英文摘要	perovskite-type lafeo3 and la1-xsrxfe1-ymnyo3 hollow nanospheres were prepared, for the first time, via a urea-assisted one-pot solvothermal method. the chemical compositions, crystalline phases, specific surface areas and morphologies of the materials as-prepared were characterized by icp-oes, xrd, nitrogen adsorption and tem, respectively. it was found that the presence of urea greatly decreased the nucleation temperature which led to the smaller particle sizes of products. as a potential application, the materials as-prepared exhibited superior activity and good stability in the catalytic decomposition of hydrogen peroxide. the excellent activity of la1-xsrxfe1-ymnyo3 hollow nanospheres can be rationalized by their high specific surface areas and hollow nanoparticle morphology. the high stability of these materials can be attributed to their perovskite-type crystal structures.
