Abstract
|
The continuous development of industrial activities and also changing climate of worldwide lead to increase water pollutants and the eradication of safe water sources. Hence, remediation of wastewater and reduction of water pollutants notably organic dyes have become a serious environmental challenge. Reducing organic pollutants by heterogeneous nanocatalysts can be employed as an efficacious manner to overcome this problem. Accordingly, a nanocomposite catalyst consisting of zirconium oxide or zirconia nanoparticles (ZrO2 NPs) and gold (Au) NPs were made by means of a straightforward and green route. Au NPs were firstly prepared via laser ablation in liquid (LAL) method and then deposited on the ZrO2 NPs with the size of 53–88 nm using the magnetic stirring approach. The characterization methods indicated that the ZrO2-Au nanocomposite was successfully fabricated. The catalytic performance of ZrO2-Au catalyst for the degradation of methylene orange (MO) and methylene blue (MB) was investigated.
