Novel plasma assisted preparation of ZnCuFeCr layered double hydroxides with improved photocatalytic performance of methyl orange degradation

Plasma assisted preparation of ZnCuFeCr layered double hydroxides used as photocatalyst showed excellent photocatalytic performance on methyl orange degradation under visible light. The catalysts were characterized by XRD, SEM, XPS, BET, UV–Vis DRS, EPR and PL. Compared with the traditional co-precipitation method, the plasma-assisted preparation of layered double hydroxides had obvious advantages of visible light photocatalysis. Plasma assisted...
