摘要：Hydrogen sensing with a fast response at room temperature is still a challenge. In this study, a novel Pt=Pd/Ti3C2TX hydrogen sensor was prepared by a straightforward hydrothermal chemical reduction method. The Pt=Pd/Ti3C2TX was characterized by X-ray diffraction, transmission electron microscope, and X-ray photoelectron spectroscopy. The experimental results showed that the response of the Pt=Pd/Ti3C2TX sensor was 24.6% and the response/recovery time was 6/8 s in the case of 200 ppm hydrogen at room temperature. The Pt=Pd/Ti3C2TX sensor could detect the hydrogen concentration as low as 1 ppm. Besides, the Pt=Pd/Ti3C2TX sensor exhibited good linearity, long-term stability, good repeatability, and high selectivity. The Pt=Pd/Ti3C2TX sensor has great potential in the field of hydrogen energy. ? 2023 Hydrogen Energy Publications LLC
