The release of crude oil and water-soluble dyes into our marine environment is a major
global problem. An efficient semiconductor Ag–Ag<sub>3</sub>PO<sub>4</sub> photocatalyst
was synthesized using formaldehyde as a reducing agent to form surface active Ag on
Ag<sub>3</sub>PO<sub>4</sub> under microwave radiation for heating, and its potential
in destroying environmental pollutants has been examined. The diffuse reflectance
spectroscopy of Ag–Ag<sub>3</sub>PO<sub>4</sub> revealed an enhanced absorption in
the visible light region. The rate of photocatalytic degradation of rhodamine B by
Ag–Ag<sub>3</sub>PO<sub>4</sub> was over 4-fold compared to Ag<sub>3</sub>PO<sub>4</sub>.
The potential application of Ag–Ag<sub>3</sub>PO<sub>4</sub> in oil spill remediation
was also examined through photocatalytic degradation of benzene, <i>n</i>-hexane,
and 1:1 v/v benzene/methanol crude oil-soluble fractions. UV–vis and gas chromatography–mass
spectrometry analysis of the crude oil components after visible light irradiation
showed excellent degradation. The photocatalytic efficiency enhancement of Ag–Ag<sub>3</sub>PO<sub>4</sub>
is attributed to the excellent electron trapping of silver nanoparticles deposited
on the surface of Ag<sub>3</sub>PO<sub>4</sub>. This work will motivate future studies
to develop recyclable visible light photocatalysts for many applications. |
