CHARACTERISTICS OF NANOCOMPOSITE MATERIAL ZrO2@GO:Bi3+ SYTHESIZED BY HYDROTHERMAL ULTRASONIC ASSISTED METHOD

Abstract

This paper presents the synthesis and characteristic properties of ZrO₂@GO nanocomposite doped with Bi³⁺ ions by simple hydrothermal method with the support of ultrasonic. The research aims to find new materials for treating difficult-to-decompose organic pollutants in wastewater. The characteristics of the vibrational functional groups are indicated by infrared spectrum, the crystal structure is characterized by X-ray diffraction. The surface morphology and optical properties of ZrO₂@GO nanocomposite material are characterized by FE-SEM, TEM and BET. The characteristics of vibrational modes and groups have been studied by Raman scattering spectrum. The results show that the ZrO₂@GO material consists of fairly uniform microspheres, with a diameter of about 20 - 30 nm, closely linked to graphene oxide sheets. The ZrO₂@GO:Bi³⁺ nanocomposites have a high surface area of ​​87.57 - 211.78 m²g^-1, a pore volume of 0.22 - 2.98 cm³g^-1 and a pore diameter of 4.74-8.95 nm. The ZrO₂@GO:Bi³⁺ nanocomposite materials have unique and outstanding properties, with great potential in treating wastewater contaminated with toxic organic substances such as dyes, antibiotics, pesticides and plant protection drugs.
