Sonochemical synthesis and characterization of Ho-Cu-O nanostructures and their application as photocatalyst for degradation of water-soluble organic pollutants under UV light

Recent progress on sonochemical production for the synthesis of efficient photocatalysts and the impact of reactor design

“…The combination of light irradiation and ultrasonic waves in heterogeneous catalysis is a technique that is used for the preparation of active and efficient photocatalysts [10] . An extensive amount of research has been conducted for the synthesis of different photocatalysts utilising sonochemical methods and many of them were related to environmental remediation applications, focusing on wastewater treatment for the decomposition of hazardous and toxic substances and for the removal of dyes [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] . Therefore, there is a great need to develop novel catalysts by applying ultrasonic waves created by the ultrasounds to act as a source of energy to convert the reactants to products in ways that do not occur otherwise.…”
