Özet

In this study, a palladium-doped cryo-MXene catalyst was prepared by a wet impregnation method and its catalytic activity was studied using the hydrolysis of methylamine-borane. The palladium nanoparticles were doped on the surface of the MXene substrate by chemical reduction of Pd+2 and characterized by different analysis techniques. The prepared palladium-doped MXene phases were cryogenically treated with liquid nitrogen at −160 °C. The morphological and structural characterization of particles was performed using a field emission scanning electron microscope, transmission electron microscope, and X-ray diffraction machine with Cu Kα radiation. The surface and bonding types of particles were determined by X-ray photoelectron spectroscopy. The palladium-doped cryo-MXene catalysts exhibited excellent catalytic performance in the hydrolysis of methylamine-borane with a turnover frequency (TOF) of 45.8 for 298 K. In addition, the palladium-doped cryo-MXene displayed good stability even after the five cycles.
