Capturing photogenerated electrons and holes at the B/Cl co-modified rutile TiO2 nanorods during organic pollutant degradation

Abstract

Degrees for capturing photogenerated holes by residual chemically-adsorbed Cl as donators and electrons by increased amount of adsorbed O₂ as receptors after H₃BO₃ modification in rutile nanorods are quantitatively controlled based on the surface photovoltage measurements, suggesting that capturing electrons is dominant compared to capture holes in colorless pollutant degradation.
