摘要：
Nanostructured PbSnO3 photocatalysts with particulate and tubular morphologies have been synthesized from a simple hydrothermal process. As-prepared samples were characterized by X-ray diffraction, Brunauer-Emmet-Teller surface area, transmission electron microscopy, and diffraction spectroscopy. The photoactivities of the PbSnO3 nanostructures for isopropanol (IPA) degradation under visible light irradiation were investigated systematically, and the results revealed that these nanostructures show much higher photocatalytic properties than bulk PbSnO3 material. The possible growth mechanism of tubular PbSnO3 catalyst was also investigated briefly.
