“…The increase in PCDD/Fs destruction is induced because of the NO addition. NO can be oxidized to NO 2 which has higher oxidation power than O 2 and is able to assist O 2 in the reoxidation step of V 4þ O x to V 5þ O x , thus accelerates the oxidation cycle of catalyst (Bertinchamps et al, 2005;Xu et al, 2012), as depicted in Fig. 4 (PCDDs as an example).…”
