Biomass-derived porous ZrTiO4 nanotubes with controlled wall-thickness for enhanced photocatalytic activity

We present a novel and facile fabrication of wall-thickness controlled ZrTiO 4 nanotubes (ZTNTs) using bacterial cellulose (BC) as a template. Unique porous thin-walls and interconnected channels within ZTNTs contribute a lot to the enhanced photodegradation activity. The roles of the wall-thicknesses in physicochemical properties as well as photocatalytic activities were careful investigated which might extend the synthesis of other nanotubes with higher catalytic performance.
