Hybrid inorganic-organic materials have become an important branch of materials chemistry with potential for a variety of applications including catalysis, separations, and gas storage. Much of the attraction of these materials consists in their ability to merge properties of classical solid state inorganic materials with the functionality of organic molecules. Hybrid nanoporous materials with highly variable pore volumes and surface functionalization, pore-accessible metal coordination sites, and catalytic active sites have been prepared. Microwave technique offer generally much faster, cleaner and more economical than the conventional method. Especially, the combination of microwave and solvothermal technique has several advantages for preparing nanoporous materials as follows; (a) less energy-consuming synthetic method, (b) the effective and selective heating to dielectric materials, and (c) mass-scale production. Very recently, Kim et al. reported a thermally stable, three dimensional, and nanoporous nickel 5-sulfoisophtalate at 180 oC for 2 days under hydrothermal condition. We present here the synthesis and application of nanoporous nickel 5-sulfoisophthalate [NaNi3(C8H3O7S)2(OH)(H2O)5H2O] by using microwave-solvothermal technique. This material prepares at 180 oC for 30 min or less using microwaves of 2.45 GHz frequency. This material shows selectivity in both solvents and gases based on molecular size and may find applications in hydrogen storage. |
