Discussion

Novel Triply Periodic Minimal Surface (TPMS) reactors demonstrate enhanced photocatalytic performance with TiO2 in water treatment.

The FRD-type TPMS photocatalytic reactor achieved 95.36% degradation efficiency of methylene blue under rotational flow.
Rotational flow enhanced degradation performance, achieving a sixfold increase in average flow velocity compared to horizontal flow.
Computational Fluid Dynamics simulations helped analyze flow characteristics in these innovative reactors.
Efficiency improved to 96.7% after five degradation cycles, showcasing long-term stability in photocatalytic water treatment.

Chen et al. (2025) studied this question.
