Efficient Visible-Light-Driven Photocatalytic Degradation with Bi<sub>2</sub>O<sub>3</sub> Coupling Silica Doped TiO<sub>2</sub>
A new
TiO<sub>2</sub>-based visible light photocatalyst (Bi<sub>2</sub>O<sub>3</sub>/Si–TiO<sub>2</sub>) was synthesized by
both Bi<sub>2</sub>O<sub>3</sub> coupling and Si doping via a two-step
method. The structural, morphological, light absorption, and photocatalytic
properties of as-prepared samples were studied using various spectroscopic
and analytical techniques. The results showed that Bi<sub>2</sub>O<sub>3</sub>/Si–TiO<sub>2</sub> catalysts held an anatase phase
and possessed high thermal stability. The doped Si was woven into
the lattice of TiO<sub>2</sub>, and its content had a significant
effect on the surface area and the crystal size of Bi<sub>2</sub>O<sub>3</sub>/Si–TiO<sub>2</sub>. The introduced Bi species mainly
existed as oxides on the surface of TiO<sub>2</sub> particles, and
the Bi<sub>2</sub>O<sub>3</sub> photosensitization extended the light
absorption into the visible region. Bi<sub>2</sub>O<sub>3</sub> coupling
also favored the separation and transfer of photoinduced charge carriers
to inhibit their recombination and Si doping enlarged the surface
area of photocatalysts. Compared to bare TiO<sub>2</sub>, Bi<sub>2</sub>O<sub>3</sub>/TiO<sub>2</sub>, and Si–TiO<sub>2</sub>, Bi<sub>2</sub>O<sub>3</sub>/Si–TiO<sub>2</sub> samples showed better
activities for the degradation of methyl orange (MO) and bisphenol
A (BPA) under visible light irradiation (λ > 420 nm). The
highest
activity was observed for 1.0% Bi<sub>2</sub>O<sub>3</sub>/15% Si–TiO<sub>2</sub> calcined at 500 °C. The superior performance was ascribed
to the high surface area, the ability to absorb visible light, and
the efficient charge separation associated with the synergetic effects
of appropriate amounts of Si and Bi in the prepared samples. The adsorbed
hydroxyl radicals (<sup>•</sup>OH) were also found to be the
most reactive species in the photocatalytic degradation
