a Photothermal catalytic performance of Cu/ZnO/Al2O3(CZA), S1, and S2 in the batch reactor. Reaction conditions: H2/CO2 ratio = 3:1, 30 Psia, and ~20 suns light intensity with a duration of 0.5 h without external heat. b Methanol selectivity with different H2: CO2 ratios; D indicates dark, L indicates light, and B indicates batch reactor. c CO rate of S2 in a flow reactor under light/dark conditions, and d the corresponding Arrhenius plot. e Methanol rate of S2, and f the corresponding Arrhenius plot. Conditions for flow measurement: atmospheric pressure, H2/CO2 ratio = 1:1 with a total flow rate of 4 mL min−1, and light intensity of 6 suns.
