Removal of reactive blue 250 dye from aqueous medium using Cu/Fe catalyst supported on $ Nb_{2} $$ O_{5} $ through oxidation with $ H_{2} $$ O_{2} $

Abstract This study aimed to synthesize a new bimetallic Fenton catalyst using $ Nb_{2} $$ O_{5} $ as the support for the active metal species of copper and iron. The coprecipitation method was used to prepare the catalyst, characterized by several technical means. The efficiency of the material was evaluated in batch mode in the degradation of a reactive blue 250 textile dye in aqueous media, with the study of the critical variables for the process. The catalyst employed resulted in 80% decolorization of the RB dye under the experimental conditions of pH 3, [Catalyst]0 = 1.0 g $ L^{−1} $, [$ H_{2} $$ O_{2} $]0 = 200 mg $ L^{−1} $, [RB]0 = 10 mg $ L^{−1} $. It proved to be very active under natural sunlight in the photo-Fenton system. It was possible to regenerate it and use it in five Fenton reaction cycles, demonstrating its stability and the quality of niobium as support.Please confirm if all the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).
