Methanol and Acetic Acid from CH4 and CO2: The Role of Copper Speciation in Zeolite Cu-FER
Original language description
This study highlights the efficiency of Cu-FER catalysts with varying copper loadings in transforming carbon dioxide (CO2) and methane (CH4) into methanol or acetic acid. The XAS, UV-vis, and FTIR analyses confirmed that Cu-FER catalysts with low copper loading contain a high fraction of isolated Cu2+ cations, while those with high copper loading exhibit a significant presence of Cu oxo-species. In-situ studies (FTIR and mass spectrometry) revealed that bare Cu(II) cations, in synergy with Broensted acid sites, facilitate the conversion of CO2 and CH4 into acetic acid via coupled oxidation and carbonylation reactions. In contrast, the absence of Broensted acid sites and the dominance of Cu oxo-species in high-loaded Cu-FER favor the formation of methanol. Importantly, the findings confirm that the transformation of CO2 and CH4 into oxygen-containing products occurs under in-situ conditions, with products detected at temperatures below 300 degrees C. These results provide valuable insights for designing zeolite-based catalysts optimized for the selective production of specific oxygenated compounds from CO2 and CH4, offering a promising strategy for the utilization of these greenhouse gases.
