In this study, ferrate intercalated Ca/Al-layered double hydroxide (Ferrate-LDH) was synthesized and characterized for water treatment. In the new Ferrate(VI) material, ferrate was stably present in the LDH interlayers, in agreement with results of the Density Functional Theory simulation. The oxidative capability of Ferrate-LDH was examined in terms of the mineralization of phenol in water. The Ferrate-LDH could achieve up to 86.8% utilization efficiency during oxidative destruction of phenol in water (pH = 6.5, TOC = 38.3 mg/L), advantageous over direct ferrate addition that only achieved 12.6% utilization efficiency. A slower evolution of dioxygen (a final product of Ferrate(VI) self-decay) …
