Anatase TiO2 is a classic photocatalyst, but its 3.2 eV band gap drinks only UV light. Bismuth's filled 6s orbitals shrink the effective gap so absorption shifts toward visible light. No measured band gaps are claimed. Based on the paper: Theoretical and Experimental Studies on Electronic Structure and Optical Properties of Bi-doped Anatase TiO2; Z. Ma, F. Ren, Z. Yang, A.A. Volinsky; Optik, 2021, Vol. 241 (article 167107). Hosts Elena and Marcus. AI-generated voices.
