Fig. 2. Photocatalytic performance and photoelectrochemical analysis. (a) Photocatalytic performance of USTB-7, USTB-9, and USTB-44–USTB-47 (5.0 mg catalyst in 50.0 mL pure water, l > 420 nm). (b) Performance comparison of USTB-7, USTB-9, and USTB-44–USTB-47. (c) The photocatalytic performance of USTB-46 has a different quality but the same catalyst concentration (1.0 mg/10.0 mL; the data is the average of two tests). (d) Performance comparison of USTB-46 (2.5 mg catalyst in 25.0 mL pure water, l > 420 nm) with state-of-the-art photocatalysts reported thus far. (e) UV–Vis diffuse reflectance absorption spectra (DRS). (f) Experimental energy levels. (g) Photocurrent responses. (h) Electrochemical impedance spectra.
