Outline of Final Research Achievements

This study aims at the development of a facile method for preparation of metallosilicate zeolites and their application to development of the novel synthetic pathway from bio-based hexoses into tetroses. A Hf-containing Beta zeolite that were prepared by a developed post-synthesis method with the addition of fluorine showed much higher catalytic activity than that prepared by without fluorine. The developed Hf-containing Beta zeolite successfully converted fructose into erythrose.
