Efficient tuning of surface nickel species of the Ni-phyllosilicate catalyst for the hydrogenation of maleic anhydride

Efficient tuning of surface nickel species of the Ni-phyllosilicate catalyst for the hydrogenation of maleic anhydride

The rational design of catalyst is vital in the hydrogenation of maleic anhydride (MA) to chemicals, for its special construction with one C=C bond and two C=O bonds.

The acid sites adsorb and activate the C=C and C=O groups, whereas the Ni 0 facilitates the H 2 decomposition. In situ XPS demonstrated that the ratio of surface Ni 0 and Lewis acid sites can be modulated effectively by changing the Ni/Si molar ratio in the catalysts, and they exhibited significantly different catalytic activity in the hydrogenation of MA. Under a lower temperature, the hydrogenation activity of MA to SA linearly increases by increasing the Lewis acid sites surface area when the accessible Ni 0 surface area is enough, whereas it is primarily affected by the Ni 0 sites under high temperature for the hydrogenation of MA to GBL.

Abstract

The rational design of catalyst is vital in the hydrogenation of maleic anhydride (MA) to chemicals, for its special construction with one C=C bond and two C=O bonds. Herein, the catalyst with nickel nanoparticles (NPs), inlaid nickel phyllosilicate (Ni-PS) featured with proper Ni 0 and assembled Lewis acid sites, is proposed for the efficient hydrogenation of MA to succinic anhydride (SA) and γ-butyrolactone (GBL). The remarkable efficiency is attributed to the synergistic effect between the surface Ni 0 and the Lewis acid sites induced from partially reduced Ni and coordinatively unsaturated Ni(II) in Ni-PS. The acid sites adsorb and activate the C=C and C=O groups, whereas the Ni 0 facilitates the H 2 decomposition. In situ XPS demonstrated that the ratio of surface Ni 0 and Lewis acid sites can be modulated effectively by changing the Ni/Si molar ratio in the catalysts, and they exhibited significantly different catalytic activity in the hydrogenation of MA. Under a lower temperature, the hydrogenation activity of MA to SA linearly increases by increasing the Lewis acid sites surface area when the accessible Ni 0 surface area is enough, whereas it is primarily affected by the Ni 0 sites under high temperature for the hydrogenation of MA to GBL.
