Abstract

En 中文

• Cu (I) and CO active sites formed on Cu/BC and took part in the activation. • R-O• and 1O2 were the main contributors to SMX degradation in Cu/BC-PAA. • Degradation by-products and pathways of SMX in Cu/BC-PAA system was detected. • Cu/BC-PAA performed an environmental safety and reusability in recycles.
