Gold-nanoparticle-modified TiO2 nanowires for plasmon-enhanced photocatalytic CO2 reduction with H2 under visible light irradiation

Abstract: Gold-nanoparticles (Au-NPs) incorporated TiO2-nanowires (TiO2-NWs) of controlled sizes prepared via hydrothermal and chemical reduction method have been investigated for CO2 photoreduction with H2 under visible light irradiations. The nanocatalysts have been characterized by XRD, FESEM, TEM, N2 adsorption–desorption, XPS, UV–vis and PL … Continue reading
