Titanium carbide (Ti2C) is a novel two-dimensional (2D) MXene material with a face-centered cubic crystal structure. Ti2C MXene has a high melting point, corrosion resistance, and chemical inertness, as well as excellent electrical conductivity. Ti2C is a material that is extensively utilized in the production of wear-resistant materials and cutting tools.
Alfa Chemistry specializes in 2D nanomaterials technology companies, mainly dealing in MXenes and MAX phase materials, black phosphorus, etc. Our R&D team is led by a group of PhDs with international study and years of research experience. We can "personalize" our Ti2C MXene solutions to meet the needs of our customers' applications. Contact us today to assist you in solving your application problems quickly.
Titanium Carbide Solution Synthesis and Characterization
Alfa Chemistry customizes Ti2C flake solutions in different media. We produce high quality T2C flakes dispersed in different media by acid treatment and pulsed sonication of high quality Ti2C crystals. To prepare monolayers of Ti2C MXene, we treat the raw MXene material using a NaF-HCl solution etching process. The whole process starts with the precursor Ti2AlC and ends with Ti2C after the pulsed NaF-HCl etching process.

The Ti2AlC powder was gently added to an etching solution including NaF and HCl and maintained at 60 °C for 24 hours under magnetic stirring. To obtain multilayer Ti2C sheets, the combined solution was washed multiple times with HCl, followed by washing with water to a pH more than 6 in the supernatant. The multilayer Ti2C sheets were mechanically agitated at room temperature for 18 hours with dimethyl sulfoxide (DMSO). To eliminate the DMSO, the solution was rinsed with water and centrifuged multiple times. With ultrasonic stirring, the Ti2C MXene was submerged in the medium for 6 hours.
Finally, a monolayer Ti2C MXene solution was obtained by centrifugation. We pay special attention to reducing the etch rate and eliminating the secondary MAX phase to achieve 100% purity, perfect layering and greater than 99.999% purity.
Due to its environmental stability, dispersibility and non-polluting nature, we use ethanol as the dispersant solvent by default. Depending on your requirements, we can also produce Ti2C MXene dispersions in various forms such as ethanol, isopropanol, deionized water and NMP. if your research requires the use of other media, please write a note in your inquiry regarding the type of solution you require.

The structure, chemical composition, crystallinity, composition and surface terminations of Ti2C flakes have been confirmed by scanning electron microscopy (SEM) images, high resolution transmission electron microscopy (HRTEM) images, electron energy dispersive spectroscopy (EDAX), Raman spectroscopy and radio photoelectron spectroscopy (XPS) measurements.
Note
To reduce shipping costs, we mainly ship supersaturated 2D solutions, the concentration of which depends specifically on the type of 2D layer. The supersaturated solution can be diluted into a large amount after the customer gets it. The customer can then deposit the 2D layer onto the desired substrate by a simple rotary casting process.
