2D hexagonal yttrium doped SnO2 nanoplatelets for photocatalytic degradation

Abstract

In this work, two-dimensional hexagonal nanoplatelets were analyzed through a simple morphological and structural evolutions. XRD analysis of SnO 2 and Y doped SnO 2 has revealed a tetragonal structure and photoluminescence spectra exhibited a visible emission broadband peak around 464 nm and 528 nm. SnO 2 : Y (7 wt.%) photoluminescence spectra con rm the higher charge separation and which impede the electron-hole recombination. It has been shown that hexagonal SnO 2 :Y (7 wt.%) nanoplatelets perform better in photocatalytic degradation than conventional spherical nanoparticles. EIS measurements were performed to investigate the charge carrier movement of both undoped and Y doped SnO 2 NPs. Our study is the rst to illustrate the two-dimensional morphology of SnO 2 :Y (7 wt.%) hexagonal nanoplatelets and their application integration of photocatalytic materials.
