Fabrication of NiO/SnO2 heterojunction based photocatalyst for efficient sunlight degradation of organic dyes

A new composite oxide (NiO/SnO2) photocatalyst was synthesized by simple co-precipitation route. The structural elucidation of composite oxide photocatalyst was carried out via X-rays diffraction (XRD) technique. The morphology was determined by scanning electron microscopy (SEM). The Fourier transf...
