Abstract
Prussian blue analogs (PBAs), a type of metal–organic frameworks (MOFs), have attracted much attention because of their large specific surface area, high porosity, easy synthesis, and low cost. This paper presents the first review of PBAs by applying the bibliometric visualization software CiteSpace. The co-occurrence, co-citation, and clustering analysis of 2214 articles in the Web of Science database on the topic of “Prussian blue analogs” over the past 20 years were performed. The results provide a comprehensive overview of the evolution of the research hotspots for this material, and most importantly, it is identified that the research hotspots and trends for PBAs materials are concentrated in the environmental and energy fields. For example, the material is used as an adsorbent or catalyst to reduce pollutants, produce clean energy, or for energy storage applications such as batteries or supercapacitors. Finally, some outlooks are provided on the future research trends of this material in the environmental and energy fields, presenting the challenges faced by this material. For instance, the conductivity and corrosion resistance of the material needs to be improved and secondary contamination should be decreased or even avoided. It is believed that this paper would provide a comprehensive, systematic, and dynamic overview of the research of PBAs, and promote the future research of PBAs in the fields of environment and energy.
