Hollow In2O3 nanotubes decorated with Cd0.67Mo0.33Se QDs for enhanced photocatalytic hydrogen production performance

Novel Cd 0.67 Mo 0.33 Se/In 2 O 3 hollow nanotubes were prepared for photocatalytic hydrogen production application. Under visible light irradiation , Cd 0.67 Mo 0.33 Se/In 2 O 3 hollow nanotubes showed enhanced photocatalytic performance. And the apparent quantum efficiency of 34.86% was obtained when irradiated with 420 nm monochromatic light. The modification of Cd 0.67 Mo 0.33 Se QDs on the surface of In 2 O 3 hollow nanotubes effectively improved the utilization rate of light absorption, increased the separation and migration rate of electrons, inhibited the recombination of photo-generated electron and hole pairs, thus enhancing the photocatalytic activity of water splitting to produce hydrogen . It would be an efficient photocatalyst for hydrogen production application in future.
