Highly Selective Cleavage Dehydrogenation of BPZ for Preparation of <i>p</i>‑Phenylphenol over Efficient Pd-Cu/TiO₂ Bimetallic Catalysts.

ABSTRACT: Pd-Cu bimetallic catalysts were successfully synthesized for the dehydrogenation of Bisphenol Z (BPZ) by an impregnation-reduction method. The obtained catalyst was studied by XRD, HRTEM, XPS, BET, and NH₃-TPD techniques and effectively applied in the highly selective cleavage dehydrogenation of BPZ to give PPP > 99% yield at 270 °C and atmospheric pressure in the solvent-free condition. It was demonstrated that the "synergistic effect" of the bimetallic catalysts could effectively promote the cleavage dehydrogenation reaction. Pd species served as the primary active sites for the adsorption and dissociation of H* and the activation of C-H bonds, while the introduced Cu species accelerated the breaking process of the C-H bond. This catalyst demonstrated remarkable stability and
