Semiconductor-attapulgite composites in environmental and energy applications: a review

Abstract Attapulgite, with abundant reserves, low price, a special structure, excellent adsorption, thermal stability, and catalytic performance, is often used as a catalyst or catalyst support, offering broad development prospects. In order to understand and fully utilize attapulgite resources, this paper introduces the common preparation methods of attapulgite and explores the effects of different modification methods ( e.g. thermal modification, acid modification, etc.) on attapulgite performance. The article focuses on the current status of semiconductor-attapulgite composites in the fields of wastewater treatment, air pollution, and energy, and briefly describes examples of their applications in other fields. Finally, the development prospects of the composites in the field of environment and energy are summarized, and the challenges are discussed.
