Characterization of PSB. A SEM image of PSB. B TEM image of PSB. Scale bar is 1 μm. C UV−Vis−NIR absorption spectra of PSB. D H2 released at different concentrations. E H2 releasing behavior produced by PSB (107 CFU/mL) under various power intensities (12, 13 and 14 A) and F various glucose concentration (0, 15 and 30 g/L). G H2 production of PSB by irradiation with power “On” or “Off” alternately. H The pictures of H2 production in different times of radiation
