Two kinds of seeds are studied as non-metallic bio-precursors to synthesize biogenic N-P-codoped SnO(2) (BNP-SnO(2)). The as-prepared BNP SnO(2) samples are characterized by X-ray diffraction (XRD) , scanning electron microscopy (SEM) an UV absorption spectroscopy. Photocatalytic activity of BNP- SnO(2) are studied with experiments of Triton X-100 degradation under a 400 W high pressure mercury lamp irradiation. The results show higher photocatalytic activity of BNP- SnO(2) than SnO(2) nanometer. This work may pave a new and easy way to use of biomass to synthesize of doped metal oxides.
