In a photocatalytic decomposition process of gas phase methanol using a photocatalytic reaction evaluation device for high vacuum, targeting a sample where Cu₂O fine particles are supported on TiO₂ nanotube array (TNA) which is a typical photocatalytic material showing ultraviolet light response an analysis of the various gas species generated was performed. Based on the results, we investigated and discussed about the influence of Cu₂O particulate support on the photocatalytic activity of TNA.
