Abstract

In this work we report self- Assemblies of nanoparticles of BI₂O₃ and layered double hydroxides (LDHS) obtained by exploiting the manifestation of the "structural memory effect" of znalldh and zncrldh anionic clay matrices in BI(NO₃)₃ aqueous solutions. controlled thermal treatment of BI₂O₃/znalldh and BI₂O₃/ZnCrLDH self- Assemblies gives rise to photoresponsive mixtures of mixed oxides, types BI₂O₃/ZnO-znal204 and BI₂O₃/ZnO- ZnCr₂O₄, respectively. powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS), high resolution transmission electron microscopy (tem) and UV-visible spectroscopy (UV-Vis) showed that the LDHs reconstruction in BI(no₃)₃ solutions gives rise to specific nanoarchitectonics characteristics in which small NPs of BI₂O₃ (∼ 5 nm) are highly dispersed on the larger NPs (∼150 nm) of znalldh and zncrldh. UV-Vis analysis indicates the cooperative absorbance capabilities of the novel catalytic systems that were evaluated in the degradation process of phenol from aqueous solutions under solar and UV light.
