Photocatalysts capable of decomposing pollutants using solar energy are gaining significant attention. However, the commonly used photocatalyst TiO₂ suffers from drawbacks such as poor responsiveness to visible light and low photocatalytic efficiency. To address these limitations and enhance visible light absorption, this research focuses on TiC-TiO₂, which incorporates C atoms into the TiO₂ structure. By combining it with P-doped C₃N₅, the recombination of photo-induced electron-hole pairs is suppressed, resulting in a visible light-responsive photocatalyst. TiC-TiO₂/C₃N₅, expected to exhibit high activity, was synthesized under various conditions to evaluate its physical properties and photocatalytic performance.
