“…In order to synthesize porous CeO2 photocatalyst materials, a hard template method was employed by using commercial silica microspheres as a template [8]. Highly structured macroporous materials composed of uniform pore networks of micrometer level have recently been synthesized by the template method and applied into to many researches, such as photonic, optical, and catalytic applications, due to the main features of high surface area and uniform macropore arrangement.…”

Removal of lead ions from water was conducted by a coupling approach of adsorption and photoelectrodeposition over a macroporous CeO2 photocatalyst loaded with ZnO. The photocatalyst was prepared by the hard template method and the impregnation method. The various size of silica spheres (0.05-0.4 µm) were used as a template for the photocatalyst, and the highest BET surface area (73.8 m 2 /g) was given in the sample prepared with the smallest silica sphere (0.05 µm). In the removal of lead ions, the porous sample showed a large amount of removal of lead ions. In addition, the ZnO loaded catalysts showed a larger amount of removal for lead ions than an unloaded catalyst under the UV light irradiation. In the reaction, since zinc ions were simultaneously dissolved to the solution, it was suggested that this reaction was the ion-exchange reaction between lead ions and zinc ions and was promoted by the UV light irradiation.
