In-situ DRIFTS spectra of DBC exposed to 10 ppm SO2 for 24 h under irradiation (a); comparison of sulfur-containing species formation under light and dark conditions (b); comparison of sulfur-containing species formation in the absence and presence of DBC under light irradiation (c); SO2 uptake on DBC (0.002 g)/SiO2(1 g) and SiO2(1 g) under different conditions (d); comparison of H2SO4 concentrations under different conditions (e); H2SO4 formation rate as a function of DBC concentration (f). Error bars represent standard deviation.
