Spatially Distributed Carbon Quantum Dots in TiO2 for Photothermal-Assisted Hydrogen Production from Seawater

Abstract

An efficient hydroxyl-rich carbon quantum dot-integrated TiO2 nanofiber system is developed for photothermal-assisted hydrogen production from seawater. Spatially distributed CQDs enable efficient heat utilization throughout TiO2, while the hydroxyl-rich surface maintains a proton-accessible interface for stable hydrogen production in seawater under complex ionic conditions.
