Understanding metal-organic frameworks for photocatalytic solar fuel production

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