文摘

Nanostructured 3D porous Ti/Sb–SnO2–Gr was prepared by a LBL method with Gr hydrogel as scaffold. Oxygen evolution potential as high as 2.40 V was observed. Maximum production of OH radicals was reached. Remarkably improved catalytic activity and enhanced stability were achieved. Efficient decolorization of Rhodamine B at low energy cost was obtained.
