▎ 摘  要

NOVELTY - A cerium oxide-molybdenum trioxide/graphene low temperature denitration catalyst comprises 5-15 mass% cerium oxide, 5-10 mass% molybdenum trioxide, and balance graphene. USE - A cerium oxide-molybdenum trioxide/graphene low temperature denitration catalyst (claimed). ADVANTAGE - Catalyst has good denitration property and improved nitrogen oxide (NOx) reduction rate, and inhibits oxidation of sulfur dioxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of cerium oxide-molybdenum trioxide/graphene low temperature denitration catalyst which involves washing 75-90 pts. wt. graphene with water, drying, standing, mixing graphene and deionized water to obtain mixture (A), adding cerium nitrate solution with cerium content of 5-15 pts. wt. in mixture (A), stirring to obtain mixture (B), dissolving 5-10 pts. wt. molybdenum trioxide in aqueous ammonia to obtain solution (B), mixing with mixture (B) containing 75-90 pts. wt. graphene, adjusting pH to 1 using concentrated nitric acid, carrying out shock conditions drying to obtain mixture (C), calcining in muffle furnace at 350 degrees C under protection of nitrogen gas (N2), and grinding in which catalyst contains 100 pts. wt. graphene, cerium oxide, and molybdenum trioxide.
