Chemiluminescent reactions induced by gold nanoparticles

Article Abstract:

The reaction of gold nanoparticles with a KD04-NaOH-Na2CO3 solution gives rise to chemilumin essence with three emission bands at 380-390, 430-450, and 490-500nm. This could possibly be arising from emissive intermediates such as gold (I) complexes, carbon dioxide dimers and singlet oxygen molecular paus on the surface of the gold nanoparticles.

Activation of Au/TiO(sub 2) catalyst for CO oxidation

Article Abstract:

The adsorption and reaction of CO and CO2 on oxidation and reduced SrTio3(100) surfaces are presented. The result reveals the CO and CO2 molecules exhibit relatively weaker interactions with SrTiO3(100) compared to those with TiO2(110) and TiO2(100) surfaces.

In situ transient FTIR and XANES studies of the evolution of surface species in CO oxidation on Au/TiO2

Article Abstract:

The adsorption of CO and its reaction with oxygen is investigated using a combination of in situ Fourier transform infrared spectrometry. On this catalyst, the active CO species is adsorbed on metallic Au and exhibits an IR peak at 2090 cm(super -1).
