Understanding the active copper sites of Cu/ZrO2 catalyst applied to direct conversion of ethanol to ethyl acetate and hydrogen
SATO, A. G.; VOLANTI, D. P.; NICÁCIO, J. V.; LONGO, E.; BUENO, J. M. C.
Artigo:
The origin and influence of active sites on supported copper catalysts, and their catalytic properties for ethanol conversion, were investigated using Cu/SiO2, Cu2O/SiO2, and Cu/ZrO2. Diffuse reflectance infrared Fourier transform spectroscopy of adsorbed CO revealed that Cu
