Title: Understanding Functionalization of Titanium Carbide (MXene) with Quinones and Their Pseudocapacitance

Abstract

In this work, the interaction mechanism of 1-aminoanthraquinone (AQ) on Ti₃C₂T_x MXene by noncovalent (AQ@Ti₃C₂T_x) and covalent (AQ-Ti₃C₂T_x) functionalization is reported. Spectroscopic, X-ray, and scattering techniques confirmed noncovalent functionalization of AQ on Ti₃C₂T_x MXene without its catalytic decomposition, resulting in intercalation and interaction of AQ with Ti₃C₂T_x MXene. Diazonium reaction was further used to covalently functionalize AQ molecules on Ti₃C₂T_x MXene. Optimized AQ-Ti₃C₂T_x freestanding electrodes of ~44 μm thickness delivered capacitance of ~300 F/g and improved rate performance compared to the pristine counterpart (Ti₃C₂T_x) due to carbonyl redox of AQ and improved ionic transport between MXene layers due to pillaring of AQ molecules.

Effect of glycine functionalization of 2D titanium carbide (MXene) on charge storage

Journal Article Chen, Chi ; Boota, Muhammad ; Urbankowski, Patrick ; ... - Journal of Materials Chemistry. A

Restacking of two-dimensional (2D) flakes reduces the accessibility of electrolyte ions and is a problem in energy storage and other applications. Organic molecules can be used to prevent restacking and keep the interlayer space open. In this paper, we report on a combined theoretical and experimental investigation of the interaction between 2D titanium carbide (MXene), Ti₃C₂T_x, and glycine. From first principle calculations, we presented the functionalization of glycine on the Ti₃C₂O₂ surface, evidenced by the shared electrons between Ti and N atoms. To experimentally validate our predictions, we synthesized flexible freestanding films of Ti₃C₂T_x/glycine hybrids. X-ray diffraction and X-ray photoelectronmore »« less

Surface Redox Pseudocapacitance of Partially Oxidized Titanium Carbide MXene in Water-in-Salt Electrolyte

Journal Article Wang, Xuehang ; Bak, Seong-Min ; Han, Meikang ; ... - ACS Energy Letters

Achieving pseudocapacitive intercalation in MXenes with neutral aqueous electrolytes and driving reversible redox reactions is scientifically appealing and practically useful. Here, we report that the partial oxidation of MXene intensifies pseudocapacitive Li⁺ intercalation into Ti₃C₂T_x MXene from neutral water-in-salt electrolytes. An in situ X-ray absorption near-edge structure analysis shows that the Ti oxidation state changes during the Li+ intercalation, indicating the presence of a surface redox reaction. The Ti oxidation/reduction is further confirmed by an in situ extended X-ray absorption fine structure analysis, which shows a reversible contraction/expansion of the Ti–C interatomic distance. The intensified Li⁺ pseudocapacitive intercalation can bemore »« less

Influence of metal ions intercalation on the vibrational dynamics of water confined between MXene layers

Journal Article Osti, Naresh C. ; Naguib, Michael ; Ganeshan, Karthik ; ... - Physical Review Materials

Two-dimensional carbides and nitrides of early transition metals (MXenes) combine high conductivity with hydrophilic surfaces, which make them promising for energy storage, electrocatalysis, and water desalination. Effects of intercalated metal ions on the vibrational states of water confined in Ti₃C₂T_x MXenes have been explored using inelastic neutron scattering (INS) and molecular dynamics simulations to better understand the mechanisms that control MXenes’ behavior in aqueous electrolytes, water purification and other important applications. Here, we observe INS signal from water in all samples, pristine and with lithium, sodium or potassium ions intercalated between the 2D Ti₃C₂T_x layers. However, only a small amountmore »« less

The effect of hydrazine intercalation on the structure and capacitance of 2D titanium carbide (MXene)

Journal Article Mashtalir, O. ; Lukatskaya, Maria R. ; Kolesnikov, Alexander I. ; ... - Nanoscale

Herein we show that hydrazine intercalation into 2D titanium carbide (Ti₃C₂-based MXene) results in changes in its surface chemistry by decreasing the amounts of fluorine, OH surface groups and intercalated water. It also creates a pillaring effect between Ti₃C₂T_x layers pre-opening the structure and improving the accessability to active sites. Furthermore, the hydrazine treated material has demonstrated a greatly improved capacitance of 250 F g^–1 in acidic electrolytes with an excellent cycling ability for electrodes as thick as 75 μm.

Nanoscale elastic changes in 2D Ti₃C₂T_x (MXene) pseudocapacitive electrodes

Journal Article Come, Jeremy ; Xie, Yu ; Naguib, Michael ; ... - Advanced Energy Materials

Designing sustainable electrodes for next generation energy storage devices relies on the understanding of their fundamental properties at the nanoscale, including the comprehension of ions insertion into the electrode and their interactions with the active material. One consequence of ion storage is the change in the electrode volume resulting in mechanical strain and stress that can strongly affect the cycle life. Therefore, it is important to understand the changes of dimensions and mechanical properties occurring during electrochemical reactions. While the characterization of mechanical properties via macroscopic measurements is well documented, in-situ characterization of their evolution has never been achieved atmore »« less
