An Amine‐Functionalized Zirconium Metal–Organic Polyhedron Photocatalyst with High Visible‐Light Activity for Hydrogen Production

Abstract Metal–organic polyhedra (MOPs) are promising candidates for many potential applications; however, their use as photocatalysts for hydrogen production has yet to be developed. Herein, the photocatalytic performance of a water‐stable Zr‐MOP, ZrT‐1‐NH 2 , was evaluated, for the first time, through photocatalytic hydrogen evolution under visible‐light irradiation. ZrT‐1‐NH 2 shows clearly enhanced photocatalytic activity (510.42 μmol g −1 h −1 ) for hydrogen production, in comparison with that of other homogeneous crystalline materials. If platinum nanoparticles were introduced into the photocatalytic system, the hydrogen production efficiency of ZrT‐1‐NH 2 could be further improved. For ZrT‐1‐NH 2 , the conspicuous improvement in photocatalysis can be attributed to efficient electron–hole separation, targeted electron transfer, and excellent recombination suppression. Furthermore, ZrT‐1‐NH 2 shows excellent stability during photocatalytic hydrogen evolution over five continuous runs. This work illustrates that MOP‐based photocatalysts hold promise for broad applications in the domain of clean energy.
