Photocatalytic properties of chemically grown vanadium oxide at 65°C

In this paper, the photocatalytic response of amorphous V2O5 coatings prepared by hydrothermal growth at 65°C is presented. The position of the substrate during the deposition and the pH of the solution were found to affect the coverage and the response of the coatings upon catalysis. The photocatal...

Description
Summary:In this paper, the photocatalytic response of amorphous V2O5 coatings prepared by hydrothermal growth at 65°C is presented. The position of the substrate during the deposition and the pH of the solution were found to affect the coverage and the response of the coatings upon catalysis. The photocatalytic activity of the coatings was tested using stearic acid as a pollutant for an illumination time of 480min. The materials grown on microscope glass positioned at an angle of 0° with respect to the bottom of the bottle exhibit the best photocatalytic activity, degrading stearic acid by 64% due to the enhanced surface coverage. •Hydrothermally grown amorphous V2O5 coatings at 65°C•Their properties are dependent on the substrate arrangement.•Their photocatalytic activity is correlated with the oxide coverage.
