Laser-Processed 2D Germanane on Graphene for Organohydrogel-Based Zinc-Ion Hybrid Capacitors

Group 14 monoelemental two-dimensional (2D) materials beyond graphene, such as silicene and germanene, have gained significant attention in the scientific community. Covalent functionalization of germanene with hydrogen and methyl leads to germanane (hydrogen/methyl-terminated germanene; HGe/MGe). While the optical and electronic properties of HGe and MGe were explored previously, there is no report on their zinc …

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 …
