Construction of semiconductor-based membranes accommodates new routes for photothermal conversion and in-situ decomposing of pollutants in solar light-driven evaporation. In this work, a novel photocatalyst composed of MoO3-x, BiOCl, and carbon nanotubes was surficial deposited on cellulose acetate membrane. High capillary pressure ( -600 kPa) guaranteed an effective capillary rise of water from hydrophilic membrane matrix. The water was extruded into ultra-fine droplets with a saturation vapor pressure as high as similar to 1.75 x 10(5) Paand a heat flux as much as similar to 2.11 x 10(-3) W mm(-2). Moreover, the top-surficial film can harvest sufficient solar photons to generate charge carries, and the surface temperature of membrane can quickly increase to higher than 50 degrees C by thermalization through carriers relaxation, transference, and recombination on specific sites. Simultaneously, pollutants in water are efficiently decomposed by effectively separated charge carriers on designed spots. Synergistically, a steam generation rate of similar to 7.75 kg m(-2) h(-1) was acquired and an almost complete removal of RhB and toluene was achieved.
