When pillared clay(PILC) is used as the catalyst in Fenton oxidation process,the shortcomings existing in Fenton method such as catalysts easily loss,low pH value range are resolved,while maintaining the removal rate of organic pollutant maintained in Fenton method.The new advances in PILC are reviewed in this paper.The studies on PILC,alone or combined with other techniques such as ultraviolet ones applied in catalytic heterogeneous Fenton of organic pollutants in wastewater,are summarized.The catalytic mechanism of PILC when used as the catalyst in heterogeneous Fenton process is analyzed.Aiming at the current problems,its development direction in future studies is proposed combined with the actual demands.
