Preparation of pod-shaped TiO₂ and Ag@TiO₂ nano burst tubes and their photocatalytic activity.

ABSTRACT: The pod-shaped TiO₂ nano burst tubes (TiO₂ NBTs) were prepared by the combination of electrospinning and impregnation calcination with oxalic acid (H₂C₂O₄), polystyrene (PS) and tetrabutyl titanate. The silver nanoparticles (AgNPs) were loaded onto the surface of TiO₂ NBTs by ultraviolet light reduction method to prepare pod-shaped Ag@TiO₂ NBTs. In this work, we analysed the effect of the amount of oxalic acid on the cracking degree of TiO₂ NBTs; the effect of the concentration of AgNO₃ solution on the particle size and loading of AgNPs on the surface of TiO₂ NBTs. Scanning electron microscopy and transmission electron microscopy investigated the surface morphology of samples. X-ra
