Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
We report on free-standing Ta3N5 nanotubular membranes with open top and bottom, used as visible-light-active, flow-through photocatalytic micro-reactors. We grow first a robust anodic Ta2O5 layer, lift-off a membrane and convert to Ta3N5. Such membranes can easily, in a flow-through mode, degrade methylene blue under visible light (wavelength 4400 nm) or solar illumination.
