Among the tested monometallic catalysts using metal promoters, Zn/NZVI showed the highest reactivity with complete reduction of PNP in 5 min (k = 0.0263 s−1). The addition of Pd accelerated the degradation kinetics of PNP with complete reduction in 1 min (k = 0.095 s−1) but promoter's presence on bimetallic catalyst surfaces simply decreased their reactivity. A proper Pd amount (1.5 wt% Pd/NZVI) showed the highest degradation rate (k = 0.248 s−1), while after its content increased to 10 wt% the rate was reduced by 5.8 times.enAttribution-NonCommercial-ShareAlike 3.0 United StatesResearch Subject Categories::TECHNOLOGYType of access: Open AccessIron supported bimetallic catalystsNano-sized iron supportP-nitrophenol degradationPd promoterArticle
