In the growing search for inexpensive, renewable energy sources there has emerged a renewed interest in developing innovative photocatalysts able to effectively convert sunlight into storable chemical energy. Deviating from common inorganic semiconductors, Metal-Organic Frameworks (MOFs) have recently emerged as potential photocatalysts that display unique properties, such as large specific surface areas and wide structural versatilities. This presentation will explore current research in MOF-based materials for photoelectrolysis in hydrogen generation technologies. Specifically, research exploring the use of post-synthetic metal exchange (PSME) using Ce(IV) with the Zr-based MOFs UiO-66 and UiO-66-NH<sub>2</sub> will be a major focus. The Zr-based UiO MOFs stand out as exceptional candidates for photoelectrolysis because of their high thermochemical stability and tunable UV-Vis band gap. Differences in chemical composition introduced through PSME and their effects on chemical interactions and bulk material properties will be discussed in detail.
