Then the catalyst Ni@Zn-MOCP (7.5 wt% Ni) was successfully prepared via a wet impregnation strategy employing Ni(acac)2 (acac=acetylacetonate) as the precursor. The hydrogenation of crotonaldehyde was utilized as the probe reaction to explore its catalytic activity. The samples were characterized by powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR), N2 adsorption-desorption measurements, X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). PXRD patterns of Ni@Zn-MOCP showed good coincidence with that of Zn-MOCP, and the pore texture of Zn-MOCP was still maintained after impregnation. Most of Ni(acac)2 over Zn-MOCP were reduced to Ni0 after reduction based on XPS analysis. In terms of the turnover of frequency (TOF) of crotonaldehyde, Ni@Zn-MOCP (53.6h−1) exhibited much higher activity than the industrial catalyst Ni/SiO2 (29.5h−1). Furthermore, the reusability of the catalyst Ni@Zn-MOCP over the hydrogenation for crotonaldehyde was tested.
