Nb4C3Tx MXene Phase Powder Description
Nb4C3Tx MXene phase powder is a two-dimensional transition metal carbide material synthesized through the selective etching of aluminum from the parent Nb4AlC3 MAX phase using fluoride-containing solutions, which simultaneously generates surface functional groups denoted as Tx (typically -O, -OH, and -F). This process yields a multilayered powder with an accordion-like morphology, characterized by high metallic conductivity, excellent hydrophilicity facilitating dispersion in aqueous media, and a high specific surface area when delaminated. Its combination of electrical, mechanical, and surface properties makes it a promising candidate for advanced applications including high-performance electrodes in lithium-ion and sodium-ion batteries, supercapacitors, effective electromagnetic interference (EMI) shielding composites, sensitive chemical sensors for gas detection, and as a catalyst or support in various electrochemical reactions. The material’s performance is highly dependent on etching parameters, intercalation, and delamination processes, which control its layer separation, defect density, and termination group composition.
