High-temperature surface enhanced Raman spectroscopy for in situ study of solid oxide fuel cell materials

In situprobing of surface species and incipient phases is vital to unraveling the mechanisms of chemical and energy transformation processes. Here we report Ag nanoparticles coated with a thin-film SiO sub(2) shell that demonstrate excellent thermal robustness and chemical stability for surface enha...

Zusammenfassung:	In situprobing of surface species and incipient phases is vital to unraveling the mechanisms of chemical and energy transformation processes. Here we report Ag nanoparticles coated with a thin-film SiO sub(2) shell that demonstrate excellent thermal robustness and chemical stability for surface enhanced Raman spectroscopy (SERS) study of solid oxide fuel cell materials under in situconditions (at similar to 400 degree C).
