- Abstract
Firstly, H3[P(W3O10)4]@MOF-199 nanoparticles (PTA@MOF-199) of uniform morphology, about 80-125 nm, were successfully synthesized by a simple one-step reaction under solvothermal conditions and then these as-prepared nanoparticles were incorporated into polyvinyl alcohol (PVA) and polyvinyl pyrrolidone (PVP) with solution-cast technique to fabricate a series of proton-conducting mixed matrix membranes with different mass percentage of PTA@MOF-199. These membranes were characterized by XRD and FT-IR. Afterwards, the influence of the mass percentage of PTA@MOF-199 and temperature on the proton-conducting properties were evaluated. Our work confirmed that the polyoxometalate (POM) functionalized MOFs had great application potential as proton conductive materials and provided a basis for further studies on other POM@MOFs based proton-conducting membranes fabrication.
