Fabrication of heterogeneous catalysts using atomic layer deposition |
| 초록 |
We show two different strategies of use of atomic layer deposition for fabricating highly stable heterogeneous catalysts. First, atomic layer deposition can be used for incorporation of catalytically active NiO nanoclusters into mesoporous silica and alumina with a mean pore size of ~ 10-15 nm. Catalytic activity of the supported Ni oxide nanoclusters was tested for CO and toluene oxidation. As a second strategy, we show that atomic layer deposition can provide porous and thin shells wrapping catalytically active nanoparticles, and these shells can inhibit deactivation of catalysts operating under high temperatures (above 800 oC). As an example, we show that TiO2 and MgO shells on Ni particles can reduce poisoning of these catalysts in CO2 reforming of methane reaction, due to the fact that these shells can inhibit deposition of coke on the surface of Ni catalysts. |
