摘要：

A new one-step solid-state reaction synthesis of tin oxide (SnO2) nanoparticles has been developed. The process is a convenient, inexpensive and efficient preparation for SnO2 nanomaterial with adjustable grain sizes in the range of 3-15 nm in high yield. They can be dispersed into EtOH or distilled water. The prepared SnO2 nanoparticles have high sensitivities towards reducing gases. (C) 2002 Elsevier Science B.V All rights reserved.
