Improving photocatalytic activity in visible light by synthesizing g-C۳N۴/TiO۲ nanocomposites

Graphitic carbon nitride (g-C۳N۴) and titanium dioxide nanotubes (TNTs) have attracted considerable attention as promising photocatalytic materials due to their environmental compatibility, low cost, and excellent chemical stability. This study revealed that the g-C۳N۴/TNT composite exhibits lower charge-transfer resistance and improved separation efficiency of photogenerated electron-hole pairs compared to bare TNT electrodes. The formation of the heterojunction between g-C۳N۴ and TNT effectively suppresses the recombination of charge carriers and extends the photocatalytic response into the visible-light region. These results demonstrate that coupling g-C۳N۴ with TiO۲ nanotubes is an effective strategy for developing efficient and stable photocatalysts.
