Abstract: Under the solvothermal conditon,a tetrahedral silicon-centred linker with space-directed was employed to successfully construct one novel MOFs,namely,[Co3O(H2O)3L(ttb)]·3H2O (MOF-Co).It was structurally confirmed by test.The adsorption ability of dye molecules in dye aqueous solution was also tested.The results showed that the structure of MOF-Co was pure phase and had good thermal stability,chemical stability and large pore channels.Under the conditions of 12mg/L of methylene blue solution,10mg of MOF-Co and 6h of adsorption,the maximum adsorption rate of methylene blue was 62.3%.
