[Display omitted] •Decomposition and reformation pathways of PCDD/Fs are identified.•PCDD/Fs reformation is boosted as temperature rising but supressed at absence of O2.•Evolution of PCDD/F-signatures is studied for pathways revealing and verification.•Catalytic metal is more significant compared to...
