3-D ordered macroporous (3DOM) crystalline CsxH3-xPW12O40 and (NH4)(x)H3-xPW12O40 were synthesized by a colloidal crystal template method. CsxH3-xPW12O40 and (NH4)(x)H(3-x)PW(12)O(40)were deposited in the voids of templates by a two-step impregnation process and homogeneous precipitation, respectively, and polymer templates were removed by subsequent calcination. 3DOM crystalline CsxH3-xPW12O40 exhibits trimodal micro-, meso-, and macroporosity.
