Sulfate formation is dominated by manganese-catalyzed oxidation of SO2 on aerosol surfaces during haze events

Abstract The formation mechanism of aerosol sulfate during wintertime haze events in China is still largely unknown. As companions, SO 2 and transition metals are mainly emitted from coal combustion. Here, we argue that the transition metal-catalyzed oxidation of SO 2 on aerosol surfaces could be th... View More
