Abstract
The present investigation reports a facile strategy for the synthesis of stable as well as visible-light active LaNdZr 2 O 7 /SnSe composite photocatalysts for applications in the degradation of Foron Blue azo dye. The as-synthesized photocatalysts have been characterized via several characterization techniques including x-ray diffraction (XRD) to confirm the phase of materials, scanning electron microscopy (SEM) coupled with energy-dispersive spectroscopy (EDS) to investigate the surface morphology as well as composition of synthesized materials, particle size distribution (PSD) and UV–vis diffuse reflectance spectroscopy (DRS) along with x-ray photoelectron spectroscopy (XPS) in order to draw the alignment of energy levels from the bandgap and valence band positions of photocatalysts, respectively. Foron Blue was degraded with a maximum efficiency up to 86.3% under visible-light illumination in 60 min by composite photocatalyst which is much higher as compared to SnSe and LaNdZr 2 O 7 photocatalysts. The higher photocatalytic activity over the composite might be attributed to efficient charge separation.
