Boron Concentration Trends: Among the five photocatalysts, a notable trend was observed in the boron concentration. Boron, known for its electron-deficient nature, can introduce localized states in the band gap of the photocatalyst, thereby affecting the charge carrier dynamics. The increase in boron concentration from one atomic percent to two suggests an attempt to modulate the electronic properties of the photocatalyst. This increment could potentially enhance the photocatalytic activity by facilitating charge separation and reducing recombination rates.
