| 英文摘要 | In this paper, we report experimentally and theoretically a surface photocatalysis reaction of 4-aminothiophenol (patp) to p,p'-dimercaptoazobenzene (dmab) on au, ag, and cu colloids. surface enhanced raman scattering (seas) spectra of patp on au and cu colloids are significantly different from the normal raman spectrum of patp powder. quantum chemical calculations reveal that patp on au and cu colloids is converted to dmab by a surface photocatalysis reaction, and all the strongly enhanced raman peaks are the symmetric ag vibrational mode by surface plasmon. the ph value effects on surface photocatalysis reaction were also investigated experimentally. it is found that plasmon-assisted surface photocatalysis reaction can be efficiently controlled by different ph values. the possibility of protonation of patp adsorbed on au and ag nanoparticles at ph 3 is investigated theoretically. the molecular mechanism is proposed for controlling surface photocatalysis reaction by ph values. |
