Metal–Organic Framework (MOF) Compounds: Photocatalysts for Redox Reactions and Solar Fuel Production

2016

View full text Add to dashboard Cite

Metal-organic frameworks (MOFs) are crystalline porous materials formed from bi- or multipodal organic linkers and transition-metal nodes. Some MOFs have high structural stability, combined with large flexibility in design and post-synthetic modification. MOFs can be photoresponsive through light absorption by the organic linker or the metal oxide nodes. Photoexcitation of the light absorbing units in MOFs often generates a ligand-to-metal charge-separation state that can result in photocatalytic activity. In this Review we discuss the advantages and uniqueness that MOFs offer in photocatalysis. We present the best practices to determine photocatalytic activity in MOFs and for the deposition of co-catalysts. In particular we give examples showing the photocatalytic activity of MOFs in H2 evolution, CO2 reduction, photooxygenation, and photoreduction.

“…[13][14][15][16][17][18][19][20][21] MOFs have provided a highly tunable platform for designing single-site solid catalysts for a variety of catalytic reactions. [22][23][24][25][26][27][28][29] Unlike traditional inorganic porous materials, unlimited possible combinations of metal-oxo clusters and organic linkers allow access to reticular structures with tunable pore sizes and functional properties. The controllable nanospace in the framework of MOFs is a suitable candidate for a host of catalytically active species and will provide an accurately controlled reaction field.…”

A catalytically competent Cu species has been immobilized within the framework of a Zr-based metal−organic framework with bipyridine units, Zr-MOF-bpy, by a simple post synthetic modification method from CuBr2 (Zr-MOF-bpy-CuBr2) and used for the selective oxidation of cyclooctene to cyclooctene oxide. Zr-MOF-bpy was synthesized by a simple solvothermal method and was shown to have a UiO-type structure. Diffuse reflectance UV-vis and XAFS measurements have revealed that the immobilized Cu species has a square planar geometry of two N atoms and two Br atoms. Zr-MOF-bpyCuBr2 catalyzed the selective oxidation of cyclooctene to cyclooctene oxide with high activity and selectivity in the presence of tert-butyl hydroperoxide as an oxidant. In addition, the catalytic ability of Zr-MOF-bpy-CuBr2 was demonstrated to be superior to that of the corresponding homogeneous catalyst ((bpy)CuBr2). It was also confirmed that Zr-MOF-bpy-CuBr2 can be reused as a heterogeneous catalyst without significant loss of its activity and selectivity.

“…The resemblance between MOFs and bulk transition metal oxides encouraged more than a decade ago the first examples of photocatalytic MOFs. [11][12][13][14][15] Since then, frameworks based on Ti, [16][17][18] Zr, [19][20][21][22][23][24] Fe, 25,26 etc. have been reported for different artificial photosynthetic reactions (i.e.…”

Understanding metal–organic frameworks for photocatalytic solar fuel production

et al. 2017

View full text Add to dashboard Cite

The fascinating chemical and physical properties of MOFs have recently stimulated exploration of their application for photocatalysis. Despite the intense research effort, the efficiency of most photocatalytic MOFs for solar fuel generation is still very modest. In this highlight we analyse the current status of the field and stress the potential of advanced spectroscopic techniques to gain structural and mechanistic insight and hence support the future development of MOFs to harvest and store solar energy.
