Fabrication of Flexible Cu-TiO₂ Nanosheet Photocatalysts on Carbon Cloth for Solar Hydrogen Production via a Self-Healing Cu Redox Loop

The development of sustainable photocatalysts for solar to hydrogen (STH) remains a central challenge in clean energy research. Here, binder-free Cu-doped TiO₂ nanosheets on conductive carbon cloth (Cu–TNS@CC) are fabricated...
