A calibration error on our radiometer led us to misreport irradiance values for the UVC lamps used in our original manuscript.

The original statement:

“The precursor gas mixture (H2 and CO) was injected in the reactor with a molar ratio of 0.1/1 (H2/CO) and was irradiated by two UVC lamps (main emission peak at 253.7 nm, irradiance of 5.5 × 10−4 W/cm2 at 4.5 cm).”

The corrected statement:

“The precursor gas mixture (H2 and CO) was injected in the reactor with a molar ratio of 0.1/1 (H2/CO) and was irradiated by two UVC lamps (main emission peak at 253.7 nm, irradiance of 0.01 W/cm 2 at 3.5 cm).”
