Application

Nb4AlC3 is the MAX phase precursor used for synthesis of Nb4C3Tx MXene, which have the below properties:

  • Electrical Conductivity: Single-layer Nb4C3Tx flakes boast an electrical conductivity of 1,024 ± 165 S cm−1.
  • Breakdown Current Density: ∼1.1 × 108 A.cm−2, comparable to Ti3C2Tx and graphene.
  • Electrochemical Performance: Specific capacity increases from 116 to 320 mAh.g−1 after 1,000 cycles at 1 A current density.
  • Interlayer Spacing: Accommodates ion intercalation/deintercalation without structural damage.
Unlock the potential of Nb4C3Tx MXene, using our Nb4AlC3 MAX precursor:
  • Electrochemical sensing: Nb4C3Tx excels in electrochemical sensing, detecting dopamine at 23 nm due to its high conductivity and enhanced intercalation.
  • Supercapacitors and Advanced batteries: Superior conductivity and charge-discharge rates for extended operation.
  • HER Catalyst: Efficient hydrogen evolution reactions.
  • ROS Scavengers: Biocompatible and photothermally stable for biomedical use.
