Nitrogen deficient porous nanosheets(NDCN) are a promising nano template that can combine defect engineering with Mn-FeOOH to suppress photo generated carrier complexation and optimize electron distribution. In this study, a unique structure with N/O double vacancies in Mn-FeOOH@NDCN was prepared using a magnesium thermal denitrification co-precipitation method. Furthermore, a series of Mn-FeOOH/NDCN/PMS reaction systems were constructed by adjusting the dosage of peroxymonosulfate(PMS). The experimental results indicate that the synergistic activation of N/O double vacancies on PMS enables th...
