  • Patent number: 9950977
    Abstract: Polyhydroxyfullerenes (PHFs) having enhanced electron scavenging capabilities have a ratio of non-hydroxyl functional groups to hydroxyl functional groups that is less than or equal to 0.3. When combined with a semiconductor photocatalyst, such as titanium dioxide nanoparticles, the PHFs provide a photocatalyst for degradation of chemical and biological contaminates with an efficiency of at least twice that of titanium dioxide nanoparticles free of PHFs. The PHFs are included in these catalysts at a weight ratio to titanium dioxide of about 0.001 to about 0.003, whereas significantly lower and higher ratios do not achieve the highly improved photodegradation capability. PHFs outside of the desired structure are shown to be of little value for photodegradation, and can be inhibiting to the photocatalytic activity of TiO2. The enhanced electron scavenging PHFs can be employed as a component of materials for solar cells, field effect transistors, and radical scavengers.
