To investigate the photoactivity of brown F-TiO 2Àx /MCF, F-TiO 2Àx /MCF, and
hydrogen-doped TiO 2 (H-TiO 2Àx ), these samples were measured for the degradation
of methylene blue (MB) under simulated solar light irradiation using an AM 1.5 air
Fig. 3.7 (a) Solar light-driven (with an AM 1.5 air mass filter) photocatalytic water splitting for H 2
generation and the cycling measurements of F-TiO 2Àx /MCF; (b) photocatalytic activities for
degradation of MO induced by simulated solar light; (c) a comparison of photocatalytic decomposition of MB by F-TiO 2Àx /MCF, blank H-TiO 2Àx , and other catalysts under simulated solar light
irradiation (with an AM 1.5 air mass filter); (d) cycling tests of solar-driven photocatalytic activity
of F-TiO 2Àx /MCF for the degradation of MB; (e) transient photocurrent responses of F-TiO 2Àx /
MCF in 0.5 M Na 2 SO 4 aqueous solution under various irradiation conditions (UV light, < 380 nm
filter; visible light, > 420 nm filter); (f) comparison between the solar light-driven photocurrent and
the sum of the photocurrent of F-TiO 2Àx /MCF under UV and visible light irradiation. (Reprinted
