摘要

Nb/Al₂O₃ and Nb/SiO₂ as niobium carbide precursors were prepared from peroxoniobic acid (PNA). Alumina-supported niobium carbide and silica-supported niobium carbide were prepared by temperature programmed reaction (TPR) method under CH₄–H₂ mixed gas passage. Both catalysts were characterized by X-ray absorption fine structure (XAFS) and Raman spectroscopy. Nb/Al₂O₃ was more efficiently carburized than Nb/SiO₂. The carbon deposition onto NbC occurred after the carburization completion of the Nb species.
