Abstract
Ti-BEA and Ti-FAU, obtained by post-synthesis treatment, and TS-1, obtained by direct hydrothermal synthesis, have been tested as catalysts for the Ru ff oxidative degradation of calcium d-gluconate to d-arabinose using dilute d hydrogen peroxide as oxidant. Only large-pore zeolites Ti-BEA and Ti-FAU were found to be active. It was shown, in particular, that a very rapid lea ching of titanium occurred and that the titanium species present in the sol ution were responsible for the catalytic activity observed.
