“…Unfortunately, Cu(II) precipitates in relatively low pH values, as compared to other transition metals, thus limiting significantly the possibility of depositing adequate amounts on TiO 2 through an adsorption process. 417 Bleam and McBride 407 studied the deposition of Cu(II) on titanium oxide using electron spin resonance (ESR) spectroscopy. They found that adsorption of Cu(II) on the surface of titanium dioxide begins at pH = 2 with the occupation of isolated sites having relatively high crystal fields.…”

“…Studies on the deposition of Cu­(II) on titanium oxide are also not abundant in the literature. Cu­(II) is present as an octahedral aqua complex Cu­(H 2 O) 6 2+ in the copper nitrate aqueous solutions usually used in the synthesis of copper supported catalysts. Unfortunately, Cu­(II) precipitates in relatively low pH values, as compared to other transition metals, thus limiting significantly the possibility of depositing adequate amounts on TiO 2 through an adsorption process …”

“…Ωστόσο, οι μελέτες της εναπόθεσης των ειδών Cu(ΙΙ) στην επιφάνεια του TiO 2 είναι πολύ περιορισμένες στη βιβλιογραφία [43][44][45][46][47][48][49][50][51][52][53]. Τα ιόντα του χαλκού Cu(II) εμφανίζονται στα υδατικά του διαλύματα ως οκταεδρικά υδατικά σύμπλοκα…”

“…[Cu(H 2 O) 6 ] 2+ , ενώ για τη σύνθεση των στηριγμένων καταλυτών χαλκού χρησιμοποιούνται συνήθως νιτρικά διαλύματά του. Δυστυχώς, ο Cu(II), συγκριτικά και με άλλα μέταλλα μετάπτωσης, καταβυθίζεται ως ίζημα σε σχετικά χαμηλές τιμές pH, καθιστώντας έτσι αρκετά μικρό το ποσοστό εναπόθεσης του στην επιφάνεια του TiO 2 , όταν αυτό επιτυγχάνεται μέσω προσρόφησης [53]. Cu(II) στην επιφάνεια του ανατάση [45].…”
