Fig. 5. Highly selective and high-performance osmotic power of UiO-66-NH2@ANM.

Fig. 5

The effect of anion salt types on the (A) current density, (B) power density, and (C) short-circuit current (Isc) of UiO-66-NH2@ANM generated in 1000 mM/10 mM concentration gradient. The maximum power densities with Br−, Cl−, NO3−, and SO42− were ~26.8, 11.0, 0.0216, and 0.0497 W/m2, respectively. (D) Comparison of the output osmotic powers between the subnanoscale UiO-66-NH2@ANM and the nanoscale ANM (with pore diameter of 25 nm) in different types of salts. (E) The selectivity ratios of the subnanoscale UiO-66-NH2@ANM and the nanoscale ANM were calculated on the basis of their output powers in various salt systems shown in (D). UiO-66-NH2@ANM can exhibit an unprecedented Br−/ NO3− selectivity of ~1240. (F) Schematic depiction of the anion-selective property of subnanoscale UiO-66-NH2@ANM based on the size exclusion effect.
