Coordination polymer micro and nano particles are a new class of organic - inorganic hybrid micro-nano- materials with unique properties , such as redox , optical , magnetic, catalytic , hydrophobicity, hydrophilicity , while showing little size effect, quantum effect . These novel properties of the corresponding bulk materials can not match, so for the development and research of new materials has important significance. Recently, in our group found that micro- porous coordination polymer nanoparticles higher than the bulk of hydrogen adsorption enthalpy ; and under low pressure and / or high temperature, the hydrogen adsorption capacity higher than the corresponding bulk materials . In order to expand the research system , we successfully prepared nanostructures HKUST-1 and examine the corresponding gas adsorption properties . Main tasks are as follows : 1, HKUST-1 nanometer super structure at room temperature , trimesic acid ethanol solution and an aqueous solution of copper acetate mixed directly HKUST-1 was successfully prepared a nano super structure , and studied the low-pressure hydrogen adsorption . 2, HKUST-1 Nanocubes room temperature , concentration of reactants in the case of small , trimesic acid in ethanol -DMF solution and the aqueous copper acetate solution is directly mixed -DMF was successfully prepared nano cube HKUST-1 , and studied the low-pressure hydrogen adsorption properties . HKUST-1 nanometer super structure and HKUST-1 nanometer cube of hydrogen adsorption enthalpy than bulk HKUST-1 were increased by 9.96% , 21.10% ; but at lower pressure and / or high temperature hydrogen adsorption capacity of both higher than the bulk HKUST-1.
