Catalytic H2 Oxidation on TiO2/Nanoporous Au; Towards Engineering TiO2/Au Interface |
| 초록 |
Nanoporous gold (np-Au) is a novel three dimensional, bicontinous and interconnected nanostructured monolithic material which serves as promising platform to design tailored catalysts via controlled surface modification through oxide deposition such as TiO2 to assess catalytic activity for H2 oxidation. In this work, we fabricated nanoporous Au films (~150 nm thick) of varying porosity and compositions by de-alloying Si from AuxSi1-x alloy. Inverse TiO2/np-Au catalysts were synthesized by oxide deposition on np-Au via titanium isopropoxide (TTIP) impregnation. In order to evoke high catalytic activity from interface at TiO2/np-Au junction, concentration of TTIP precursor is varied (using 0.1, 0.5 and 1 Wt. % TTIP) in liquid phase deposition. |
