摘要：

A possible FeSbO4 phase was detected at a poreless silica surface using Mossbauer spectroscopy and infrared absorption of pyridine adsorbed on the surface. The phase was obtained from Fe(CO)(5) as starting material, without calcination treatment. Attempts to synthesizing the FeSbO4 phase using a porous silica gel, under these conditions failed. The influence of the pores on the support is discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.
