A highly hierarchically ordered macroporous–mesoporous Ce0.4Zr0.6O2 solid solution with crystalline framework walls was directly and simply prepared using polystyrene (PS) microspheres and a block copolymer as dual templates. The PS microspheres and block copolymer were assembled into colloidal crystals and mesoscopic rod-like micelles as macroporous and mesoporous templates, respectively, by a one-step process. This process offers a facile method to prepare hierarchically ordered porous materials. Compared to commercial ceria, the macroporous–mesoporous Ce0.4Zr0.6O2 material significantly improved the ultraviolet resistance and mechanical performance of a polysulfide polymer. Because the ordered macroporous–mesoporous Ce0.4Zr0.6O2 can disperse uniformly in the polysulfide polymer based on the open macroporous structure for diffusion and mobility and mesoporous structure for high surface areas. Furthermore, these results show that better-performing polysulfide polymers can be achieved by adding hierarchically structured materials.

Abstract
A highly hierarchically ordered macroporous–mesoporous Ce0.4Zr0.6O2 solid solution with crystalline framework walls was directly and simply prepared using polystyrene (PS) microspheres and a block copolymer as dual templates. The PS microspheres and block copolymer were assembled into colloidal crystals and mesoscopic rod-like micelles as macroporous and mesoporous templates, respectively, by a one-step process. This process offers a facile method to prepare hierarchically ordered porous materials. Compared to commercial ceria, the macroporous–mesoporous Ce0.4Zr0.6O2 material significantly improved the ultraviolet resistance and mechanical performance of a polysulfide polymer. Because the ordered macroporous–mesoporous Ce0.4Zr0.6O2 can disperse uniformly in the polysulfide polymer based on the open macroporous structure for diffusion and mobility and mesoporous structure for high surface areas. Furthermore, these results show that better-performing polysulfide polymers can be achieved by adding hierarchically structured materials.
