Abstract

Time and again, SBA-15-based composites as mesoporous materials and incorporating transition metals in them have been attracting dramatic attention in the field of catalysis due to their remarkable features. In this paper, the activity of SBA-15 supported ionic liquid-Pd(II) has been investigated in the catalytic transfer hydrogenation of nitroarenes with formic acid as a hydrogen donor at room temperature in water medium and oxidation of benzyl alcohols to benzaldehyde derivatives under atmospheric oxygen at high temperature. This novel nanocatalyst was characterized by FT-IR, SA-XRD, BET, BJH, TGA, FE-SEM, TEM, and ICP as most commonplace techniques for analyzing its characteristics to be revealed truth. Furthermore, the EDX analysis illustrates the grafting of ionic liquid-Pd(II) into SBA-15. The catalyst showed high stability in reaction conditions and can be recovered and reused for at least 15 and 6 reaction runs in oxidation and reduction reactions, respectively.
