(a, c) Variation of residual concentration with time and (b, d) corresponding Langmuir-Hinshelwood plot for photocatalytic oxidation between (a, b) phenol and MB (c, d) phenol and Cr(VI) by Photo-Zn-Bent. Dotted line represents a bi-component photocatalytic system and solid line presents single component system. (e) Repeated use of Photo-Zn-Bent for pollutant removal from consecutive three cycles from both single component (MB, Phenol) and bicomponent (MB-Phenol and Phenol-Cr(VI)) pollutant systems
