Abstract:In this paper, we combine the atomic layer deposition synthesis method of inverse opal with the hydrothermal growth of nanorods. From 460 nm polystyrene nanospheres opal crystals were produced using vertical deposition on Si wafers. The opal templates were covered with ZnO by atomic layer deposition. High temperature annealing was used to remove the polystyrene nanospheres to obtain the inverse opal structure. For the hydrothermal growth of ZnO nanorods, two production routes were analysed: hydrothermal reacti… Show more
“…The integration of electrical conduction is typically achieved by the addition of metal or semiconducting particles during the assembly, which, however, leads to problems with mechanical stability and in the preservation of the porous structure of the templating particles. 10,34 Other methods for preparing IOs using conductive materials exploiting atomic layer deposition (ALD) [35][36][37][38][39] or electrochemical deposition 40 are reported in the literature. In particular, ALD can coat the polymer colloidal crystal conformally and completely with the desired inorganic material.…”
Nanostructuration is a promising tool for enhancing the performance of sensors based on electrochemical transduction. Nanostructured materials allow increasing the surface area of the electrode, and to improve the limit...
