Visible‐light photocatalytic degradation curves of MB by different catalysts

(a) Photocatalytic degradation of MB by P25, TNTs, Pd/TNTs nanocomposites (1 wt% of Pd) and Pd/TNTs nanocomposites (1 wt% of Pd) assisted by S. oneidensis MR‐1 (5 × 10⁶ CFU mL⁻¹), (b) absorbance curves of MB in the photocatalysis process by Pd/TNTs nanocomposites (1 wt% of Pd) assisted by S. oneidensis MR‐1 (5 × 10⁶ CFU mL⁻¹), (c) Photocatalytic degradation of MB by Pd/TNTs nanocomposites (1, 4 and 8 wt% of Pd) and Pd/TNTs nanocomposites (1, 4 and 8 wt% of Pd) assisted by S. oneidensis MR‐1 (5 × 10⁶ CFU mL⁻¹)
