Abstract

The fabrication of Pt nanoparticles encapsulated in hollow carbon nanospheres using TiO2 nanoparticles as both the photocatalyst and the inorganic mold is demonstrated (see figure). These spheres are found to have high surface area and ultrathin shells with well-developed microporosity, and thus can be used as catalysts. This new imprinting method can be used to synthesize any desired nanostructures using predesigned TiO2 photocatalysts.

22. In control experiments in which SiO2and Al2O3were employed instead of TiO2 no formation of polymeric compounds was observed under the present reaction conditions. Thus the observed polymerization occurred through the photocatalytic reaction of TiO2.

24. The formation of resorcinol is less probable through such phenoxy‐radical intermediates. Hence other pathways should also be included. Detailed studies for further identifications are now underway.

30. The presence of CS on activated carbons generally leads to an overestimation of specific surface area (SA) of the samples by routine BET analysis. Therefore we determined the SA of the present materials using the slope of the αsplot.
