Abstract Interaction of small (≈ 5 nm) CeO2 particles with silica catalyst carrier in hydrogen at 570–970 K was studied by XRD and TEM. It was found that, at 770 K, CeO2 began to redisperse and spread onto silica and at 970 K its complete amorphization occurred. Addition of 0.4 wt% Pd had a small promoting effect on the process.
