Functionalization-Mediated Preparation via Acid Precipitation and Photocatalytic Activity of In Situ Ag<sub>2</sub>WO<sub>4</sub>@WO<sub>3</sub>.H<sub>2</sub>O Nanoplates
Abstract
<jats:p>Tungsten oxide hydrate (WO<jats:sub>3</jats:sub>.H<jats:sub>2</jats:sub>O) nanoplates were in situ functionalized with AgNO<jats:sub>3</jats:sub> via a one-step acid precipitation method at room temperature. The functionalized product was the nanocomposite of Ag<jats:sub>2</jats:sub>WO<jats:sub>4</jats:sub> and WO<jats:sub>3</jats:sub>.H<jats:sub>2</jats:sub>O. Both pristine and functionalized samples had nanoplate morphology. The nanoplates’ dimension and uniformity decreased with the increase in the AgNO<jats:sub>3</jats:sub> amount, resulting in increased specific surface area. The AgNO<jats:sub>3</jats:sub> functionalization supported a growth via the orthorhombic WO<jats:sub>3</jats:sub>.H<jats:sub>2</jats:sub>O structure, caused a change in the dominant facet from (020) to (111), lessened the micro-strain, and enhanced the photocatalytic activity of samples under visible-light irradiation (<jats:italic>λ</jats:italic> ≥ 450 nm). The samples functionalized with 5 mass % of AgNO<jats:sub>3</jats:sub> showed the highest methylene blue degradation efficiency of 49% and a degradation rate of 0.122 mg g<jats:sup>−1</jats:sup> × min, which could be assigned to the largest specific surface area and the synergistic effect caused by the Ag<jats:sub>2</jats:sub>WO<jats:sub>4</jats:sub>@WO<jats:sub>3</jats:sub>.H<jats:sub>2</jats:sub>O junction. These results suggested a simple method for tailoring the dominant facet and morphology of WO<jats:sub>3</jats:sub>.H<jats:sub>2</jats:sub>O-based materials for visible-light-driven applications.</jats:p>
