Facile synthesis and characterizations of mof-5 coordination polymer with various metal linker ratios for ammonia gas storage
Metal-organic framework coordination polymer materials of MOF-5 with Fm3m cubic structure and tetrahedral structure were successfully synthesized at room temperature and pressure using liquid-crystal (i.e. surfactant) templating method and direct mixing method. The crystallinity increased as metal (...
