(a) Effect of rGO loads on the degradation of RhB dye by different photocatalysts, (b) UV-vis absorption spectra of RhB for NTG5 nanocomposite as a function of irradiation time, (c) Relation between irradiation time and ln(c/c0) and (d) Pseudo first-order rate constants for photocatalytic degradation experiments of RhB with different photocatalysts. Here, the solution pH = 7
