文摘

The surface composition of TaF5 or NbF5 in [PMIm][Tf2N] and [BMP][Tf2N] is sensitive to the environmental contact; After contact to air a higher metal concentration is detected and the IL cation/anion ratio is modified; For samples not exposed to environmental conditions these strong changes are not observed;
