Electronic Structure Studies and Photocatalytic Properties of Cubic Bi1.5ZnNb1.5O7

BZN structures viewed along the direction, assuming (a) random, (b) ordered, and (c) partially ordered solid solutions. Bi, Nb, Zn, and O atoms are yellow, blue, red, and green balls, respectively. Rules for color mixing are used to represent sites with fractional occupancy; therefore, Bi/Zn and Nb/Zn sites become orange (yellow + red) and purple (blue + red), respectively.
