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.
