Degradation of Organic Dyes by the UCNP/h-BN/TiO₂ Ternary Photocatalyst.

ABSTRACT: In this study, upconversion nanoparticles (UCNPs) with a flower-like morphology were prepared using a urea coprecipitation method. A ternary photocatalyst was first prepared using a solvothermal method involving the use of titanium oxide (TiO₂), hexagonal boron nitride (h-BN), and UCNPs (Y₂O₃, Yb³⁺, and Tm³⁺) as raw materials. The surface morphology, crystal structure, and functional groups of these materials were then characterized and analyzed through scanning electron microscopy, transmission electron microscopy, X-ray diffraction analysis, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, ultraviolet-visible spectrophotometry, and other techniques. Photocatalytic experiments were also conducted to investiga
