Studies on Preparation and Photocatalyzed Sterilization of Fullerene Derivatives

A normal oxygen molecule when going through a Al_(2)O_(3) molecular sieve containing fullerene chlorine-argent amine complex could be changed into an active singlet oxygen ~(1)O_(2)under the irradiation of Xe lamp.The results showed that this type of active oxygen ~(1)O_(2)was of distinct ability to sterilize some bacteria,such as aeromonas,staphylococcus aureus and vibrios.The molecular mechanism from ~(3)O_(2) to ~(1)O_(2)was discussed_()and the singlet oxygen ~(1)O_(2)has been shown to possess apoptosis activity for cells.
