| Research Abstract |
We have developed a method of recovering gold from solution using organic-inorganic hybrid photocatalysts based on surfactant and polyoxometallate. Gold ions are photo-reduced by the hybrid photocatalyst under UV light irradiation at the interface between water and an organic solution in which the photocatalyst is dissolved. Among the catalyst tested, the catalyst based on γ-SiW_<10>O_<36>^<8-> showed high activity for recovery of gold. It was found that the gold particles formed were sheet-like, indicative of their catalytic formation at the water/organic solution interface.
