Hydrogen fuel represents a promising solution to problems in green energy altenatives to power everything from laptops to aircraft. To pull up to the real world hydrogen storage is a key enabling technology for the advancement of hydrogen and fuel cell power tehonologies in transportation, stationary and portable application. Recently along with the development of nanotechnology a number of hydrogen storage techniques have been introduced that exploit the high-performance of hydogen storage to the nanostructured composites. Carbon nanotubes, among various nanostructured materials, is being studied by being decorated or dispersed with other metals to increase the hydrogen storage capacity, instead of used alone. MOF, one of supramolecular materials, is also being researched to increase the hydrogen storage capacity by being introduced the metal site, synthesized to composite form, or expanded the surface such as MOF-210, which has 6,240 m2/g BET surface area. Therefore, the main focus of current researches is to develope the material with introduction of metal site capable of hydrogen storage and promote the hydrogen storage capacity. As mentioned above, interactions of hydrogen with many kinds of metal ion introduced to nanostructure, and manganese is one of them. Among the binding energy of metal species and H2, manganese is also known well. Recently, it is reported that there were experiments for developing the hydrogen storage material using manganese ion for porous materals based on supramolecule. Due to the advantages of these supramolecule-based materials, temperature stability and easiness of structural transformation, many studies are being conducted on them as hydrogen storage material among nano porous materals but the hydrogen storage in room temperature are not good compared to the one in low temperature, and studies using dispersion-metal composite with large surface are still in progress. We reports that manganese silicate ultra-thin hollow nanospheres (MSHSs) using surfactant-free hydrothermal method to improve the energy storage capacity were synthesized in a smaller, simpler, easier and more uniform way than hollow spheres using other methods.
