In recent years, bismuth tungstate (Bi2WO6) has been widely researched in the photocatalytic area due to its unique crystal structure and suitable bandgap. In this study, a comprehensive summary of Bi2WO6-based photocatalyst research from 2007 to 2022 was provided using bibliometric analysis. The study was conducted based on the Web of Science Core Collection Database and a dataset of 2064 publications retrieved. The bibliometix R-package and CiteSpace software were used for bibliometric analysis and science mapping. The network of the relationships among countries, journals, organizations, authors, and keywords related to investigated topic and subtopics were analyzed and discussed. Results showed that China has been playing an important role in this research area and also has a close cooperative relationship with other countries. Highly-cited emergent words indicated that improving the photocatalytic performance of Bi2WO6-based nanomaterials is the main research topic. In addition, the synergistic effects of photocatalysis and adsorption have also become a research hotspot for improving catalytic efficiency. The results will provide a reference for researchers for gaining a deeper understanding of Bi2WO6-based photocatalysts.

“…The band position determines the migration and recombination of photo-generated electrons and holes in the interaction with individual components of the composite photocatalyst. The valance band (VB) and conduction band (CB) of AgI/LaFeO 3 /g-C 3 N 4 can be appraised by the empirical Equations (2) and 3as shown below [29] E VB = X-E e + 0.5E g (2) E CB = E VB − E g (3) where E VB and E CB were the VB and CB edge potential respectively, X was the semiconductor absolute electronegativity, represented as the absolute electronegativity of the constituent atoms, and E e was the energy of free electrons on hydrogen atoms valuing 4.5 eV, approximately. E g was symbolizing as the bandgap belonging to the semiconductor material.…”

AgI/MFeO3/g-C3N4 (M = Y, Gd, La) nano sheet–sphere–sheet photocatalysts were synthesized by a simple ultrasound-assisted hydrothermal approach. We characterized the microstructure, surface morphology, and optical absorption capacity of the obtained samples. According to the characterization results, AgI/MFeO3/g-C3N4 (M = Y, Gd, La) nano sheet–sphere–sheet photocatalysts were successfully obtained. MFeO3 nanospheres and AgI nanosheets were dispersed evenly on the surface of g-C3N4 nanosheets. AgI/MFeO3/g-C3N4 showed remarkable photocatalytic. Especially, 95% of NOF was photodegradated over AgI/LaFeO3/g-C3N4 within 3 h and the higher photocatalytic performance still remained after six cycles. Additionally, The N2 adsorption–desorption isotherms of AgI/MFeO3/g-C3N4 showed that AgI/LaFeO3/g-C3N4 possessed the highest specific surface area (79.32 m2/g). The result of scavenging experiment revealed that ·O2−, h+, and ·OH were the main roles in the photodegradation process. Benefitting from the nice energy band matching, MFeO3 acted as the center of photogenerated electrons migration and separation provided more direct electron channels. This work proposes an effective approach for the design and configuration of dual Z-scheme photocatalysts to accomplish the removal of organic contaminants based on g-C3N4.
