Researchers from Xiamen University Report Details of New Studies and Findings in the Area of Chalcogens

May 6, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Chalcogens is the subject of a report. According to news reporting from Xiamen, People's Republic of China, by NewsRx journalists, research stated, "Surface plasmon resonances (SPRs) have been found to promote chemical reactions. In most oxidative chemical reactions oxygen molecules participate and understanding of the activation mechanism of oxygen molecules is highly important."

The news correspondents obtained a quote from the research from Xiamen University, "For this purpose, we applied surface-enhanced Raman spectroscopy (SERS) to find out the mechanism of SPR-assisted activation of oxygen, by using p-aminothiophenol (PATP), which undergoes a SPR-assisted selective oxidation, as a probe molecule. In this way, SPR has the dual function of activating the chemical reaction and enhancing the Raman signal of surface species. Both experiments and DFT calculations reveal that oxygen molecules were activated by accepting an electron from a metal nanoparticle under the excitation of SPR to form a strongly adsorbed oxygen molecule anion. The anion was then transformed to Au or Ag oxides or hydroxides on the surface to oxidize the surface species, which was also supported by the heating effect of the SPR."

According to the news reporters, the research concluded: "This work points to a promising new era of SPR-assisted catalytic reactions."
