Abstract

Η εφεύρεση αφορά μία μέθοδο παρασκευής φωτοκαταλύτη αποτελούμενο από οξείδιο του τιτανίου με προσμίξεις μεταλλικού στοιχείου του τομέα d του περιοδικού πίνακα, π.χ. μαγγανίου, και στοιχείων και προσμίξεις μεταλλικού στοιχείου του τομέα p του περιοδικού πίνακα, π.χ. αργιλίου. Η μέθοδος παραγωγής περιλαμβάνει α) την παρασκευή μίγματος με την προσθήκη μεταλλικών στοιχείων ή ενώσεων σε διάλυμα που περιέχει τιτάνο, όπου τα μεταλλικά στοιχεία ή ενώσεις περιλαμβάνουν τουλάχιστον ένα μεταλλικό στοιχείο ή ένωση μεταλλικού στοιχείου του τομέα d του περιοδικού πίνακα, κατά προτίμηση μαγγανίου, και ένα μεταλλικό στοιχείο ή ένωση μεταλλικού στοιχείου του τομέα p του περιοδικού πίνακα, κατά προτίμηση αργιλίου, β) την επεξεργασία του μίγματος μετά την προσθήκη των μεταλλικών στοιχείων ή ενώσεων και γ) την παραλαβή του φωτοκαταλύτη που περιέχει διοξείδιο του τιτανίου με προσμίξεις ενός τουλάχιστον μεταλλικού στοιχείου του τομέα d του περιοδικού πίνακα και ενός τουλάχιστον μεταλλικού στοιχείου του τομέα p του περιοδικού πίνακα. Η δραστικότητα ενός φωτοκαταλύτη υπό ηλιακή ακτινοβολία και τεχνητό ορατό φως το καθιστά κατάλληλο για εφαρμογές τόσο σε εσωτερικούς όσο και σε εξωτερικούς χώρους.
