Turn Lemons into Lemonade : Increasing the Mxene Capacity by Controlled Oxidation in Air

Supramolecular Engineering of Ti3C2Tx MXene ‐Perylene Diimide Hybrid Electrodes for the Pseudocapacitive Electrochemical Storage of Calcium Ions

“…[19,20] However, Ti 3 C 2 T x exhibits capacitive-type charge storage behavior in neutral aqueous electrolytes, thus limiting charge storage capacities below 20 mAh g −1 . [20,21] MXene-based hybrid materials such as MXene@MOFs, [22,23] MXene@metal oxides [24,25] and MXene@organic materials [26][27][28] were explored for a variety of electrochemical energy storage applications. Most importantly, the top-down wet chemical etching process introduces negative surface charges and heterogeneous surface functionality (-OH, -O, -F, and -Cl) to MXenes, which may be exploited for the development of Ti 3 C 2 T x based hybrid electrodes via ionic and hydrogen-bonding interactions.…”
