Abstract

This Letter shows the activity of a novel metal/semiconductor photocatalyst for reducing CO₂ to CH₄ in the presence of H₂O under UV-light irradiation. This composite is prepared on a transparent conductive substrate by an hydrothermal method for depositing TiO₂ nanorod films, and then loaded with Cu nanoparticles (NPs) by an electrochemical method. The plasmonic properties of Cu NPs greatly enhance the resulting photoactivity with respect to that of pure TiO₂ nanorod films. The final CH₄ production rate observed (similar to 2.91 ppm/g_catal.h) represents an improvement compared to specific values reported by other authors using conventional titania-based catalysts.
