• -S2 sample has the highest •OH and •O2− signal intensity. This indicates that the sample has the highest number of •OH and •O2− radicals. Therefore, it shows the best pollutant degradation performance. •OH and •O2− radicals can degrade organic pollutants (MB) into nontoxic CO2 and water. Furthermore
