Designing a bifunctional catalyst with both highly selective C=O hydrogenation ability and Lewis acid-catalyzed ring-rearrangement ability is highly important for the synthesis of the cyclopentanone motifs from furfural derivatives Herein, a class of pyrochlore/Al2O3 composites (2.68 wt%Y2(Sn0.65Al0.35)2O7-δ/Al2O3, 7.74 wt%Y2(Sn0.65Al0.35)2O7-δ/Al2O3) with a onefold Lewis acidity and rich oxygen defects were synthesized via a dissolution-precipitation method. After the impregnation by Pd nanoparticles, the oxygen defect of pyrochlore/Al2O3 shows a bifunctional effect: they can adsorb C=O, promoting the selective C=O hydrogenation step and can enhance the accessibility of coordinatively unsaturated metal ions, providing Lewis acidic sites for the ring-rearrangement step. The composite-based catalysts show noticeably higher hydrogenation and hydrolysis rates than their corresponding single metal oxide-based catalysts (Pd/Al2O3, Pd/Y2Sn2O7). Finally, 7.74 wt%Y2(Sn0.65Al0.35)2O7-δ/Al2O3 shows a cyclopentanone yield of 98.1% and a 3-hydroxymethyl cyclopentanone yield of 90.6%. ATR-IR results verify the catalytic mechanism and emphasize the importance of oxygen defects.
