Research Photocatalytic Water-splitting based on big data mining technology

Abstract

Visible photocatalytic water splitting is an effective way to solve the global energy and environmental crisis, and its green and environmentally friendly properties are worth researching. In this paper, we extracted 8395 articles from the core collection of Web of Science from 1991 to 2020. Visual analysis of the data by various software, such as Excel, Origin, Citespace V, reflected the following results. First, the number of related papers has increased exponentially, reaching a peak in 2018, with a total of 1508; next, among all countries, China has published the most papers and cooperated most closely with other countries; additionally, in terms of journals, Applied Catalysis B: Environment has the largest number of publications in the field of visible light catalytic cracking of water, and Journal of the American Chemical Society has the highest number of co-citations in this field, researchers can focus on these journals; finally, MAEDA K, ZHANG J, and WANG Y are ideal collaborators in this field. “Application and modification of graphite phase carbon nitride,” “application and modification of Z-scheme photocatalyst,” and “band structure engineering” are the hottest research frontiers in this field and represent the future development direction of this field.
