Claims20
A core-shell nanoparticle comprising:
- a core material comprising a metal core and a metal oxide shell, wherein the metal oxide shell has catalytic activity;
- and
- a mesoporous silica layer at least partially encapsulating the core material, wherein the core-shell nanoparticle has a size from about 10 nm to about 200 nm.
A core-shell nanoparticle comprising:
- a hollow nanosphere comprising a metal oxide shell and a cavity, wherein the metal oxide shell has catalytic activity;
- and
- a mesoporous silica layer at least partially encapsulating the hollow nanosphere, wherein the core-shell nanoparticle has a size from about 10 nm to about 200 nm.
A core-shell nanoparticle comprising:
- a metal core comprising at least one of Mn, Fe, Co, Ni, Cu, Zn, Ru, Rh, Pd, Ag, In, Sn, Re, Os, Ir, Pt, Au, a lanthanoid, or alloys thereof;
- a metal oxide layer at least partially encapsulating the metal core, wherein the metal oxide layer comprises at least one of TiO2, CeO2, V2O3, ZnO, ZrO2, SnO2, WO3, Fe2O3, V2O2, or MoO3;
- and
- a mesoporous silica layer at least partially encapsulating the metal oxide layer.
