Abstract
Perovskite-type LaFeO3 and La1âxSrxFe1âyMnyO3 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 La1âxSrxFe1âyMnyO3 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.
