description El control de la morfología, durante la síntesis de estructuras sólidas, se ha convertido en uno de los objetivos de estudio más importantes en el campo del diseño de nuevos materiales. Al modificar la forma y tamaño de las partículas de un sólido en polvo, sus propiedades fisicoquímicas pueden variar y obtenerse comportamientos excepcionales que conllevan a nuevas vías de aplicación tecnológica. Por tal motivo, en el presente trabajo se realizó una revisión documental sistemática y profunda acerca de los conceptos y principios que orientan la síntesis de óxidos de metales de transición con morfología multirramificada . Dichos principios permiten la comprensión del crecimiento controlado de dichas partículas. Inicialmente, a manera de estado del arte, se describen las generalidades de los óxidos de metales de transición, su importancia y aplicaciones, los tipos de morfologías y diferentes métodos de síntesis; luego se explican los mecanismos generales de formación de partículas cristalinas, según los parámetros termodinámicos y cinéticos que rigen la nucleación y su crecimiento. De igual manera, se discuten los factores químicos y físicos que influyen en la formación de partículas multirramificadas (multibranches), y finalmente se desarrolla la síntesis de micropartículas de óxido de hierro a diferentes condiciones de temperatura, tiempo y concentración, con el fin de estudiar la influencia de dichos parámetros en la síntesis hidrotérmica convencional de estas partículas. Las caracterizaciones básicas realizadas, SEM (microscopía electrónica de barrido), EDX (energía dispersiva de rayos X) y difracción de rayos X, demostraron la formación exitosa de partículas multirramificadas (con morfología de “hojas en forma de helecho”) de óxido de hierro con estructura hematítica (α-Fe2O3). A partir de estos resultados, se demuestra también el control en el tamaño de dichas partículas.

Al modificar la forma y tamaño de las partículas de un sólido en polvo, sus propiedades fisicoquímicas pueden variar y obtenerse comportamientos excepcionales que conllevan a nuevas vías de aplicación tecnológica. Por tal motivo, en el presente trabajo se realizó una revisión documental sistemática y profunda acerca de los conceptos y principios que orientan la síntesis de óxidos de metales de transición con morfología multirramificada . Dichos principios permiten la comprensión del crecimiento controlado de dichas partículas. Inicialmente, a manera de estado del arte, se describen las generalidades de los óxidos de metales de transición, su importancia y aplicaciones, los tipos de morfologías y diferentes métodos de síntesis; luego se explican los mecanismos generales de formación de partículas cristalinas, según los parámetros termodinámicos y cinéticos que rigen la nucleación y su crecimiento. De igual manera, se discuten los factores químicos y físicos que influyen en la formación de partículas multirramificadas (multibranches), y finalmente se desarrolla la síntesis de micropartículas de óxido de hierro a diferentes condiciones de temperatura, tiempo y concentración, con el fin de estudiar la influencia de dichos parámetros en la síntesis hidrotérmica convencional de estas partículas. Las caracterizaciones básicas realizadas, SEM (microscopía electrónica de barrido), EDX (energía dispersiva de rayos X) y difracción de rayos X, demostraron la formación exitosa de partículas multirramificadas (con morfología de “hojas en forma de helecho”) de óxido de hierro con estructura hematítica (α-Fe2O3). A partir de estos resultados, se demuestra también el control en el tamaño de dichas partículas.The control of morphology of solid structures, through the synthesis processes, has become one of the most important study objectives in the field of new material design. Modifying the shape and size of powder particles, their physical and chemical properties may be changed and exceptional performances with new technological applications can be obtained. Due to this perspective, in this work a deep and systematic review about the principles and concepts related to the synthesis of transition metal oxides with multibranched morphology was carried out. Said principles allow the understanding of controlled growth of the particles. First, as a state of the art, the basic concepts and generalities on the transition metal oxides, their applications and potential uses, the types of morphology and the different methods of synthesis are described. Afterward the general procedures for crystalline particle formation are explained, according to the thermodynamic and kinetic parameters which regulate both the nucleation and growth. In the same way, the chemical and physical factors influencing the formation of multibranched particles were discussed. Finally, the synthesis of iron oxide microparticles was carried out under different conditions of temperature, solution concentration and time. These variations were performed with the aim of studying the influence of such parameters on the conventional hydrothermal synthesis of the particles. The characterizations performed for the solids, SEM (scanning electron microscopy), EDX (energy dispersive X-ray analysis) and X-ray diffraction, confirmed the successful formation of multibranched particles (with morphology of “fern leaves”) of iron oxide having hematite structure (α-Fe2O3).Magíster en ciencias-Química.91application/pdfspaQuímica y ciencias afinesÓxido de metal de transición ; Partícula multirramificada ; Síntesis inorgánica ; Crecimiento de partícula ; Óxido de hierro ; HematitaTransition metal oxide ; Multibranched particle ; Inorganic synthesis ; Particle growth ; Iron oxide ; HematiteSíntesis de micropartículas multirramificadas de óxidos de metales de transiciónDocumento de trabajoinfo:eu-repo/semantics/workingPaperinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_8042Texthttp://purl.org/redcol/resource_type/WPUniversidad Nacional de Colombia - Sede BogotáDepartamento de QuímicaUniversidad Nacional de Colombia - Sede Bogotá1.
