“…The adsorption capacity of an ash depends strongly on its origin; therefore, detailed studies are required for individual specific industrial applications. In addition to their role as adsorbents, ashes can potentially be used as low-cost photocatalytic supports because they possess almost all the required characteristics, such as stability to light illumination, high surface area, and easy recovery (Borges et al, 2014;Katsika et al, 2018;Zeghioud et al, 2016). In addition, these ashes are inexpensive and mass-produced materials with exceptional suitability to be used in water remediation as membrane filters and photocatalysts (Borges et al, 2017;Ma et al, 2018;Ramírez-Franco et al, 2019).…”

Photocatalytic materials are currently intensively studied because of their high potential in UV and solar-light water purification. The photocatalysis is based on charge carrier generation and mobility of electron/hole pairs. Usually, a large amount of photoexcited charge it is lost by recombination, there are necessary coupled materials, highly active photocatalysts, and a very good electron acceptor semiconductorthat means composite material. There are several catalysts reported in the literature. Among the metal oxides such as TiO 2 , ZnO, SnO 2, and CeO 2 , CuO is extensively used in heterogeneous photocatalysis for degradation of organic compounds degradation. Its activity can be enhanced by several
