Perovskite structural materials play an important role in the field luminous,catalytic and other functional materials,which is a hot spot of materials science research.Perovskite hollow structure CoSn（OH）6 nano-powder by solvent-assisted method using SnCl4,C2H6O,CoCl2 and Na3C6H5O7 as raw material.The phase structure and surface morphology of the samples were characterized by powder X-ray diffraction （XRD）,scanning electron microscopy （SEM）,transmission electron microscope（TEM） and X-ray photoelectron spectroscopy（XPS）.The electrocatalytic performances were tested by linear sweep voltammetry（LSV）.The results showed that the perovskite hollow structure CoSn（OH）6 powder with pure phase and 150 nm particle size was successfully produced by solvent-assisted method.CoSn（OH）6 nano-powder has a current of 35.1 mA/cm2and its Tafel slop is 72.5 mV/dec that is expected to be used in electrochemical hydrogen evolution.
