Functionalized Ordered Mesoporous Silica Composites As Potential Ammonia Storage Materials
Ammonia may provide an alternative energy supplier for its strong capability as hydrogen carrier. However, it is a problem that how to storage this kind of chemical at relatively high temperature, for example 300°C in fuel cell. In this work, a composite material based on metal halides and ordered mesoporous silica framework is developed and used to target ammonia at relatively high temperature. The silica framework is fabricated via evaporation induced self-assembly method and has tunable mesoporous structure with addition of hexadecyl trimethyl ammonium bromide (CTAB). Several metal salts at various concentrations are added to the mesoporous framework via wetness…
