Structural and morphological analysis for cerium (Ce +3) doped intercalated 2D MXene

Room-temperature synthesis of 2D-Ti3C2Tx nano-sheets by organic base treatment

“…7 The Ti 3 C 2 Tx phase is the most studied among MXenes known for its 2D nature, metallic conductivity, and hydrophilicity, and it can be obtained by extracting aluminum from the MAX Ti 3 AlC 2 phase. 8 The flake size, structure, and electronic properties of MXenes can depend on the different etchants used for exfoliation (NaF + HCl, HF, LiF + HCl, etc.) and on the intercalation conditions.…”

Microwave-assisted rapid synthesis of titanium phosphate free phosphorus doped Ti3C2 MXene with boosted pseudocapacitance

“…Heteroatom doping is one of the effective and simple techniques for structural and compositional modifications to tune the electronic and electrochemical properties of various 2D materials, 12–18 including MXenes. 4,19–23 Among the heteroatoms, nitrogen (N), 24 boron (B), 25 niobium (Nb), 26 tellurium (Te), 27 and vanadium (V) 28 are some popular dopants that have been doped in various MXenes for the improvement of their energy storage and generation performance, in recent times. For instance, N doped Ti 3 C 2 T x (N-Ti 3 C 2 ) 29 has been developed through solvothermal treatment, where ex situ nitrogen doping was carried out using urea in saturated ethyl alcohol as the N source to register high volumetric capacitance, while operating as a supercapacitor electrode in a potential window of 0.7 V. In another study, to demonstrate the practical application, crumpled N-Ti 3 C 2 nanosheets 24 were obtained via heating for the construction of printable electrochemical energy storage devices to operate in a potential window of 0.6 V in 3 M H 2 SO 4 , which generates an areal capacitance of 70.1 mF cm −2 at 10 mV s −1 .…”
