Self-supported Ag nanoparticles on AgTi2(PO4)3 for hazardous dyes reduction in industrial wastewater
Abstract
<p>Silver based-nanoparticles (Ag NPs) have been recently shown to be promising catalysts for the degradation of toxic organic dyes in wastewater despite the challenges of recycling. In this paper, self-supported Ag NPs were obtained at the surface of AgTi<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> NASICON-type phosphates through in situ chemical reduction by sodium borohydride (NaBH<sub>4</sub>). The adopted approach enables the self-growth of zero-valent Ag NPs on the NASICON matrix, and concomitantly leads to the formation of Ag<sub>1−x</sub>Na<sub>x</sub>Ti<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub>. The crystalline structure, morphology and phase composition of the Ag nanocomposite has been characterized by several techniques. The catalytic performance of the as-fabricated Ag NPs/Ag<sub>1−x</sub>Na<sub>x</sub>Ti<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> has then been verified in the reduction of methylene blue (MB) and methyl orange (MO) dyes, chosen as target pollutants. Our findings reveal a good catalytic activity with an efficiency and time of reaction of respectively ∼ 96.30% and 320 s in the case of the MB reduction and ∼ 94.60% and 270 s in the case of the MO reduction. Additionally, the initial AgTi<sub>2</sub>(PO<sub>4</sub>)<sub>3</sub> phase can be regenerated via simple calcination route and recycled up to five times with no appreciable loss of catalytic activity.</p>
