Abstract

original image

Visibly clear: A family of visible-light-responsive MCr–layered double hydroxides (LDHs; M=Cu, Ni, Zn) were synthesized. These show remarkable photocatalytic activity with visible-light irradiation. Experimental and computational studies revealed that the visible-light response of MCr[BOND]NO3–LDHs originates from a d–d transition in the orderly dispersed CrO6 octahedra in the hydrotalcite layer.
