Abstract
∼ 3.70 eV). The ASOet sample showed the highest performance (∼55% sulfamethoxazole degradation and 54% TOC mineralization) within 120 min. Thus, our work further reinforces the critical importance of particle morphology, which supersedes the overall band gap energy of the material, making visible-light excitation possible even for larger band gap materials.
