Acid Blue 113 was chosen as the model dye because the two azo bonds in its chemical structure, as shown in Fig 1 , make it particularly recalcitrant. To make dye mixture, Methyl Orange and Reactive Black 5 were selected. All reagents were of analytical grade and used without any further purification. Dyes were procured from Sigma-Aldrich while 30% (wt/wt) H2O2 was purchased from Merck. Iron chloride, 2,2´-bipyridine, 2-propanol, and ethanol were obtained from Merck and used for the preparation of the heterogeneous catalysts. ZSM-5 (SiO2/Al2O3 mole ratio: 50) was purchased from Zeolyst International. The initial pH of the synthetic dye solution was adjusted using 0.5 M H2SO4 and 1 M NaOH (Merck). Quantitative estimation of H2O2 concentration at the end of the experiment was accomplished using peroxide strips.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
