UiO-66-NH2负载Pd催化剂的合成、表征及其催化反应
Synthesis ,Characterization and Catalytic Reaction of UiO-66-NH2 Supported Pd Catalyst
摘要
Abstract
The heterogeneous bifunctional catalyst UiO-66-NH2/Pd with Pd nanoparticles has been prepared on metal-organic framework of UiO-66-NH2 using the impregnation and reduction method .The materials were characterized by X ray diffraction (XRD) ,Fu Liye transform infrared spectroscopy (FT-IR) ,transmission electron microscopy (TEM ) and scanning electron microscopy (SEM) .The resulting material of UiO-66-NH2/Pd was further evaluated as a potential bifunctional heterogeneous catalyst for olefine hydrogenations and Knoevenagel condensation between benzaldehyde and ethyl cyanoacetate .The results showed that the weight percent of Pd in UiO-66-NH2/Pd was 34.% and the average Pd particle size of was about 1 nm .The introduction of Pd nanoparticles did not change the framework integrity of UiO-66-NH2 .The resulting bifunctional catalyst of UiO-66-NH2/Pd was first tested in olefine hydrogenations and the results demonstrated that the material was active and stable as a heterogeneous catalyst .It could be reused for at least 6 times without significant loss of its catalytic performance in styrene hydrogenation .Remarkably ,its structure was stable during the reactions .Furthermore ,it also showed good activity and recycle stability in Knoevenagel condensation between benzaldehyde and ethyl cyanoacetate .关键词
