a, Long-term H2 evolution from pure water (top) and seawater (bottom) using Glass-PC, untreated SVG-PC and SVG-PC PC sheets. Photocatalytic measurements were performed under AM1.5G irradiation for 22 h each cycle. The reactor was purged with N2/CH4 for 15 min before each cycle. b, Photograph of the assembled reactor containing a 25 cm2 SVG-PC sheet and artificial seawater. c, Time course of H2 and O2 evolution via the water splitting reaction using a 25 cm2 SVG-PC sheet over artificial seawater (22 h). d, Outdoor set-up for integrated H2 evolution and clean water production using the SVG-PC sheet with river water. e, Integrated H2 evolution and clean water production rate under simulated and natural sunlight. The photocatalytic experiments were performed under AM1.5G irradiation and natural sunlight for 4 and 2 h, respectively. The data are presented as mean values ± SD for experiments performed in duplicate (n = 2).
