Effect of interlaminar cation type on the pillaring capacity of the synthetic mica Na-2-Mica and the in – situ formation to MnS Nanoclusters
In this work the Na-2-mica was synthesized by the sol-gel method and the effect of the cation exchange with lithium and hexadecylammonium, prior to the pillaring process with the Al Keggin’s polycation, was studied. The study was done by varying the density of pillars (10, 20 and 3...

The study was done by varying the density of pillars (10, 20 and 30 meq.Al3+ per gram of mica). The cation exchange with hexadecylammonium cations ensured the expansion of the interlayer; however, the study revealed that after the heat treatment in the pillaring process, the interlayer is not kept expanded, due to the high layer charge and the strongly acidic sites of mica. Most materials obtained formed particles of alumina (Al2O3) in the interlayer spacing, where the aluminum content and % CC increased as higher pillar density is provided. In addition, the formation of MnS nanoclusters in the pillared Al-2-mica was studied and the results indicated a limited growth of the nanoclusters respect to the Al content, due to amount interlayer alumina phase prevented proper diffusion of H2S(g) so they were deposited on the surface of the solid. All materials were mainly characterized by XRD, elemental analysis, analysis of the cation exchange capacity CEC and percentage of compensated charge -% CC.En este trabajo se sintetizó la Na-2-mica por el método sol – gel y se estudió el efecto del intercambio catiónico con litio y hexadecilamonio, previo al proceso de pilarización con el policatión de Keggin de Al, el estudio se realizó variando la densidad de pilares (10,20 y 30 meq. Al3+/g. de mica). El intercambio previo con cationes de hexadecilamonio garantizó la expansión de la interlámina; sin embargo el estudio reveló que después del tratamiento térmico en el proceso de pilarización, la interlámina no se mantiene expandida como lo hacen típicamente los minerales de arcilla pilareados, debido a la elevada carga laminar y a los sitios fuertemente ácidos de la mica. La mayoría de los materiales obtenidos formaron partículas de alúmina (Al2O3) en la interlámina. Adicionalmente se estudió la formación de nanoclusters de MnS incorporados en los materiales resultantes de la pilarización, cuya incorporación se vio restringida respecto al contenido de Al, posiblemente porque la fase alúmina interlaminar impidió el crecimiento de los nanoclusters, por lo que se depositaron sobre la superficie del sólido. Todos los materiales se caracterizaron principalmente por DRX, análisis elemental, estimación de la capacidad de intercambio catiónico CIC y porcentaje de carga compensada - % CC.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ciencia_en_desarrollo/article/view/7068/pdfDerechos de autor 2018 CIENCIA EN DESARROLLOhttp://purl.org/coar/access_right/c_abf2Ciencia En Desarrollo; Vol. 9 No. 1 (2018): Vol 9, Núm. 1 (2018): Enero - Junio; 119-132Ciencia en Desarrollo; Vol. 9 Núm. 1 (2018): Vol 9, Núm. 1 (2018): Enero - Junio; 119-1322462-76580121-7488Kegginmica sintética pilarizadaNa-2-micananoclusters de MnSCerámicosarcillassilicatos sintéticosKeggin, pillared mica, Na-2-mica, MnS nanoclusters.Effect of interlaminar cation type on the pillaring capacity of the synthetic mica Na-2-Mica and the in – situ formation to MnS NanoclustersEfecto del tipo de cation interlaminar sobre la capacidad de pilarización de la mica sintética na-2-mica y la formación in – situ de nanoclusters de MnSinfo:eu-repo/semantics/articleInvestigación Experimentalhttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1Ruiz Bravo, LisetteGaleano, Luis AlejandroPazos Zarama, Mery Carolina001/15231oai:repositorio.uptc.edu.co:001/152312025-07-18 10:56:40.221metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
