摘要
•N-doped biochar/PDS system exhibited superior activity to selectively degrade BPA.•Electron transfer pathway played predominant role for BPA degradation.•The catalytic system had a strong anti-environmental interference ability.•The potential difference was the origin responsible for BPA selective degradation.•Graphitic N and pyridinic N were the essential active sites.
