A P25/(NH₄)_xWO₃ hybrid photocatalyst with broad spectrum photocatalytic properties under UV, visible, and near-infrared irradiation.

ABSTRACT: In this study, a series of hybrid nanostructured photocatalysts P25/(NH₄)_xWO₃ nanocomposites with the average crystallite size of P25 and (NH₄)_xWO₃ of the sample was calculated to be about 30 nm and 130 nm, were successfully synthesized via a simple one-step hydrothermal method. The as-obtained samples was characterized by transmission electron microscopy (TEM), which implies that the P25/(NH₄)_xWO₃ nanocomposites are fabricated with favourable nanosizd interfacial. The XPS results confirmed that the obtained sample consists of mixed chemical valences of W⁵⁺ and W⁶⁺, the low-valance W⁵⁺ sites could be the origin of NIR absorption. As revealed by optical absorpt
