The RF resin enabled uniform dispersion Fe-based and Ni-based nanoparticles through coordination with functional groups, while KCC-1 provided a high-surface-area, mesoporous support. A comprehensive structural and chemical characterization confirmed the formation of hematite in the Fe-based system; NiO and metallic Ni in the Ni-based material; and FeO, NiO and metallic Ni in the bimetallic composite, in the form of well-dispersed metal nanoparticles between 3\u20136 nm. Although a reduction in BET surface area was observed due to resin and metal loading, all nanocomposites retained mesoporous structures with Type IV isotherms and H3-type hysteresis, suitable for catalytic applications. The nanocomposites exhibited structural stability up to 800 \u00b0C under N2, with a total mass loss of 12\u201314% dominated by moisture desorption below 100 \u00b0C (~8\u201311%) and minor surface group degradation at higher temperatures. These findings demonstrate the potential of the PAD method for fabricating functional hybrid materials with improved metal dispersion.<\/jats:p>","DOI":"10.3390\/nano16171068","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T10:58:21Z","timestamp":1787828301000},"page":"1068","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Structural, Morphological, and Textural Characterization of Ni- and Fe-Based KCC-1@C Hybrid Nanocomposites"],"prefix":"10.3390","volume":"16","author":[{"given":"Luz D.","family":"Balbin-C\u00f3rdoba","sequence":"first","affiliation":[{"name":"Departamento de Qu\u00edmica, Facultad de Ciencias Naturales y Exactas, Universidad del Valle, Cali 760032, Colombia"},{"name":"Centro de Excelencia en Nuevos Materiales (CENM), Universidad del Valle, Cali 760032, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1490-6305","authenticated-orcid":false,"given":"Juli\u00e1n","family":"Vanegas-Ramirez","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica, Facultad de Ciencias Naturales y Exactas, Universidad del Valle, Cali 760032, Colombia"},{"name":"Centro de Excelencia en Nuevos Materiales (CENM), Universidad del Valle, Cali 760032, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3640-1338","authenticated-orcid":false,"given":"Lorena","family":"Mar\u00edn","sequence":"additional","affiliation":[{"name":"Centro de Excelencia en Nuevos Materiales (CENM), Universidad del Valle, Cali 760032, Colombia"},{"name":"Grupo de Pel\u00edculas Delgadas (GPD), Departamento de F\u00edsica, Universidad del Valle, Cali 760032, Colombia"},{"name":"Direcci\u00f3n de Laboratorios, Servicio Geol\u00f3gico Colombiano, Cali 760031, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis A.","family":"Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Centro de Excelencia en Nuevos Materiales (CENM), Universidad del Valle, Cali 760032, Colombia"},{"name":"Grupo de Transiciones de Fase y Materiales Funcionales, Departamento de F\u00edsica, Facultad de Ciencias Naturales y Exactas, Universidad del Valle, Cali 760032, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6761-6171","authenticated-orcid":false,"given":"C\u00e9sar","family":"Mag\u00e9n","sequence":"additional","affiliation":[{"name":"Instituto de Nanociencia y Materiales de Arag\u00f3n (INMA), CSIC-Universidad de Zaragoza, 50009 Zaragoza, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6378-6133","authenticated-orcid":false,"given":"Jes\u00fas A.","family":"Tabares","sequence":"additional","affiliation":[{"name":"Centro de Excelencia en Nuevos Materiales (CENM), Universidad del Valle, Cali 760032, Colombia"},{"name":"Grupo de Metal\u00fargica F\u00edsica y Teor\u00eda de Transiciones de Fase (GMTF), Departamento de F\u00edsica, Universidad del Valle, Cali 760032, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milton","family":"Manotas-Albor","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n en F\u00edsica Aplicada (GIFA), Departamento de F\u00edsica y Geociencias, Universidad del Norte, Barranquilla 080001, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renso","family":"Visbal","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica, Facultad de Ciencias Naturales y Exactas, Universidad del Valle, Cali 760032, Colombia"},{"name":"Centro de Excelencia en Nuevos Materiales (CENM), Universidad del Valle, Cali 760032, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0907-1772","authenticated-orcid":false,"given":"Malka","family":"Mora","sequence":"additional","affiliation":[{"name":"Departamento de Qu\u00edmica, Facultad de Ciencias Naturales y Exactas, Universidad del Valle, Cali 760032, Colombia"},{"name":"Centro de Excelencia en Nuevos Materiales (CENM), Universidad del Valle, Cali 760032, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Tripathy, J., Mishra, A., Pandey, M., Thakur, R.R., Chand, S., Rout, P.R., and Shahid, M.K.
