摘      要：The construction of inorganic porous frameworks from discrete polyoxometalate(POM)units is a major research ***,a three-dimensional(3D)all-inorganic porous structure{Mo_(154)}_n that consists of classic Mo_(154)rings connected by Mo–O–Mo covalent bonds was ***,the proton conductivity of the 3D-{Mo_(154)}_n framework is 1.1×10^(-2)S cm^(-1)at 22℃and 100%relative humidity(RH),which is one of the highest proton conductivities reported thus far for POM-based conductive *** to the discrete{Mo_(154)}cluster and 1D-{Mo_(154)}_n,the enhanced conductivity of 3D-{Mo_(154)}_n suggests that assembling POM-based all-inorganic porous frameworks is a promising method for designing proton-conductive materials.
