Highly crystalized TiO2 layers were successfully composited on Cu2O photocathodes.
- class="label">•
Crystallization of TiO2 with no damage to Cu2O by laser was due to nanosecond-scale thermal effect.
- class="label">•
The obtained TiO2/Cu2O photocathodes had a high chemical stability toward water reduction.

The composition process is applicable for every photoelectrode to raise chemical stability.
