摘要: Abstract The reaction between CO2 and C2H4 in the presence of H2 over Pt PtSn-based (SiO2, Al2O3, MgO) supported catalysts has been studied at 34 bar total pressure 423 K by situ diffuse reflectance infrared Fourier transform spectroscopy on-line mass spectrometry experiments. Over silica-supported PtSn alloy, yields 2-hydroxypropanoic acid through a C2-carbonylic species nondissociatively coordinated. chemisorption on PtSn/SiO2 produces which interacts with hydroxyl groups SiO2, this evolves to acetaldehyde K. 2-Hydroxypropanoic is also produced from acetaldehyde, CO2, H2, but not ethanol CO2.
