  ABSTRACT: A room-temperature soakage procedure was carried out to successfully form and assemble CdS nanocrystallites into polyhedrons on the eggshell membrane (ESM). Based on the biomaterial ESM served as the reactive substrate and some ESM biomacromolecules acted as the surfactants, CdS nanocrystallites were in situ formed, further assembled into well-distributed polyhedrons, and finally performed CdS-ESM hybrid nanocomposites. This moderate bioinspired strategy would also be of great value to prepare novel functional nanocomposites.

  ABSTRACT: The reticular hierarchical structure of butterfly wings (Papilio Paris) is introduced as template for Au/TiO(2) photocatalyst by depositing the Au nanoparticles on TiO(2) matrix, which is carried out by a water-ethanol sol-gel procedure combined with subsequent calcination. The obtained Au/TiO(2) nanocomposites present the reticular hierarchical structure of butterfly wings, and Au nanoparticles with an average size of 7 nm are homogeneously dispersed in TiO(2) substrate. Benefiting from such unique reticular hierarchical structure and composition, the biomorphic Au/TiO(2) exhibits high-harvesting capability and presents superior photocatalytic activity. Especially, the biomorphic Au/TiO(2) at the nominal content of gold to titanium of 8 wt% shows the highest photocatalytic activity and can completely decompose methyl orange within 80 min, which is obviously higher than that of commercial Degussa P25 powders.
