Platinum Nanoparticles‐Decorated Ti <sub>3</sub> C <sub>2</sub> T <sub> <i>x</i> </sub> @TiO <sub>2</sub> Composite for Ammonia Sensing at Room Temperature
Herein, a platinum nanoparticles (Pt NPs)‐decorated Ti 3 C 2 T x @TiO 2 composite is synthesized for ammonia (NH 3 ) sensing at room temperature. The Ti 3 C 2 T x @TiO 2 composite is first synthesized via a hydrothermal method, in which the Ti 3 C 2 T x ‐to‐TiO 2 ratio is optimized by controlling the hydrothermal reaction time. Then, the Pt NPs functionalization is performed on the Ti 3 C 2 T x @TiO 2 composite obtained under optimal hydrothermal time to further improve the NH 3 response. At room temperature, the sensor based on Pt‐decorated Ti 3 C 2 T x @TiO 2 exhibits a high response to NH 3 (13% at 5 ppm), whereas the pristine Ti 3 C 2 T x shows negligible response even at 100 ppm NH 3 .
