Efecto del MgB2 dopado sobre las propiedades de almacenamiento del sistema hidruro reactivo 2LiH+MgB2/2LiBH4+MgH2

Abstract

La utilización del H2 como vector de energía se considera como una de las alternativas más viables a la hora de reemplazar a los combustibles convencionales como por ejemplo el petróleo. Sin embargo, uno de los inconvenientes aún no resueltos es la falta de disponibilidad de un medio seguro, compacto y eficiente (en términos de autonomía) para el almacenamiento de hidrógeno principalmente para aplicaciones móviles [1, 2]. Una de las potenciales alternativas para poder superar dicho inconveniente es el almacenamiento de hidrógeno en estado sólido mediante la formación de compuestos denominados hidruros. El sistema hidruro 2LiH+MgB2/2LiBH4+MgH2 presenta interesantes características para el almacenamiento de hidrógeno. Este posee propicia estabilidad termodinámica, lo cual conlleva a una reducida temperatura de liberación de hidrógeno (ΔH = 40,5 kJ.mol-1 H2, Tliberación de hidrógeno = 225 ºC a 1 atm) [3, 4]. También presenta una elevada capacidad de almacenamiento de hidrógeno del 11,45 % p/p H2. A pesar de estas excelentes características, los resultados obtenidos han mostrado que el sistema hidruro absorbe-desorbe reversiblemente cantidades del 9 – 10 % p/p de hidrógeno a una temperatura relativamente elevada de 400 ºC [5]. El MgB2 es el compuesto que hace posible que el sistema hidruro absorba-desorba reversiblemente hidrógeno. Es por ello que se investiga si mediante el dopado del MgB2 con Al es posible disminuir la temperatura de reacción del sistema hidruro 2LiH+MgB2/2LiBH4+MgH2.
