Catalytic ozonation (OC) is a promising technology in terms of efficiency and energy cost as a treatment of industrial effluents that have pollutants of emerging concern, since it improves the oxidative capacities of ozone through catalysts that promote its decomposition and the generation of radicals oxidants species. This article studied the status and evolution of OC through a literature review and bibliometric analysis combined with the S curve technique to quantitatively analyze 1714 publications in SCOPUS and Scielo Index from 1973 to 2021. The results showed that (1) the number of publications worldwide started in 1973 to have 189 documents in 2021; (2) China is the country with the highest number of publications and annual citations (958 and 19088, respectively) and it is a central country in international cooperation networks; (3) the analysis of keyword co-occurrence showed that research has prioritized OC reaction mechanisms, kinetic expressions, the catalysts, and since 2016, the pilot scale application with other advanced oxidation technologies; (4) The compound with larger research is oxalic acid and since 1999 ibuprofen and atrazine; (5) in Latin America, Brazil is the country with the most publications (32) and with the largest number of international cooperation networks and (5) Applied Catalysis B: Environmental and The Journal of the Brazilean Chemical Society (Latin America) are the journals with the best quartile that publish on OC. Finally, the S curve indicated that OC is in a growth stage in terms of the scientific maturity, exhibiting great potential in R&D.
