Characterization of Catalytic Performance under Solar Light Irradiation
(A) Photograph of up-scaled reaction with volume of 2.7 L.
(B) Amplification reaction with 100 g styrene and the temperature and light intensity change curve. Catalytic setup was placed on a rooftop (latitude 37°51′ north, longitude 112°32′ east) so that the reactor would be directly irradiated by the sun for the duration of the experiment. Reaction conditions: 100 g of styrene, 2,500 mL of acetonitrile, 200 mL of isobutyraldehyde, 10 g of catalyst, bubble with 1.5 L of oxygen every day, May 28 to June 11, 2020, 25 °C–35 °C, light intensity 13–85 mW/cm2. Conv., conversion; Sel., selectivity.
