3D ORDERED MACROPOROUS TIO_2-SUPPORTED PT@CDS CORE-SHELL NANOPARTICLES FOR EFFICIENT PHOTOCATALYTIC CO_2 CONVERSION

摘要

In summary, we successfully fabricated 3DOM Pt@CdS/TiO_2rncatalysts via GBMR/P method. The structure of catalysts is welldefinedrnand uniformed. Moreover, 3DOM Pt@CdS/TiO_2 catalystsrnexhibit super catalytic activity for the photocatalytic reduction ofrnCO_2. The slow photon effect of 3DOM structure can improve thernlight-harvesting efficiency. The all-solid-state Z-scheme system withrnCdS(shell)-Pt(core)-TiO_2(support) nanojunction is favourable for thernseparation of photogenerated electrons and holes due to the vectorialrnelectron transfer of TiO_2→Pt→CdS. The fabrication of all-solid-staternZ-scheme system on 3DOM oxides surface is expected to throw newrnlight on the design of highly efficient photocatalyst for CO_2 reductionrnto hydrocarbon.
