Abstract

Visible-light-driven semiconducting photocatalysts of Ag₃PO ₄ were prepared by a hydrothermal method, and were optimized by adjusting reaction conditions, i.e., temperature, pH of reaction solution, concentration of feedstock, and time of hydrothermal process. The obtained photocatalysts were then systematically characterized by different instruments, such as XRD, UV-vis, FESEM, and BET, to reveal the physicochemical properties. Furthermore, activities of photocatalysts for visible-light-driven O₂ evolution were evaluated, demonstrating that the photocatalytic activity of Ag₃PO₄ prepared by hydrothermal reaction (initial rate of O₂ evolution, 1156 μmol g^-1 h^-1) was more than two times as that of sample prepared by room-temperature reaction (initial rate of O₂ evolution, 533 μmol g^-1 h^-1), which could be attributed to its better ability to utilize visible light and more regulated morphology.
