Time‐Dependent Cation Selectivity of Titanium Carbide MXene in Aqueous Solution

چکیده
Electrochemical ion separation is a promising technology to recover valuable ionic species from water. Pseudocapacitive materials, especially 2D are up-and-coming electrodes for electrochemical separation. For implementation, it essential understand the interplay of intrinsic preference specific (by charge/size), kinetic mobility), and crystal structure changes. Ti3C2Tz MXene chosen here investigate its selective behavior toward alkali alkaline earth cations. Utilizing an online inductively coupled plasma system, found that shows time-dependent selectivity feature. In early stage charging (up about 50 min), K+ preferred, while ultimately Ca2+ Mg2+ uptake dominate; this unique phenomenon related dehydration energy barriers exchange effect between divalent monovalent Given wide variety MXenes, work opens door new avenue where ion-separation with can be further engineered optimized.

Two-Dimensional Titanium Carbide MXene As a Cathode Material for Hybrid Magnesium/Lithium-Ion Batteries.
As an alternative to pure lithium-ion, Li+, systems, a hybrid magnesium, Mg2+, and Li+ battery can potentially combine the high capacity, high voltage, and fast Li+ intercalation of Li-ion battery cathodes and the high capacity, low cost, and dendrite-free Mg metal anodes. Herein, we report on the use of two-dimensional titanium carbide, Ti3C2Tx (MXene), as a cathode in hybrid Mg2+/Li+ batterie...
متن کاملCombustion Synthesis of Titanium-Tungsten Carbide Composites in Iron Matrix
Combustion synthesis has been used to produce Fe-(Ti,W)C composites. A simple reactor was designed which made it possible to ignite the samples under controlled atmosphere. Samples with different W/Ti ratio were ingnited under argon atmosphere by an electric arc and a self-propagating reaction was initiated in each sample. Different composites such as WC in Fe-Ti matrix, WC+(Ti,W)C in Fe matrix...
