Semiconductor photocatalytic technology has become an area of extensive research due to the extensive environmental contamination. Zeolitic imidazolate frameworks (ZIFs) are a distinct class of metal-organic frameworks that exhibit promise in the field of photocatalysis. This is attributed to their inherent porosity structure, versatile functionalities, rapid electron transfer rate, and excellent chemical-thermal stability are exhibited by this material. In addition, the photocatalytic performance of ZIFs and their derivatives can be greatly increased with the incorporation of active metals or semiconductor materials that act as light collecting centers or electronic mediators. Lately, there has been a growing focus on producing and utilizing materials under consideration are derived from the Co-zeolitic imidazolate framework (ZIF-67).), due to their remarkably great surface area, controllable pore diameter, and outstanding responsively to visible light. This article provides an exhaustive review of the use of ZIF-67-based heterojunctions in visible light-promoted photo-catalytic breakdown of organic dye contaminants. The review discusses and summarizes representative works, with particular emphasis given to the synergistic impacts and proposed mechanisms of the ZIF-67 composite photocatalysts in boosting photocatalysis process. Finally, the recent achievements and challenges in this discipline are discussed, and potential avenues for future investigation are suggested.
