“…Since the N atom forms polar covalent bonds with the H atom and is easily adsorbed to the Ti 3 C 2 surface, the characteristic peaks near 3130 and 3109 cm −1 are the N-H vibrational peaks of the bonding, the vibrational peaks at 1350–1550 cm −1 can be attributed to the vibrational stretching of -CH 3 and the C-N stretching vibrational peaks in the urea molecule, and the characteristic peaks near 580 cm −1 corresponds to the stretching vibration of Ti-C. The presence of these functional groups can promote electron transfer and enhance electrical conductivity, while the doping of N atoms can effectively improve the electron transport network and ion transport channels of Ti 3 C 2 MXene materials [ 41 ].…”

Methyl orange dye (MO) is one of the azo dyes, which is not only difficult to degrade but also hazardous to human health, therefore, it is necessary to develop an efficient photocatalyst to degrade MO. In this paper, a facile and low-cost elemental doping method was used for the surface modification of Ti3C2 MXene, i.e., nitrogen-doped titanium carbide was used as the nitrogen source, and the strategy of combining solvent heat treatment with non-in situ nitrogen doping was used to prepare N-Ti3C2 MXene two-dimensional nanomaterials with high catalytic activity. It was found that the catalytic efficiency of N-Ti3C2 MXene materials was enhanced and improved compared to the non-doped Ti3C2 MXene. In particular, N-Ti3C2 1:8 MXene showed the best photo-catalytic ability, as demonstrated by the fact that the N-Ti3C2 1:8 MXene material successfully degraded 98.73% of MO (20 mg/L) under UV lamp irradiation for 20 min, and its catalytic efficiency was about ten times that of Ti3C2 MXene, and the N-Ti3C2 photo-catalyst still showed good stability after four cycles. This work shows a simplified method for solvent heat-treating non-in situ nitrogen-doped Ti3C2 MXene, and also elaborates on the photo-catalytic mechanism of N-Ti3C2 MXene, showing that the high photo-catalytic effect of N-Ti3C2 MXene is due to the synergistic effect of its efficient charge transfer and surface-rich moieties. Therefore, N-Ti3C2 MXene has a good prospect as a photo-catalyst in the photocatalytic degradation of organic pollutants.

“…In recent times, MXenes have piqued greater recognition from the scientific community due to their excellent conductivity, 1,2 good hydrophilicity 3 and a good surface area with a larger negative potential on the surface. 4 MXenes are obtained from MAX (M n+1 AX n ) (n = 1−3) phases by etching "A" layers selectively. "M" can be any transition metal, "A" represents group 14 or 14 elements, and "X" refers to the surface termination groups.…”

The unrivaled depth of the energy crisis has imposed a critical challenge to appraise the existing innovations in energy storage devices. Supercapacitors lag behind in terms of energy density, on par with batteries, which has led to the development of hybrid capacitors exhibiting improved energy density. Despite possessing good physiochemical properties proportionate to Ti 3 C 2 T x MXene, Ti 2 CT x has been less explored. In this study, we exploited the theoretical aspects of Ti 2 CT x to elucidate its potential as a promising supercapacitor device. Further, to improve the performance and stability of Ti 2 CT x , we have coupled it with a Co−Al−Mn layered double hydroxide (LDH) via a facile ultrasonication approach. The electrochemical parameters of Co−Al−Mn LDH@Ti 2 CT x were assessed in a redox additive electrolyte, viz., potassium hydroxide and potassium ferricyanide (6 M KOH + 0.01 M K 3 [Fe(CN) 6 ]). The addition of Fe(CN) 6 3− ameliorates the performance due to the arousal of the redox couple during the charging and discharging of the supercapacitor device. A redox mechanism has been proposed to highlight the improvement of the performance when a redox additive is used. The Co− Al−Mn LDH@Ti 2 CT x electrode displays a specific capacitance value of 221 F/g at 5 mVs −1 . A solid-state flexible device was constructed with a PVA/KOH gel electrolyte, which exhibited good stability despite twisting the electrode at various bending angles. To elucidate the practicability of the constructed device, a red LED light was illuminated using three electrodes arranged in series.
