Adsorption-photoreduction behaviors and mechanisms of layered double hydroxide loaded on uranium(vi) removal

The low-cost NiAl exhibits high efficiency for U( vi ) decontamination, involving surface complexation and photocatalytic reduction. The photogenerated electrons and generated ˙O 2 − radicals reduced the absorbed U( vi ) into insoluble UO 2 (s) and U 3 O 8 .
