TEMPLATE STRATEGY FOR THE SYNTHESIS OF Cu₂O–Pt HIERARCHICAL HETEROSTRUCTURES FOR THE DEGRADATION OF METHYLENE BLUE

Abstract

A facile and green route was introduced to synthesize Pt nanoparticles (PtNPs) immobilized on Cu 2 O octahedrons to form Cu 2 OÀPt hierarchical heterostructure. Transmission electron microscopy (TEM),¯eld emission scanning electron microscopy (FE-SEM), high resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS) and X-ray di®raction (XRD) were employed to study their morphology, chemical and crystallographic properties of the Cu 2 OÀPt hierarchical heterostructure. These novel Cu 2 OÀPt hierarchical heterostructures show fascinating degradations of methylene blue (MB), due to the suppressed electron/hole recombination phenomena and the e±cient ability to capture the light.
