MXene/Bi2O3 Nanocomposites as Supercapacitors for Portable Electronic Devices

2D MXene nanosheets often encounter challenges such as aggregation and restacking, which can significantly decrease their performance in supercapacitor applications. Herein, we prepared the Bi2O3 nanoflowers decorated MXene electrode via the coprecipitation method. The insertion of Bi2O3 nanoflowers over the MXene nanosheet not only effectively resolves the restacking challenge of the MXene nanosheet but also …

High-entropy alloys: Electrochemical Nanoarchitectonics toward high-performance Water splitting

High-entropy alloys (HEAs) offer unprecedented catalytic properties over single-composition nanoparticles or single atom engineered materials. Traditionally, the Hume–Rothery rule suggests that only size-and-structure similar elements can be mixed in conventional alloying, which limits the possible combinations of alloying elements. Here we propose an electrochemical approach as an innovative and alternative synthetic method for preparation of …
