▎ 摘  要

NOVELTY - Preparation of platinum/graphene oxide/ferric oxide catalyst, involves dispersing graphene oxide in water-soluble solution, adding ferric oxide nano material and platinum precursor solution, adding reducing agent to reduce platinum, subjecting solution to centrifugation, washing resulting solid with water and alcohol, drying and cooling, to obtain platinum/graphene oxide/ferric oxide catalyst. The total amount of platinum precursor solution, graphene oxide and ferric oxide nano material is 0.5-1.2 %mass. The reducing agent is sodium borohydride, potassium borohydride or hydrazine hydrate. USE - Preparation of platinum/graphene oxide/ferric oxide catalyst for catalytic oxidation of formaldehyde. ADVANTAGE - The catalytic oxidation activity of formaldehyde is enhanced.
