Tomoyuki Kitano, Dr. Tetsuya Shishido, Dr. Kentaro Teramura and Prof. Dr. Tsunehiro Tanaka Characterization of Thermally Stable Brønsted Acid Sites on Alumina-Supported Niobium Oxide after Calcination at High Temperatures ChemPhysChem 14
Taking the heat: Thermally stable Brønsted acid sites are generated on Nb2O5/Al2O3 after calcination at high temperatures. Spectroscopic analysis shows that niobium oxide is supported as a monolayer domain and that the domains increase with increased loading up to 16 wt %. The Brønsted acid sites are generated at the boundaries of the niobium-oxide monolayer domains.
