Advantages

11.4× faster degradation

The hydrogen-bond network promotes dense nucleation and inhibits overgrowth, yielding small AgBr with a surface hydrogen-bond layer that markedly enhances degradation kinetics.

Simultaneous H₂O₂ production

H₂O₂ is produced during pollutant degradation, coupling removal with chemical synthesis without extra sacrificial agents.

Stable over 10 cycles

After 10 cycles, the catalyst retained 94.92% of its initial activity, indicating robust stability.
