Abstract

K3Ta3B2O12 is photocatalyst that exhibit relatively high water splitting activity without co-catalyst, was synthesized by various solution methods. Obtained samples were characterized by X-ray diffraction. Samples synthesized by complex gelation method and polyamide-type polymerizable complex method ware single phase K 3Ta3B2O12 Sample synthesized by complex gelation method was tested for water splitting activity, and this sample has little water splitting activity without co-catalyst. When NiO 0.5 wt% as co-catalyst was loaded to samples, hydrogen generated 1600 μmol/h.
