The system displays a good peroxidase-like activity and catalyzes to the oxidation of 3,3',5,5‘-tetramethylbenzidine (TMB) by H2O2. KM values were calculated between 0.04 and 0.08 mM for different (CeO2/SBA-15)x catalyst system, the results demonstrates that the combination of these materials displayed a good affinity to TMB substrate, consequently improving the colorimetric assay, due to uniform mesostructures of SBA-15 and their high surface areas. A detailed study of synergistic effects between CeO2NPs and SBA-15 support were held in order to understand how these effects can improve the colorimetric assay. Additionally, high resolution transmission electron microscopy (HR-TEM), energy dispersive X-ray spectroscopy (EDX), Raman spectroscopy, thermogravimetric analysis (TGA), small angle X-ray scattering (SAXS) and textural properties were utilized for characterization of the prepared catalysts systemsCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPFechadoUNIVERSIDADE ESTADUAL DE CAMPINASOliveira, Larissa Helena de, 1983-Barros, Anerise de, 1986-Pinto, Lidiane de Oliveira, 1994-Oliveira, Cristine Santos de, 1990-Kubota, Lauro Tatsuo, 1964-Sígoli, Fernando Aparecido, 1972-Mazali, Italo Odone, 1972-2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/20.500.12733/1670836OLIVEIRA, Larissa Helena de et al.
