a Photocatalytic OWS of BTO in different etching time evolution processes under UV–Vis light using 300 W xenon lamp. b AQE of BTO-2 wavelength dependence of photocatalytic activity. Conditions: 0.12 g catalyst, 0.5 wt% Rh, 100 mL deionized water, and 300 W xenon lamp. c Time course of OWS of BTO-2 under simulated sunlight (AM 1.5 G). The solid line is linear fitting for H2 (R2 ≥ 0.999) and O2 evolution (R2 ≥ 0.999). d Stability of photocatalyst of BTO-2 with the same condition as (a). The solid line is linear fitting for H2 (R2 ≥ 0.999) and O2 evolution (R2 ≥ 0.999). e Comparison of structure-activity relationship of photocatalytic water decomposition properties. f Comparison of the STH and produced hydrogen under xenon lamp over the BTO photocatalyst with those of reported one-excitation photocatalysts.
