A new insight on the core–shell structure of zerovalent iron nanoparticles and its application for Pb(II) sequestration

•The shell of nZVI is composed of 45.5% Fe(OH)3 and 54.5% FeOOH.•Fe(OH)3 shell suppresses the reduction of Pb(II).•Fe(OH)3 shell greatly promotes the co-precipitation and adsorption of Pb(II).•pH<4.5 favors Fe dissolution, while pH>4.5 promotes Pb(II) adsorption.•A reaction between Fe0 core, F...
