Light work: Open-framework chalcogenides are efficient visible-light photocatalysts for the reduction of water to hydrogen. These materials contain 3D covalent superlattices built from nanosized supertetrahedral clusters (see picture). Unlike dense semiconductors, they allow the easy incorporation of dye sensitizers within their channels, which can further enhance their photocatalytic response in the visible-light region.
