using an open-cell environmental aberration-corrected scanning transmission electron microscope. Three key stages are clearly discerned HEC-1 NPs level below 900 °C: i) increased amorphization from 300 to 500 °C due energetically favorable formation carbon vacancies substitution with oxygen atoms; ii) nucleation subsequent growth locally ordered nanocluster intermediates within generated amorphous oxides 800 °C; iii) final one-step crystallization non-equimolar MeO

Abstract This study investigates the performance of high entropy alloys [Fe 3 Cr Mn 2 NiV, HEA)] and oxides [(Fe NiV)O 4 , HEO)] as electrode materials for supercapacitors. HEA is synthesized through mechanical alloying, followed by HEO forming via an oxidation process. XRD results demonstrate comprises both amorphous crystalline phases, whereas has entirely structure. SEM analyses showed exhibits larger irregular particles, displays a smaller spherical morphology. EPR revealed significant changes in defect structures unpaired electron configurations during transition from to HEO. prone diffusion‐controlled processes due their regular structure strong magnetic interactions; however, capacitive behavior based on surface redox reactions pseudo‐capacitive mechanisms oxygen vacancies. CV that contributes more reactions, while GCPL suggested demonstrated superior energy density (40.8 Wh kg −1 ) power (14.3 kW ). Impedance exhibited reduced internal resistance enhanced ion conductivity, higher processes. In conclusion, exhibit distinct storage mechanisms, these can be optimized supercapacitor applications.
