a The hydrocarbon product distribution, CO2 conversion, and CO selectivity of activated CuFeO2 and activated Fe2O3. b The detailed hydrocarbon product distribution, the ASF plot, and the corresponding α value of activated CuFeO2. α is the probability of chain growth. R2 is the coefficient of determination, describing the goodness of linear fitting. Wn is the weight fraction of a product with n carbon atoms. CO2 conversion and product selectivity at c different space velocities and d different H2:CO2 ratios over activated CuFeO2. e Stability test of activated CuFeO2. For panels a and b, the reaction was conducted under 1 bar (H2:CO2 = 3:1) with a space velocity of 2400 mL h−1 gcat−1 at 320 °C after 4 h on stream. The reaction conditions for panels c–e are similar to that for panel a except for the space velocity, H2:CO2 ratio, and time on stream, respectively. The selectivity for hydrocarbon product excludes CO.
