Vanadium Carbide Solution Customization

Alfa Chemistry works with MXenes and MAX phase materials, black phosphorus, and other two-dimensional (2D) nanomaterials. MXene are transition metal carbide and/or nitride nanosheets with good electrical conductivity and tunable transition metal oxide-like surface terminations that can undergo redox reactions. 2D Vanadium carbide (V2C MXene) is the lightest of them all, and vanadium surface layers have the potential to reach pseudocapacitive behavior.

Alfa Chemistry can "personalize" V2C MXene solutions to meet the needs of our customers' applications. Our R&D team is led by a group of PhDs with international study and years of research experience. Contact us today to assist you in solving your application problems quickly.

Manganese Dioxide Synthesis and Characterization

V2C MXenes have numerous uses in a variety of sectors. V2C MXene performs better as an anode for LIBs than many other MXenes; V2C MXene can also be utilized as an anode for sodium-ion capacitors and produces good results. Furthermore, metal-modified V2C MXene has been discovered to have extremely high catalytic activity for hydrogen precipitation reactions (HER), opening up new possibilities as a low-cost alternative to the precious metal Pt.

Manganese Dioxide Synthesis and Characterization

V2C MXene flakes are used in Alfa Chemistry's bespoke solutions. Pulsed sonication and acid treatment of high-quality V2C crystals manufactured in advance produce high-quality V2C flakes dispersed in solution, resulting in V2C solutions. Because of its environmental stability, dispersing properties, and non-polluting nature, we utilize ethanol as a dispersant solvent by default. Depending on your needs, we can also make several forms of V2C MXene dispersions, such as ethanol, isopropanol, deionized water, and NMP. If your research necessitates the use of other solvents, please include them in the RFQ.

Custom solutions are stable under ambient conditions and can be easily deposited on any substrate or surface. The lateral dimensions of V2C flakes deposited on various substrates range from 10 nm to 5 m, with thicknesses ranging from 1 L to several layers and multilayers. Scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), electron energy dispersive spectroscopy (EDAX), Raman spectroscopy, and radio photoelectron spectroscopy have all been used to examine V2C flakes (XPS).

V2C MXene crystals were synthesized by etching at 90°C using a sodium fluoride/hydrochloric acid (NaF-HCl) solution. Special care was taken to reduce the etching rate and eliminate the secondary MAX phase to achieve 100% purity, perfect delamination, and purity above 99.999%. The process starts with the precursor V2AlC and ends with V2C after a pulsed NaF-HCl etching process.

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.
