Abstract

Article history: Received October 28, 2012 Received in Revised form December 6, 2012 Accepted 27 February 2013 Available online 1 March 2013 Silver indium sulfide (AgInS2) nanoparticles were synthesized by microwave method. These nanopartricles were characterized by FT-IR, XRD, DRS, SEM and TEM techniques. The band gap energy of 1.96 eV was determined by UV-Vis diffuse reflection spectrum (DRS). The photocatalytic activity was studied by photodegradation reaction of 2,4-dichlorophenol (2,4DCP) under visible light irradiation. The influence of initial concentration, initial solution pH on the degradation percentage of 2,4-DCP and also, the kinetics of photodegradation were investigated. The removal efficiency up to 95% proved the superior capability of AgInS2 (AIS) nanoparticles for water purification. © 2013 Growing Science Ltd. All rights reserved.

Highlights

  • The chlorophenols are extensively used as fungicide, herbicide, wood preservative, dyes and drugs[1,2]

  • There are no peaks in this spectrum, which represents the removal of organic sections via washing with ethanol and distilled water

  • The morphology of as-synthesized product was studied by Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) techniques

Summary

Introduction

The chlorophenols are extensively used as fungicide, herbicide, wood preservative, dyes and drugs[1,2] These materials have been listed as toxic pollutants by the various environmental protection agencies such as the United States Environmental Protection Agency[3]. AgInS2 is a ternary chalchogenide with direct band gap about 1.86-2.03 eV and high extinction coefficient in visible light region[14,15,16,17,18,19]. This compound can be introduced as a favorable material for photovoltaic and photocatalytic applications. The photocatalytic activity of AgInS2 nanoparticles was investigated for degradation of 2,4-dichlorophenol (2,4-DCP) under visible light irradiation
