A biomass carbon mass coated with modified TiO2 nanotubes/graphene for photocatalysis

Abstract

The powdered modified TiO2 materials are commonly used for photocatalysis. They are easily dispersed in solution but difficult to recycle. In addition, the low light transmission and lacking of oxygen in solution also cause the decrease of photocatalytic efficiency for practical application. Here we prepare a low-density circle slice which can be suspended on the surface of aqueous solution and enrich methylene blue easily. The body of the circle slice is a kind of biomass carbon derived from fungus while the surface of the circle slice is coated with Fe/N co-doped TiO2 nanotubes and N-doped graphene composite (Fe/N-TNTs/NG). The advantages are that the circle slice cannot only be convenient to recycle, but also be easy to receive light and oxygen. According to the photocatalytic activity test, the floatable material consisting of Fe/N-TNTs/NG and fungus shows superb performance on the degradation of methylene blue under simulated solar irradiation, which makes it a promising photocatalysis material.
