CATALYST FOR PHOTODEGRADATION OF WATER AND PRODUCTION OF HYDROGEN BY USING THE SAME

摘要

PURPOSE:To obtain a catalyst acting stably in an aq. soln. and capable of efficient production of hydrogen under sunbeams and to produce hydrogen by using the catalyst. CONSTITUTION:A semiconductor excited by sunbeams is enclosed in a laminar compd. having cation or anion exchange ability to obtain the objective catalyst.
