This tutorial review illustrates opportunities for the resolution of structure–function relationships to aid in the development of new materials for solar energy conversion using a combination of spectroscopy and catalysis measurements with X-ray scattering analyses to provide in situ structural characterization of solar fuels catalysts. As an example, the use of molecular cobaloxime catalysts in bimolecular and supramolecular photocatalysis schemes for proton reduction is briefly reviewed. These highlight the need to develop new modular, hierarchical, self-healing supramolecular architectures for solar fuels catalysis. Examples of the X-ray scattering structural analysis of amorphous materials in the context of photocatalytic function are discussed in detail.
