英文摘要	Selective hydrogenation of crotonaldehyde to crotyl alcohol over PDA (polydopamine) modified Co₃O₄ supported Pt catalysts was investigated in liquid phase. The catalysts which contain PDA and Co₃O₄ lead to the formation of two kinds of interfaces: Pt-PDA and Pt-Co₃O₄ , which greatly improves the performance in the hydrogenation of crotonaldehyde. TEM results reveal that the Pt nanoparticles of Pt/Co₃O₄ @PDA have a smaller size and better dispersion than Pt/Co₃O₄ . XPS, FT-IR and CO-DRIFTs results indicate that the addition of PDA decreases the electron density of Pt which is favor to the hydrogenation of C=O in crotonaldehyde. The characterization results demonstrate that the interaction between Pt and PDA creates new active interfacial sites and the synergy of Pt-PDA and Pt-Co₃O₄ is responsible for the excellent performance.
