Abstract

Abstract : In this study, new porous gold nanospheres were prepared by calcination of the auriferous urea complex. The results showed that the active site of ethanol at porous Au nanospheres was –CH2, which enhanced the activity of C–H in –CH2 . Abstract : Novel porous gold nanospheres are prepared by calcination of the gold–urea complexes. The enhanced Raman spectra of ethanol catalyzed by different doses of porous gold nanospheres are measured with a 532 nm laser as the excitation source, and an enhanced charge coupled device served in spectral detection and microscopic imaging. The electrochemical experiments show that the catalytic oxidation products of ethanol with porous gold nanoparticles are acetaldehyde, acetic acid, and water, which further proved that the porous gold nanoparticles can activate the –CH2 of ethanol.
