Inverse Opal Sn2-xTiO4/TiO2 S-Scheme Heterojunction with Slow Photon Effect for Photocatalytic Hydrogen Production and Degradation.
Photocatalytic water splitting for hydrogen production is a crucial pathway for renewable energy conversion. However, conventional photocatalysts commonly face challenges such as low light absorption efficiency and severe recombination of photogenerated charge carriers. In this study, a Sn2-xTiO4/TiO2 S-scheme heteroju...
