摘要: Abstract Zinc tetracarboxyphenoxy phthalocyanine was covalently linked to Gd 2 O 3 nanoparticles for the photocatalytic degradation of Orange G. Characterization composite carried out using XRD, TEM, XPS, UV–vis spectroscopy and FT-IR spectroscopy. The showed improved photophysical properties over alone catalyst found be reusable. Analyses photodegradation rates azo dye indicated pseudo first-order kinetics.
