Synthesis of Dendritic Polymer for Hydrogen Peroxide Production and Organic Pollutants Degradation Under Visible Light Conditions

Graphical A dendritic nano-polymer was synthesized and used as a photocatalyst for H 2 O 2 production and Tetracycline/ Rhodamine B degradation under a 36 W incandescent bulb. The yield of H 2 O 2 is 8.4 mg g −1 h −1 , and the photocatalytic degradation rates of Rh B and TC can reach 93.9 % and 72.92 %, respectively. A process for photocatalytically synthesizing hydrogen peroxide while simultaneously degrading organic pollutants is of interest. In this study, a dendritic nanopolymer was synthesized and utilized as a photocatalyst for the production of hydrogen peroxide, which was then used in tandem with the degradation of Tetracycline (TC) and Rhodamine B (Rh B) organic pollutants under a 36 W incandescent bulb. The yield of H 2 O 2 was measured at 8.4 mg g −1 h −1 , with photocatalytic degradation rates of 93.90 % for Rh B and 72.92 % for TC. The degradation kinetics of TC and Rh B by the dendritic polymer were found to follow pseudo-first-order kinetics, and a higher affinity for degradation was observed for Rh B. The photocatalytic degradation mechanism of TC in a Fenton-like system was attributed to an oxidation system involving hydrogen peroxide and ferrous ions.
