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 …

Layered rhenium sulfide on free-standing three-dimensional electrodes is highly catalytic for the hydrogen evolution reaction: Experimental and theoretical study

Hydrogen evolution reaction is the key for clean energy utilization. Recently, molybdenum disulfide (MoS2) was suggested as a replacement for the most efficient catalyst to date for such reaction, which is platinum. We show here that electrodes based on layered rhenium sulfide (ReS2) catalyst show dramatic improvement when compared to MoS2. We have shown by …
