Several stannosilicates were synthesized and physicochemical characterized by X-ray powder diffraction (XRD), scanning electron microscopy with energy dispersive X-ray spectrometry (SEMEDS), Brunauer–Emmett–Teller (BET)-N2 surface area analysis and solid-state magic-angle spinning nuclear magnetic resonance (MAS NMR 29Si and 119Sn nuclei) techniques. The experimental results for enzymes immobilization were promising, especially for a nickel ion-exchanged metallostannosilicate, which were able to immobilize 82 ± 6% of Thermomyces lanuginosus lipase and also kept a high enzymatic activity (42 ± 3 U mg–1 ). Systematic catalytic reactions for conversion of refined palm oil (Elaeis guineensis) using some of these stannosilicates enzymes complexes yielded 63.3 ± 0.7% of FAEEs. It is worth noticing that, when the transesterification reaction was performed with (a) the as-made stannosilicate without enzymes and (b) the equivalent amount of immobilized Thermomyces lanuginosus lipase in its free form, the FAEEs yield sharply decreased to < 5.0% and 6.3 ± 0.3%, respectively. This result is a clear evidence of a synergistic effect among the metallo-stannosilicates and the immobilized enzymes. 2021 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42966701008 https://www.redalyc.org/journal/429/42966701008/ https://www.redalyc.org/journal/429/42966701008/html/ https://www.redalyc.org/journal/429/42966701008/42966701008.epub https://www.redalyc.org/journal/429/42966701008/movil https://doi.org/10.26850/1678-4618eqj.v46.1SI.2021.p75-89 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Vol.46 |
