Self-grown Ag2O nanoparticles on Ag-NASICON material for efficient visible light photocatalysis
Abstract
<p>Ag-containing semiconductors have gained great attention due to their outstanding visible light-responsive photocatalytic properties. In the current work, silver oxide (Ag<sub>2</sub>O) nanoparticles were in situ self-grown on the surface of AgZr<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> NASICON-type material using sodium hydroxide-assisted precipitation to form an Ag<sub>2</sub>O/Ag<sub>1-x</sub>Na<sub>x</sub>Zr<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> nanocomposite. The crystalline structures, morphological observations, elemental composition, and optical properties of the prepared product were carried out using various characterization methods. The photocatalytic performance of Ag<sub>2</sub>O/Ag<sub>1-x</sub>Na<sub>x</sub>Zr<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> has then been explored in the decomposition of methyl orange (MO) wastewater pollutant under visible light. The obtained photocatalyst exhibited excellent decomposition efficiency (95.08 %, k = 0.0303 min<sup>−1</sup>) for MO removal within 60 min. In addition, the prepared nanocomposite exhibited proper reusability even after five successive cycles without any significant loss in photocatalytic activities. Furthermore, a simple catalyst regeneration strategy based on hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) was adopted, revealing that the spent photocatalyst can achieve nearly total self-regeneration to the initial AgZr<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> material.</p>
