摘要Purification/separation of CO2 stream from carbon capture or other carbon source is highly energy consuming process. However, oxidative impurity of O-2 either deactivates catalysts in most carbon reduction systems, and thus reduces CO2 conversion efficiency. Here we report an effective method for splitting O-2-containing CO2 into CO, through a chemical looping scheme with Cu (5 at%) doped LaFeO3 perovskites as efficient oxygen carriers. Up to 2.28 mol/kg CO yield was achieved with high stability in the presence of O-2, five times higher than that with the state-of-the-art oxygen carrier, while pristine LaFeO3 perovskite only showed efficient capability of reducing pure CO2. Furthermore, the syngas productivity was doubled with Cu modification. Through experimental characterizations and ab initio calculations, we uncovered that the exsolution of metallic Cu on the surface of reduced perovskite was able to mitigate the competition between CO2 and O-2 in the re-oxidation step. We envision that the efficient CO2 splitter with well-designed oxygen carriers have the potential to facilitate economical combination of impure carbon feedstock and carbon utilization system.
