Prussian blue (PB) and Prussian blue analogues (PBAs), which are a family of coordination polymers (CPs), are considered excellent catalysts, and thus widely studied in the field of electrocatalysis. To date, numerous excellent studies on PBA-derived electrocatalysts have been reported. In contrast, in the field of photocatalysis, the exploration and reports on PBA and its derivatives are relatively scarce compared to electrocatalysis. However, in the past five years, an increasing number of PBA-derived photocatalysts has been reported in almost every field of photocatalysis. Due to their advantages of tailorable structures, favorable stability, low cost and simple preparation process, these materials show great potential in each field of photocatalysis. In this review, we summarize the latest developments in the synthesis and photocatalytic performance of PBA-derived photocatalysts. Our discussion is focused on PBA-derived photocatalysts in terms of photocatalytic hydrogen evolution, photocatalytic water oxidation, and CO₂ photoreduction. Subsequently, the design, catalytic performance and catalytic mechanism of PB/PBA-derived photocatalysts are discussed. Finally, the challenges and prospects in PB/PBA-derived materials for their application in photocatalysis and guiding principles for fabricating PBAs to realize distinguished activities are presented.
