Determinación del área superficial de redes organometálicas mediante técnicas termogravimétricas

Se plantea un modelo matemático fundamentado en los principios del modelo BET para la medición de áreas superficiales y en la teoría de adsorción de Polanyi, con base en el fenómeno de desorción ocurrido en el análisis termogravimétrico de los MOFs. El modelo se realiza con el objetivo de encontrar...

Is proposed a mathematical model grounded on the principles of BET method and the Polanyi adsorption theory; It is based on the desorption phenomenon occurred in thermogravimetric analysis of Metal-Organic Frameworks (MOFs). The objective is to measure the surface areas of porous materials. The model is made with the aim of finding the coordination polymers surface area from the results achieved by the materials weight loss at certain temperatures. Two different familieas of coordination polymers (ZrBTC and CuBTC) are synthesized at different conditions. It was studied the behavior of weight loss with increasing the temperature in the thermogravimetric analysis for each material and surface area measurements were performed using the BET model. Subsequently
it was found that there is a relationship between the weight loss measured by thermogravimetric analysis and the surface area reported by the BET model
which shows that these two results are directly proportional to the adsorption capacity of the porous materials. The proposed mathematical model is implemented
and yields satisfactory results when calculating the surface areas of both MOFs families
with close values to those obtained by the BET model. The results for the two families of coordination polymers were compared
and It is determined that the model gives a better fitting for the synthesized MOF ZrBTC. 1

description Se plantea un modelo matemático fundamentado en los principios del modelo BET para la medición de áreas superficiales y en la teoría de adsorción de Polanyi, con base en el fenómeno de desorción ocurrido en el análisis termogravimétrico de los MOFs. El modelo se realiza con el objetivo de encontrar el área superficial de polímeros de coordinación a partir de los resultados arrojados por la pérdida del peso del material a ciertas temperaturas. Se realizó la síntesis a diferentes condiciones de dos familias de polímeros de coordinación (CuBTC y ZrBTC). Se estudió para cada material el comportamiento de la pérdida de peso con el aumento de la temperatura en el análisis termogravimétrico y se realizaron mediciones del área superficial mediante el modelo BET. Posteriormente, se encuentra una relación de la pérdida de peso arrojada por el análisis termogravimétrico y el área superficial reportada por el modelo BET, donde se observa que estos dos resultados son directamente proporcionales a la capacidad de adsorción de los materiales. Se implementa el modelo matemático planteado y este arroja resultados satisfactorios al calcular las áreas superficiales de ambos materiales, con valores cercanos a los obtenidos por el modelo BET. Los resultados para las dos familias de polímeros de coordinación fueron comparados y se determinó que el modelo da un mejor ajuste para el MOF ZrBTC. 1
