Photocatalyst comprising TiO<sub>2 </sub>and activated carbon made from date pits |
| 摘要 |
A photocatalyst is provided that comprises activated carbon produced from date pits, impregnated with TiO2. The activated carbon can have a porous surface that can attract and trap pollutants flowing in air or water. The photocatalyst can be made by a method that includes preparing activated carbon by calcining date pits to form a precursor material, and then impregnating the precursor material with titanium dioxide. |

1. A method consisting essentially of:
contacting date pits with a phosphoric acid solution having a phosphoric acid concentration of from about 1% by weight to about 30% by weight, to form treated date pits; drying the treated date pits to form treated, dried date pits; heating the treated, dried date pits under a nitrogen blanket and under conditions to cause the treated, dried date pits to thermally decompose and form activated carbon; and pulverizing and screening the activated carbon. |
