Abstract

CeO₂ nanocrystals of cubic and rod shape have been synthesized under hydrothermal conditions on controlling the pH, temperature and duration of reaction. High-resolution transmission electron microscopy indicates that exposed crystal planes are {1 1 0} and {1 0 0} for rods but {1 0 0} for cubes. These nanocrystals have been used in the preparation of a Rh/CeO₂ catalyst on an Al₂O₃ support to test the catalytic activity for ethanol reforming. These catalysts as prepared show good H₂ selectivity compared to catalysts with irregular CeO₂ nanoparticles. The {1 0 0}/{1 1 0}-dominant surface structures play a crucial role in enhancing ethanol reforming; this reaction is important for fuel-cell applications.
