INCREASING HYDROGEN ADSORPTION OF NANOSTRUCTURES STORAGE MATERIALS BY MODIFYING SP2 COVALENT BONDS

摘要

According to the invention, nanostructured storage materials are provided for storing hydrogen. The nanostructured storage materials can include a network of light elements, such as Be, B, C, N, O, F, Mg, P, S, and Cl, coupled with sp<2> bonds. The hydrogen absorption to the nanostructured storage material is improved by modifying the sp2 bonds. The sp<2> bonds can be modified by forming the nanostructured storage material from the above light elements, possibly with a shape other than a planar layer, and by introducing defects. A chemical vapor deposition technique can be used for the synthesis, where doping gases are included into the flow. Methods for forming the nanostructured storage material with defects include removing lights elements from the nanostructured storage material by irradiation with electrons, neutrons, ions, gamma rays, X-rays and microwaves.
