Catalytic wet air oxidation of bisphenol A model solution in a trickle-bed reactor over titanate nanotube-based catalysts

► Hydrothermal synthesis route produced high surface area titanate nanotubes. ► Complete removal of bisphenol A was achieved in the CWAO process. ► Significant TOC conversions were attained over bare TiO2-based catalysts. ► Negligible amount of carbonaceous deposits was accumulated on the catalyst surface.
