Abstract

We investigate the formaldehyde gas sensing properties of poly(5,6,7,8-tetrahydro-1-naphthylamine)-intercalated MoO₃ thin films ((PTHNA)_xMoO₃). The resistance responses of (PTHNA) _xMoO₃ to formaldehyde increase with increasing intercalation temperature. X-ray photoelectron spectroscopy reveals that the molar ratio of Mo⁵⁺ decreases with increasing intercalation temperature.
