Herein, reduced graphene oxide nanosheets (RGON) were electrochemically grown onto a carbon steel alloy from graphene oxide (GO)​ and the anti-corrosion performance of the RGON-deposited layers was evaluated.

Modification of CS/G by 1,8 ND containing two phenyl rings and two azo groups led to higher protection efficiency.

Ni-DMG/ZSM-5 zeolite was prepared by ion exchange and complexation procedures. FT-IR, XRD, SEM, TG, and DTG methods were used for characterization of the raw and modi�ed samples. e prepared composite was used as a catalyst in the photodegradation process of an aqueous solution methyl green (MG) dye under UV irradiation. e effect of key operating parameters such as catalyst dosage, temperature, the initial concentration of the dye, and pH of the samples was studied on the degradation extent of the dye. UV-Vis spectrophotometric measurements were performed for determination of the decolorization and mineralization extents. e optimal operation parameters were found as follows: pH = 9, temperature of 60 ∘ C, 0.6 g L −1 of the catalyst, and 40 ppm of the dye concentration. e Ni-DMG particles out of zeolite framework did not show signi�cant degradation efficiency. e degradation process obeys the �rst-order kinetic.
