Published: March 4, 2023

Graphite phased carbon nitride (g-C3 N4 ) has attracted extensive attention attributed to its non-toxic nature, remarkable physical-chemical stability, and visible light response properties. Nevertheless, the pristine g-C3 suffers from rapid photogenerated carrier recombination unfavorable specific surface area, which greatly limit catalytic performance. Herein, 0D/3D Cu-FeOOH/TCN composites are constructed as photo-Fenton catalysts by assembling amorphous Cu-FeOOH clusters on 3D double-shelled porous tubular (TCN) fabricated through one-step calcination. Combined density functional theory (DFT) calculations, synergistic effect between Cu Fe species could facilitate adsorption activation of H2 O2 , separation transfer charges effectively. Thus, acquire a high removal efficiency 97.8%, mineralization rate 85.5% first-order constant k = 0.0507 min-1 for methyl orange (MO) (40 mg L-1 in reaction system, is nearly 10 times 21 higher than those FeOOH/TCN (k 0.0047 TCN 0.0024 ), respectively, indicating universal applicability desirable cyclic stability. Overall, this work furnishes novel strategy developing heterogeneous based nanotubes practical wastewater treatment.
