Controlled synthesis of Pt-loaded yolk-shell TiO2@SiO2 nanoreactors as effective photocatalysts for hydrogen generation
文献摘要：
Yolk-shell and hollow structures are powerful platforms for controlled release,confined nanocatalysis,and optical and electronic applications.This contribu-tion describes a fabrication strategy for a yolk-shell nanoreactor(NR)using a post decoration approach.The widely studied yolk-shell structure of silica-coated TiO2(TiO2@SiO2)was used as a model.At first,anatase TiO2 spheres were prepared,and subsequently were given a continuous coating of carbonaceous and silica layers.Finally,the carbonaceous layer was removed to produce a yolk-shell structure TiO2@SiO2.By using an in-situ photodeposition method,Pt-encased spheres(Pt-TiO2@SiO2)were synthesized with Pt nanoparticles grown on the surface of the TiO2 core,which contained void spaces suitable for use as NRs.The NR showed enhanced hydrogen production with a rate of 24.56 mmol·g-1·h-1 in the presence of a sacrificial agent under simulated sunlight.This strategy holds the potential to be extended for the synthesis of other yolk-shell photocatalytic NRs with different metal oxides.
