Abstract
- Visible light driven photocatalysts based on crystalline microporous metal halogenides received much less attention compared with dense or composite oxide semiconductors. Using the well-known photosensitive transition metal-complexes [TM(2,2-bipy) <subscript>3</subscript> ] <superscript>2+</superscript> (TM=Fe, Co, Ni, Ru) as templates, a special three-dimensional (3D) metal halogenide framework of [TM(2,2-bipy) <subscript>3</subscript> ]Cu <subscript>4</subscript> Br <subscript>6</subscript> was designed with [Cu <subscript>4</subscript> Br <subscript>4</subscript> ] cluster as 4-connected node. These microporous materials feature narrow band gaps and stable visible light driven photocatalytic properties including water reduction to provide H <subscript>2</subscript> and photodegradation of organic pollutants. The study of electronic band structure shows that the TM complexes effectively prevent the recombination of photo-induced electron/hole pairs leading to excellent photocatalytic activity and photochemical stability. This work represents the first 3D microporous metal halogenides used as visible light driven photocatalyst to provide hydrogen energy.<br /> (© 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.)
