Molybdate, Patents, Articles, Technological Prospecting


Among the several applications of molybdates, the photocatalysis is a highly appealing process with multiple applications, mainly in the fields of pollution removal.  In view of this, the main objective of this work was to study the potentialities and the evolution of the technological features inherent to patent deposits, and panorama of publications of articles on molybdates, as well as the related photocatalytic a properties, specifically in the range years from 2000 to 2017. The study was performed using information from the Web of Science, SciELO, European Patent Office (EPO), United States Patent and Trademark Office (USPTO), Derwent Innovations Index, and the database of the National Institute of Industrial Property (INPI) of Brazil. The research has shown growth in the number of patents and articles over the years. Brazil is well positioned in the world ranking of publications of articles containing photocatalytic properties of molybdates, but does not display patents filed with INPI. Regarding the world stage, the results indicate a promising area with significant growth in the number of patents and scientific articles.
