Mesoporous Boron-Doped TiO2/Mussel Shell for Photocatalytic Degradation of Dye X-3B

In this study, a novel hybrid boron-doped titanium oxide–coated waste mussel shell (B-TiO 2 /shell) composite with good visible absorption was synthesized via hydrothermal method. The B-TiO 2 /shell exhibited a higher photocatalytic oxidation efficiency of X-3B than that of naked B-TiO 2 under visib...

Description
Summary:In this study, a novel hybrid boron-doped titanium oxide–coated waste mussel shell (B-TiO 2 /shell) composite with good visible absorption was synthesized via hydrothermal method. The B-TiO 2 /shell exhibited a higher photocatalytic oxidation efficiency of X-3B than that of naked B-TiO 2 under visible irradiation, due to the synergic effect from the well-dispersed B-dopant mixed phase crystalline structures (anatase and brookite crystals) and the adsorption from shell matrix. The photodegradation kinetics of X-3B can be described by the pseudo-first-order rate expression with chemisorption-controlled process, and regeneration experiments indicated its reusability. The present B-TiO 2 /shell would be applicable as economical and efficient photocatalyst for wastewater treatment.
