Ti2NbC2Tx MXene Phase Powder Description
Ti₂NbC₂Tₓ MXene Phase Powder is a bimetallic two-dimensional material synthesized via a precise wet chemical etching process. Derived from the Ti₂NbAlC MAX phase precursor by selectively removing the aluminum layers, this material retains a unique two-dimensional layered carbide structure, terminated by surface functional groups (denoted as Tₓ, such as -OH, -O, -F). This structure allows Ti₂NbC₂Tₓ to not only inherit the high electrical conductivity and hydrophilicity of the MXene family but also exhibit remarkable advantages in electrochemical activity and structural stability due to the atomic-level synergy between titanium and niobium.
