摘要:
The present invention concerns a method for producing an alkene, the method comprising a step of converting an alcohol by a dehydration step into an alkene with cerium oxide particles as catalyst. Method of the present invention notably permits the production of ethanol, propanol, butanol and pentanol.
摘要:
The present invention relates to cerium oxide particles that have excellent heat resistance especially useful for catalysts, functional ceramics, solid electrolyte for fuel cells, polishing, ultraviolet absorbers and the like, and particularly suitable for use as a catalyst or co-catalyst material, for instance in catalysis for purifying vehicle exhaust gas. The present invention also relates to a method for preparing such cerium oxide particles, and a catalyst, such as for purifying exhaust gas, utilizing these cerium oxide particles.
