Abstract

Abstract: For the first time, a series of highly efficient RhNiP@MOF-74 nanocomposite catalysts were synthesized by a one-step reduction process, subsequently characterized by inductively coupled plasma atomic emission spectroscopy (ICP-AES), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS). Synergistic electronic effects between Rh, Ni, and P, along with electron transfer phenomena between RhNiP and MOF-74 resulted in outstanding catalytic activities towards the dehydrogenation of hydrous hydrazine in an alkaline solution (2 M NaOH) at 50 °C. The turnover frequency (TOF) value of Rh47 Ni18 P35 @MOF-74 reached 715.4 mol H2 ·h −1 (mol metal) −1 with 100% hydrogen selectivity, and there was no significant decrease even after five cycles. Highlights: The Rh47 Ni18 P35 @MOF-74 catalyst exhibits an outstanding catalytic activity. Its TOF value is 715 mol H2 ·h −1 (mol metal) −1, and 100% H2 selectivity. The durability of the catalyst is excellent after five cycles.
