abstract	Porous V<sub<2</sub<O<sub<5</sub</TiO<sub<2</sub< nanoheterostructure films with different atomic ratios of Ti/V (4:1, 2:1, 1:1, and 1:2) were synthesized by a sparking method for the first time. The sparking method, which is a simple and cost-effective process, can synthesize highly porous and composite films in one step. Field-emission scanning electron microscope (FE-SEM) images revealed the porosity morphology of all prepared samples. V<sub<2</sub<O<sub<5</sub</TiO<sub<2</sub< nanoheterostructure films were confirmed by Raman spectroscopy, high-resolution transmission electron microscopy (HRTEM), and X-ray photoelectron spectroscopy (XPS). The secondary particle size and band gap of the samples were highly correlated to the V<sub<2</sub<O<sub<5</sub< proportion, resulting in enhanced visible-light absorbance. V<sub<2</sub<O<sub<5</sub</TiO<sub<2</sub< nanoheterostructure films at an atomic ratio of 1:1 showed the highest photocatalytic performance, which improved the degradation rate up to 24% compared to pure TiO<sub<2</sub< film. It is believed that the formed nanoheterostructure and greater portion of V<sup<4+</sup< ions are reflected by this ratio.
abstractGer	Porous V<sub<2</sub<O<sub<5</sub</TiO<sub<2</sub< nanoheterostructure films with different atomic ratios of Ti/V (4:1, 2:1, 1:1, and 1:2) were synthesized by a sparking method for the first time. The sparking method, which is a simple and cost-effective process, can synthesize highly porous and composite films in one step. Field-emission scanning electron microscope (FE-SEM) images revealed the porosity morphology of all prepared samples.
