Microwave-Assisted Hydrothermal Synthesis of Photocatalytic Truncated-Bipyramidal TiO₂/Ti₃CN Heterostructures Derived from Ti₃CN MXene.

ABSTRACT: TiO₂/MXene heterostructure has garnered significant interest as a photocatalyst due to its large surface area and efficient charge carrier separation at the interface. However, current synthesis methods produce TiO₂ without clear crystal faceting and often require complicated postprocessing step, limiting its practical applications. We demonstrate a facile and controlled microwave-assisted hydrothermal synthesis for transforming multilayered Ti₃CN MXene to a truncated-bipyramidal TiO₂/Ti₃CN heterostructure. The resulting TiO₂ nanocrystals at the Ti₃CN surface exhibited crystalline anatase truncated bipyramids, exposing {001} and {101} facets. We further tailored an indirect optical band gap of the TiO₂/
