摘要：

The adsorption of organics from the gas phase to solid and liquid surfaces is of great interest in the environment. In this study, the surface vibrational spectra of piperidine at the air/liquid interface, air/alumina (alpha-Al2O3, corundum) (0001) interface and air/alpha-alumina powder interface were obtained by using vibrational broad bandwidth sum frequency generation (SFG) spectroscopy. The interfacial vibrational signatures in the C-H stretching region of piperidine at the air/liquid and air/solid interfaces are shown to be sensitive spectroscopic-probes revealing the dominating interfacial species. Results indicated that the interfacial species at the air/water interface is mainly hydrogen-bonded piperidine, the interfacial species at the air/alumina (0001) interface is mainly protonated piperidine (piperidium) and the interfacial species at the air/alumina powder interface is mainly liquid-like piperidine.
