Hydrothermal synthesis of a photocatalyst based on Byrsonima crassifolia and TiO for degradation of crystal violet by UV and visible radiation.

This work presents a one-step synthesis methodology for preparing a hydrochar (HC) doped with TiO (HC-TiO) for its application on the degradation of crystal violet (CV) using UV and visible radiation. Byrsonima crassifolia stones were used as precursors along with TiO particles. The HC-TiO sample was synthesized at 210 °C for 9 h using autogenous pressure.
