Synthesis and DFT study of NH2-MOF235(Fe)-derived ZnFe2O4–Fe2O3–ZnO multiple heterojunction nanocomposites for triethylamine gas detection

This work designs a ZnFe 2 O 4 –Fe 2 O 3 –ZnO multiple heterojunctions from NH 2 -MOF235(Fe)@MOF5 for TEA sensing. The sensor exhibits excellent properties including high sensitivity, fast response, low detection limit, supported by DFT calculations.
