X-Ray diffraction, Raman and diffusion-reflectance absorption IR-spectroscopy are used to compare physical-chemical surface properties of In-Zr mixed nanocrystalline oxides, synthesized in supercritical water (SCW) and via conventional co-preci pitation technique. Samples synthesized in SCW have more stable surface properties. The basicity of mixed In-Zr oxides increases along with increasing In content.
