- Palladium nanoparticles from a surfactant-modified hydroxysalt exchanged with tetrachloropalladate Maby Mool Martínez Rogelio Ocampo-Cardona Jhon Mauricio Aguirre-Cortés Oscar Giraldo Luz Amalia Ríos-Vásquez Ingeniería Surfactant Anionic clays Tetrachloropalladate Palladium nanoparticles modified zinc hydroxychloride Palladium nanoparticles supported in the interlayer space of hydroxysalts were obtained from zinc hydroxychloride via a prior intercalation of the anionic surfactant sodium dodecyl sulfate (DS), followed by an exchange with potassium tetrachloropalladate and its final reduction to metallic palladium by ethanol. The final materials and their intermediates were characterized by several instrumental techniques such as PXRD, N2 adsorption, SEM, and TEM. The comparative analyses revealed clearly visible changes on structure, specific surface area and morphology of the reduced material with respect to the starting precursors. The analyses demonstrated that, upon modification of the starting material with the surfactant, the resulting material had a significantly enhanced interlayer space and BET area, which were fairly maintained until the reduced palladium-containing hydroxysalt was obtained. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49659032017 https://www.redalyc.org/journal/496/49659032017/ https://www.redalyc.org/journal/496/49659032017/html/ https://www.redalyc.org/journal/496/49659032017/49659032017.epub https://www.redalyc.org/journal/496/49659032017/movil 10.15446/dyna.v85n206.68132 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.206 Vol.85
