Summary:[Display omitted] •A novel strategy is presented for hydrogen sensing.•The composite has an excellent hydrogen sensing performance.•Ti3C2Tx based materials for hydrogen detection has been barely reported. Safety use of hydrogen leads to the development of highly sensitive materials for hydrogen sensing. Herein, Pd(II)@alkyne-PVA/d-Ti3C2Tx composite was prepared by spin-coating Pd(II)@alkyne-PVA solution onto the filter membrane supported with delaminated Ti3C2Tx (d-Ti3C2Tx). The properties of the composite were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectroscopy, and X-ray photoelectron spectroscopy (XPS). The results demonstrate that the composite shows high sensitivity and stability for hydrogen sensing.
