Template synthesis of alumina gel with a nanohoneycomb structure

Abstract

The effect of isooctylphenol poly(ethylene glycol) ether (C 8H17C6H4O[C2H 4O]10H) on the structure of aluminum oxyhydrate is studied. It is established that, after being dried, gels that form from the mixture of aluminum nitrate, surfactant, and ammonia (concentrations in the final mixture of 9, 9, and 6 wt %, respectively) solutions have a lamellar structure with a layer thickness of 60-80 nm. Each layer of the lamellar phase consists of hexagonal prisms with an edge length of 100-120 nm, which are assembled into a honeycomb or a graphite-like structure. © 2009 Pleiades Publishing, Ltd.
