Selective hydrogenation of anisole over Pt/SBA-15 catalysts: Effect of Pt loading on catalytic efficiency

Year: 2025

Type: article

Abstract: Pt catalysts (0.1–2 wt.% of platinum) supported on SBA-15 were used for the selective hydrogenation of the aromatic ring of anisole with the formation of cyclohexyl methyl ether product. The catalysts were characterized by N2 physisorption, UV–vis diffuse reflectance spectroscopy, powder X-ray diffraction, and scanning and transmission electron microscopies. The reaction progress and the impact of Pt loading in the catalysts were analyzed by gas chromatography. All the catalysts demonstrated high catalytic activity for the hydrogenation of anisole to cyclohexyl methyl ether (CME), reaching 90–98% anisole conversion at 6-h reaction time with near 90% selectivity to CME (280 °C, 6.9 MPa total pressure). An increase in the Pt content led to a slight decrease in the selectivity to CME due to its transformation to cyclohexane. 1%Pt/SBA-15 catalyst was tested in three repeated catalytic cycles showing high stability and preservation of Pt nanoparticle dispersion.
