Preparation of a magnetically recyclable visible-light-driven photocatalyst based on phthalocyanine and its visible light catalytic degradation of methyl orange and p -nitrophenol

A magnetically recyclable metal organic composite (FeOCPc@Ni) was successfully prepared by a simple hydrothermal method and was characterised by FTIR spectroscopy, XRD, SEM, VSM and specific surface area and porosity analysis. More importantly, FeOCPc@Ni showed excellent photo-degradation performances for methyl orange (MO) under acidic conditions and of p -nitrophenol (PNP) under alkaline conditions. The degradation rates of MO and PNP were greater than 97.91% and 97.99%, respectively. In addition, after being reused 10 times, the degradation rates of MO and PNP respectively were 88% and 85%, showing good recyclability and reusability.
