Synthesis and Characterization of Novel Composite-Based Phthalocyanine Used as Efficient Photocatalyst for the Degradation of Methyl Orange

Abstract

In this study, Copper-tetraaminophthalocyanine (CuTAP) was supported on polyvinylcholoride by reflux condition to produce heterogeneous recovarable catalyst. This catalyst was characterized using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Scanning electron microscopy (SEM) and UV-vis spectroscopy. The results showed that the photocatalytic degradation of methyl orange was performed in mild conditions at ambient pressure and temperature under visible light. The synthesized catalyst could be readily separated from the catalytic system by centrifuging and loss of activity was negligible when the catalyst was recovered in four consecutive cycles. The effects of operational various factors such as catalyst amount, initial dye concentration and contact time on degradation of methyl orange were investigated. Optimization results showed that maximum degradation of methyl orange efficiency 98.6 % was achieved at the optimum conditions.

ZnO Semiconductor Nanoparticles and Their Application in Photocatalytic Degradation of Various Organic Dyes

“…The radicals then attack the CH 3 -N-CH 3 group, decomposing the CH 3 group. Subsequently, one of the aromatic rings is released, and some intermediate steps take place, to generate the final by-products, such as CO 2 and H 2 O [89][90][91]. Finally, the RhB degradation process begins when the double bond of the unsaturated chromophore is attacked by the O * 2 and OH − radicals until it is broken.…”

“…This process occurs until complete mineralization is achieved, and CO 2 and H 2 O remain as the final molecules. 92,93 In the case of the mixture of dyes, the degradation completes in 90 min as shown in Figure 12c. It is further mentioned that the peak of MO in the mixture is not strong due to the highly intense peak of the RhB dye and MB dye.…”

“…Most of the homogeneous catalysts have high activity and selectivity [26,27], however, heterogeneous ones can be easily handled, separated and reused. The potential advantage of heterogeneous catalysts allows the development of environmentally benign processes in both academic and industrial environment [28,29]. In recent years, among the various heterogeneous catalysts, magnetic nanoparticles (MNPs) with high surface area and their unique magnetic properties [30] have been widely applied in various chemical reactions [31][32][33][34][35][36][37].…”
