Schiff Base Complex Method for the Preparation of Fullerene-Based Ni Nanocatalyst Used in the Hydrogenation of Benzene in Gasoline

Abstract

A novel Schiff base complex method was used to prepare fullerene based Ni nanocatalyst, which is used in the hydrogenation of benzene. In this method, the functionalized fullerene with primary amine was reacted with ion of nickel and salicylaldehyde. The Schiff-base complex was formed in the presence of metal ion in order to obtain the corresponding metal complex. The nickel(II) complex on C 60 shows significantly higher catalytic activity (20%) compared to the nickel bulk. Response surface methodology was also used to examine the cumulative effect of the various parameters namely, pressure, temperature, and time; thus, they were optimized to maximize the hydrogenation of benzene to cyclohexane. The optimized model predicted that the hydrogenation yield should remain maximum (very close to 100%) at reaction temperature of 150 C, reaction time of 180 min, and hydrogen pressure of 22.33 atm.

Chemoselective reduction of quinoline over Rh–C60 nanocatalysts

“…31,32 The same methodology has been used to obtain other metal NP. 33 Also, fullerene C60 based catalysts with other metals have been described, 34 including Pd, 35 Ni 36 and Ru. 37,38 With the ability of fullerene to accommodate various metals, 39 as well as, the effectiveness of the organometallic approach to produce almost any kind of noble metal NP, we decided to synthesize Rh-C60 catalysts with the aim to produce electron-poor Rh NP, which can be very interesting for selective quinoline hydrogenation.…”
