Hydrogen-bonded organic frameworks for environmental remediation and energy applications: A bibliometric analysis of research progress and prospects

Hydrogen-bonded organic frameworks (HOFs) are widely used in environmental and energy fields because of their high crystallinity, solution processability, and easy regeneration. Although there have been some reviews focusing on the specific environmental or energy applications of HOFs, a comprehensive research summary and analysis of research trends across the entire field is still lacking. To facilitate the advancement of HOFs, a bibliometric analysis method was used to examine all relevant literature on the subject. Initially, the general bibliometric distribution of the dataset by year, country, institute, reference source, and research focus are determined. Subsequently, the research hotspots covering adsorption, separation, sensing, catalysis, and energy storage are thoroughly explored. To conclude, an analysis of the potential opportunities and obstacles that lie ahead for HOFs is presented, offering a novel perspective to propel their advancement in the fields of environmental remediation and energy utilization.
