Key Points

The aim is to evaluate the effectiveness of mechanical and photochemical methods for phenol degradation.
Used low liquid-assisted grinding (LAG) with sequential H₂O₂ addition for mechanical activation.
Investigated the effects of photochemical excitation on phenol degradation efficiency.
Utilized P25 TiO₂ as the catalyst throughout the process.
Significantly higher degradation rates of phenol observed under photomechanocatalytic conditions.
P25-TiO₂ showed improved reactivity leading to effective phenol removal.
The combination of mechanical activation and photochemical excitation resulted in enhanced degradation efficiency.
