Abstract
- Binary heterostructures Ag<subscript>2</subscript>ZrO<subscript>3</subscript>/TiO<subscript>2</subscript> composites have been prepared by a facile calcination-hydrothermal, using ZrOCl<subscript>2</subscript>·8H<subscript>2</subscript>O, AgNO<subscript>3,</subscript> and TBOT as raw materials and PVP as a dispersant. X-ray diffraction (XRD), transmission electron microscope (TEM), Raman spectrometer, XPS, UV-vis DRS, and photoluminescence (PL) were employed to characterize the Ag<subscript>2</subscript>ZrO<subscript>3</subscript>/TiO<subscript>2</subscript> composites. In an orthodox three-electrode system with RhB electrolyte solution, electrochemical measurements were carried out, and the results showed that it was a remarkable reversible reaction with reliable stabilization and favorable dynamics properties. The photocatalytic performances of Ag<subscript>2</subscript>ZrO<subscript>3</subscript>/TiO<subscript>2</subscript> composites were estimated via the dilapidation of RhB under visible-light irradiation. In comparison to the pure TiO<subscript>2,</subscript> the photocatalytic presentation of Ag<subscript>2</subscript>ZrO<subscript>3</subscript>/TiO<subscript>2</subscript> was enhanced. The presence of Ag<subscript>2</subscript>ZrO<subscript>3</subscript> formed well-matched band level and constructed a heterogeneous interface to remarkably modify the bandgap energy with prolonged charge separation. The binary Ag<subscript>2</subscript>ZrO<subscript>3</subscript>/TiO<subscript>2</subscript> composites can be regarded as a potential environmental material for applications in photocatalytic degradation of organic contaminants under visible-light irradiation.
