Modified Activated Carbon and Its Application in Environmental Protection

Activated carbon (AC) is one of the widely used materials as catalyst and adsorbent. It has been known that there is a positive correlation between its porosity and capability, and that porosity structure and surface chemical properties are essential. In order to improve its properties, such as adsorption efficiency, adsorption selectivity and catalysis, it is important to adjust the porosity and change the surface chemical property. In this paper, some modified methods and the uses of the modified AC in pollution control are reviewed.
