Recently, water pollution caused by dyes and organic pollutants (such as methyl orange and methylene blue) has been produced through industrial textiles, leather, pharmacy, etc., which has become a serious ecological issue. [1][2][3] Consequently, several technologies, such as chemical precipitation, adsorption, and membrane, have been applied to treat these toxic organic contaminants from water. 4-6 Among these used methods, photocatalysis has attracted extensive attention due to the unique advantages such as low energy consumption, easy fabrication, repeatable process, high removal efficiency, and limited chemical requirement. 7 In the photocatalysis process, sunlight is used as a source of energy; the process begins with absorbing a photon and continues by generating electrons and holes. The electron and holes pairs react with oxygen, water, and produce active radicals, which could destroy organic pollution in water. 8,9 That is
